The Angora goat is, perhaps, scarcely a distinct species. If not identical with the ordinary wild goat of Persia and Mesopotamia (Capra cegagrus), he is at any rate closely allied to it; and it is possible that all his peculiar characteristics may be the effect of climate. He has a soft, white, silky fleece, very long, divided down the back by a strong line of separation, and falling on either side in beautiful spiral ringlets; his fleece weighs from two to four pounds. It is of nearly uniform, length, and averages from five to five and a half inches.
The elk is said to inhabit Armenia, Affghanistan, and the lower part of the valley of the Indus; but it is perhaps not certain that he is really to be found in the two latter regions. Monkeys abound in Eastern Oabul and the adjoining parts of India. They may have also existed formerly in Upper Egypt. The spotted hyena, Felis chaus (Canis crocuta of Linnaeus), is an Egyptian animal, inhabiting principally the hills on the western side of the Nile. In appearance it is like a large cat, with a tuft of long black hair at the extremities of its ears—a feature which it has in common with the lynx.
Among the rarer birds of the Empire may be mentioned the ostrich, which occurred in Mesopotamia; parrots, which were found in Cabul and the Punjab; ibises, which abounded in Egypt, and in the Delta of the Indus, the great vulture (Vultur cinereus), which inhabited the Taurus, the Indian owl (Athena Indica), the spoonbill (Platalea nudifrons); the benno (Ardea bubulcus), and the sicsac (Charadrius melanocephalus).
The most valuable of the fish belonging to the Persian seas and rivers were the pearl oyster of the Gulf, and the murex of the Mediterranean, which furnished the famous purple dye of Tyre. After these may be placed the sturgeon and sterlet of the Caspian, the silurus of the Sea of Aral, the Aleppo eel, and the palla, a small but excellent fish, which is captured in the Indus during the flood season. The Indian Ocean and the Persian Gulf, as we have seen, were visited by whales; dolphins, porpoises, cod, and mullet abounded in the same seas; the large rivers generally contained barbel and carp; while some of them, together with many of the smaller streams, supplied trout of a good flavor. The Nile had some curious fish peculiar to itself, as the oxyrinchus, the lepidotus, the Perca Nilotica, the Silurus Schilbe Niloticus, the Silurus carmuth and others. Great numbers of fish, mostly of the same species with those of the Nile, were also furnished by the Lake Moeris; and from these a considerable revenue was derived by the Great Kings.
Among the more remarkable of the reptiles which the Empire comprised within its limits may be noticed—besides the great saurians already mentioned among the larger animals—the Nile and Euphrates turtles (Trionyx Egypticus and Trionyx Euphraticus), iguanas (Stellio vulgaris and Stellio spinipes), geckos, especially the Egyptian house gecko (O. lobatus), snakes, such as the asp (Coluber haje) and the horned snake (Coluber cerastes), and the chameleon. The Egyptian turtle is a large species, sometimes exceeding three feet in length. It is said to feed on the young of the crocodile. Both it and the Euphrates turtle are of the soft kind, i.e., of the kind which has not the shell complete, but unites the upper and under portions by a coriaceous membrane. The turtle of the Euphrates is of moderate size, not exceeding a a length of two feet. It lives in the river, and on warm days suns itself on the sandbanks with which the stream abounds. It is active, strong, violent, and passionate. When laid on its back it easily recovers itself. If provoked, it will snap at sticks and other objects, and endeavor to tear them to pieces. It is of an olive-green color, with large irregular greenish black spots.
Iguanas are found in Egypt, in Syria, and elsewhere. The most common kind (Stellio vulgaris) does not exceed a foot in length, and is of an olive color, shaded with black. It is persecuted and killed by the Mahometans, because they regard its favorite attitude as a derisive imitation of their own attitude of prayer. There is another species, also Egyptian, which is of a much larger size, and of a grass-green color. This is called Stellio spinipes: it has a length of from two to three feet.
The gecko is a kind of nocturnal lizard. Its eyes are large, and the pupil is extremely contractile. It hides itself during the day, and is lively only at nights. It haunts rooms, especially kitchens, in Egypt, where it finds the insects which form its ordinary food. Its feet constitute its most marked characteristic. The five toes are enlarged and furnished with an apparatus of folds, which, by some peculiar action, enable it to adhere to perfectly smooth surfaces, to ascend perpendicular walls, cross ceilings, or hang suspended for hours on the under side of leaves. The Egyptians called it the abu burs, or “father of leprosy,” and there is a wide-spread belief in its poisonous character; but modern naturalists incline to regard the belief as unfounded, and to place the gecko among reptiles which are absolutely harmless.
The asp of Egypt (Coluber haje) is a species of cobra. It is a large snake, varying from three to six feet in length, and is extremely venomous. It haunts gardens, where it is of great use, feeding on mice, frogs, and various small reptiles. It has the power of greatly dilating the skin of the neck, and this it does when angered in a way that is very remarkable. Though naturally irritable, it is easily tamed; and the serpent-charmers of the East make it the object of their art more often than any other species. After extracting the fangs or burning out the poison-bag with a red-hot iron, the charmer trains the animal by the shrill sounds of a small flute, and it is soon perfectly docile.
The cerastes is also employed occasionally by the snake-charmers. It has two long and thin excrescences above the eyes, whereto the name of “horns” has been given: they stand erect, leaning a little backwards; no naturalist has as yet discovered their use. The cerastes is of a very pale brown color, and is spotted with large, unequal, and irregularly-placed spots. Its bite is exceedingly dangerous, since it possesses a virulent poison; and, being in the habit of nearly burying itself in the sand, which is of the same color with itself, it is the more difficult of avoidance. Its size also favors its escaping notice, since in length it rarely much exceeds a foot.
The chameleon has in all ages attracted the attention of mankind. It is found in Egypt, and in many others parts of Africa, in Georgia, and in India. The power of changing color which it possesses is not really its most remarkable characteristic. Far more worthy of notice are its slow pace, extraordinary form, awkward movements, vivacity, and control of eye, and marvellous rapidity of tongue. It is the most grotesque of reptiles. With protruding and telescopic eyes, that move at will in the most opposite directions, with an ungainly head, a cold, dry, strange-looking skin, and a prehensile tail, the creature slowly steals along a branch or twig, scarcely distinguishable from the substance along which it moves, and scarcely seeming to move at all, until it has come within reach of its prey. Then suddenly, with a motion rapid as that of the most agile bird, the long cylindrical and readily extensile tongue is darted forth with unerring aim, and the prey is seized and swallowed in a single moment of time. The ordinary color of the chameleon is a pale olive-green. This sometimes fades to a sort of ashen-gray, while sometimes it warms to a yellowish-brown, on which are seen faint spots of red. Modern naturalists, for the most part, attribute the changes to the action of the lungs, which is itself affected chiefly by the emotions of anger, desire, and fear.
The great extent of the Empire caused its vegetable productions to include almost all the forms known to the ancient world. On the one hand, the more northern and more elevated regions bore pines, firs, larches, oaks, birch, beech, ash, ilex, and junipers, together with the shrubs and flowers of the cooler temperate regions; on the other hand, the southern tracts grew palms of various kinds, mangoes, tamarind-trees, lemons, oranges, jujubes, mimosas, and sensitive plants. Between these extremes of tropical and cold-temperate products, the Empire embraced an almost infinite variety of trees, shrubs, and flowers. The walnut and the Oriental plane grew to avast size in many places. Poplars, willows, fig-mulberries, konars, cedars, cypresses, acacias, were common. Bananas, egg-plants, locust-trees, banyans, terebinths, the
