- Twisted Lime worm ( Serpula contortuplicata )
In the Serpulacees ( Serpulacea ), the gills are located entirely at the front end of the body; the cilia that coat her cause a current to flow into the water, which supplies food to the mouth opening immediately below it. The head segment is not separated from the mouth segment, as is the case with most other Ringworms, but has grown together with it. - Tutored Bear.—XIV. Century
One great part of the joculator's profession was the teaching of bears, apes, horses, dogs, and other animals, to imitate the actions of men, to tumble, to dance, and to perform a variety of tricks, contrary to their nature; and sometimes he learned himself to counterfeit the gestures and articulations of the brutes. - Tutored Bear.—XIV.

- Turkey Vulture
Turkey Vulture Vultures play an unusual part in nature’s drama. They, along with Sexton Beetles, other insects and animals, form the sanitary unit. When we consider the heavy toll of wildlife along our highways, we can appreciate the usefulness of such a unit. Lacking talons, vultures are not equipped to catch their prey, but feed on whatever nature provides. This vulture is almost eagle size, with a wingspread of 70 inches and can be identified by his long tail, small head, 2-toned wings, and habit of soaring, the wings forming a dihedral or open V-shape. On close inspection, you will find the head bare and a reddish color. The young have blackish heads which is one of the marks of the Black Vulture, but the latter is smaller with a square tail and shows white spots under the wing when flying. This is a southern cousin. - Tulbaghia violacea
Tulbaghia violacea - Tufted Titmouse
Tufted Titmouse This sparrow-size cousin of the chickadee has a tuft of feathers which gives him a striking appearance. The tuft, nape, back, wings and tail are slate gray, while the cheek, throat, breast and belly are white with a pinkish-brown patch just below the wing. Habits are similar to chickadees and he often can be found feeding in loose flocks with these and other small birds such as Downy Woodpeckers, nuthatches and Brown Creepers. Together they form a useful team for what one species misses by his method of feeding, one of the others will find by a slightly different method. They nest in holes in trees or even a bird box to their liking. They are noisy birds and their song is much louder and clearer than you would expect to hear from such small singers. The song consists of a series of whistled notes which sound like “pet-er” or “pet-o,” the first note usually slightly higher. Other notes remind you of a Carolina Wren or a Kentucky Warbler but the phrasing and tempo soon lead you to proper identification. A titmouse enjoys a well-stocked feeder and is a nice neighbor for he enjoys singing and the clear whistled notes add a touch of nature to a cold winter day. - Trypanosoma Ziemanni, from the gut of the gnat
Trypanosoma Ziemanni, from the gut of the gnat - Trypanosoma Ziemanni, from the blood of the little owl
Trypanosoma Ziemanni, from the blood of the little owl. The stages shown in Figs. 52–54 are passed inside the gnat. The spiral and pear-shaped bodies of Fig. 54 pass from the gnat’s proboscis into the blood of the little owl, and grow there into the large forms here figured. A, B, and C are females, destined to be fertilized by spermatozoa when swallowed by a gnat. D and E are male Trypanosomes, which will give rise each to eight fertilizing individuals or spermatozoa as shown in Fig. 56—when swallowed by a gnat. - Trypanosoma brucei
By trypanosomiasis is meant a condition of animal parasitism, common to man and the lower animals, in which trypanosomes, peculiar flagellate protozoa, infest the blood. Depending upon the species, they may be harmless, producing no appreciable ill-effect, or pathogenic, giving rise to conditions of disease. A number of these are known to be transferred by insects. The trypanosomes are elongated, usually pointed, flagellated protozoa in which the single flagellum, bent under the body, forms the outer limit of a delicate undulating membrane. It arises near one end of the organism from a minute centrosome-like body which is known as the blepheroplast, and at the opposite end extends for a greater or less distance as a free flagellum. Enclosing, or close beside the blepheroplast is the small kinetonucleus. The principal nucleus, round or oval in form, is situated near the center of the body. Asexual reproductions occurs in this stage, by longitudinal fission, the nucleus and the blepheroplast dividing independently of one another. From the blepheroplast of one of the daughter cells a new flagellum is formed. - Trout

- Tree-porcupine
The Mexican Tree Porcupine [Cercolabes (Sphingurus) novae-hispaniae], an animal of 95 cM. total length, of which about a third must be counted for the tail, inhabits the east coast of Mexico. The shiny hairs are very dense and soft, a little frizzy and so long, that many spines are completely covered by them. The spines are also missing from the parts, with the exception of the lower neck, on the inside of the legs, on the snout and on the rear half of the tail, which is covered from above naked, from below with black, on the sides with yellow brushes. - Tree Swallow
Tree Swallow Iridoprocne bicolor The frost hardly has left the ground, or the peepers and cricket frogs assembled their chorus, when flocks of these swallows can be seen winging their way northward. First flights include only the rugged males which arrive well in advance of their mates. They also are one of the last species of swallows to migrate in the fall. These birds show whitish under parts, while the upper parts are a greenish steel-blue. Western observers might confuse this bird with the Violet-green Swallow but remember that the latter shows a conspicuous white patch on each side of the rump. Tree Swallows prefer a location near water and soon will occupy holes in stumps so located: however, bird houses are acceptable. They do not choose to nest in colonies and will defend their nesting site with vigor. Those who erect nesting boxes for these swallows might find it necessary to help them evict House Sparrows which often take a liking to their homes. Flying insects form the major portion of this bird’s food. These include numerous mosquitoes and other insects which hatch on or near water, for that seems to be their favorite feeding ground. Other foods include bayberry and wax myrtle berries, which are sought during migration. - Tree falcon

The figure represents a tortoise. When one sees a resemblance between this creature's head and neck and the linga, one can understand why both in. India and in Greece the animal should be regarded as sacred to the goddess personifying the female creator, and why in Hindoo myths it is said to support the world. - Topography of a Bird

- Three Spined Stickleback
The male stickleback, as many of you may know, builds a wonderful nest, in which, when finished, he invites his chosen mate to lay her eggs. As soon as these precious treasures have been entrusted to his care, he makes himself their sole guardian, forcing currents of fresh water through the nest by the violent fanning motion of his breast-fins, and driving away all that come near. Strangely enough, he has to exercise the greatest care to keep out his mate, who would eat every single egg if she could but get the chance! - Three kittens and a basket

- The ‘Wonderful Cynocephalus’
For a trainer to break a monkey so as to ride a horse, carry a miniature flag, and hold on by the reins, is commonly considered a remarkable achievement. Occasionally though a monkey rider has been exhibited who has really performed in a manner not merely absurd. The most notable example of this kind was a huge ape of the cynocephalus or dog face family, exhibited in the winter of 1867–8 at Lent’s New York Circus, under the title of the “Wonderful Cynocephalus.” - THE ZOEA OF THE COMMON CRAB

- The young of the common Eel and its metamorphosis
Drawings by Professor Grassi, of Rome, of the young of the common Eel and its metamorphosis. All of the natural size. The uppermost figure represents a transparent glass-like creature—which was known as a rare “find” to marine naturalists, and received the name Leptocephalus. Really it lives in vast numbers in great depths of the sea—five hundred fathoms and more. It is hatched here from the eggs of the common Eel which descends from the ponds, lakes, and rivers of Europe in order to breed in these great depths. The gradual change of the Leptocephalus into a young Eel or “Elver” is shown, and was discovered by Grassi. The young Eels leave the great depth of the ocean and ascend the rivers in immense shoals of many hundred thousand individuals, and wriggle their way up banks and rocks into the small streams and pools of the continent. - The yellow fever mosquito (Aëdes calopus)
- The Woolly Kangaroo
The Woolly Kangaroo - The Wolf among the Sheep. (John x. 12)
There is no doubt that the Hebrew word Zeëb, which occurs in a few passages of the Old Testament, is rightly translated as Wolf, and signifies the same animal as is frequently mentioned in the New Testament. - The White Yak of the Asiatic Mountains
This animal has a thick coat of long, silky hair, which hangs nearly to the ground. Ropes and cloth are made from it. The tail is just a great[96] bunch of long hair. The Yak does not bellow like the ox but gives a short grunt. Its milk is very rich, and fine butter is made from it. - The Wanderoo
There is one species of monkey, which is extremely likely to have been brought to Palestine, and used for the adornment of a luxurious monarch's palace. This is the Wanderoo, or Nil-Bhunder (Silenus veter). The Wanderoo, or Ouanderoo, as the name is sometimes spelled, is a very conspicuous animal, 7on account of the curious mane that covers its neck and head, and the peculiarly formed tail, which is rather long and tufted, like that of a baboon, and has caused it to be ranked among those animals by several writers, under the name of the Lion-tailed Baboon. - The unicellular parasite Benedenia, from the gut of the common Poulp or Octopus
The unicellular parasite Benedenia, from the gut of the common Poulp or Octopus. 1 is the normal male individual; 2 and 3 show stages in the production of spermatozoa on its surface by budding; 4, 5 and 6 show a female parasite with spermatozoa approaching it. - The two wise cart-horses
Cart-horses, though heavy-looking animals, are more sagacious that their more gracefully formed relatives. A cart-horse had been driven from a farmyard to the neighbouring brook early one morning during winter to drink. The water was frozen over, and the horse stamped away with his fore-feet, but was unable to break the ice. Finding this, he waited till a companion came down, when the two, standing side by side, and causing their hoofs to descend together, broke through the ice, and were thus enabled to obtain the water they required. - The Two White Birds
The Two storks - The Three-banded Armadillo. An Animal in a Coat of Mail
The armadillo is an American animal, and is found in our country in the state of Texas. It goes south from there through Mexico and on to South America, where it is found everywhere. It lives in large numbers in the woods and on the great grass plains. In its food and habits it is much like the hedgehog, and like it burrows in the ground. To do this it has very strong claws, and these it can use to defend itself when it takes a fancy to fight.
