- Aardvark
Of the order of toothless animals, the aardvark (Orycteropus aethiopicus), which occurs from the lowlands to the Woina-Deka, should be mentioned. The shy animal, with its smell and hearing, dwells in self-dug caves, characterized by lively leaps and a kangaroo-like position, supported by the powerful tail. It often goes only on the hind feet and nd sniffs the earth with the long, constantly moving nose, which resembles a pig's trunk, in order to look for ants. When it has discovered such a place, it begins to dig very skillfully and vigorously with the forefeet and push back the agitated Earth with the hind feet. For urine and dung, the aardvark digs a small pit, which is then carefully covered up again. In the building itself, it sleeps curled up lying on its side. Pursued, it hurries away in rapid bursts and burrows quickly, closing the tube behind it. - Dysderidæ
Dysdera Interrita A small family of spiders with only six eyes. They have also four breathing-holes in the front of the abdomen; but one pair leads to branched tubes instead of sacs. They are usually found under stones, with their legs drawn up close to their bodies, but can move very quickly when so inclined. Very few species are known, and none are common, in North America. At bottom of figure are the eyes as seen from in front. - Foot of Attus Mystaceus
In many spiders a brush of hairs takes the place of the middle claw, as in the jumping spiders. Spiders with these brushes on their feet can walk up a steep surface, or under a horizontal one, better than those who have three claws. - Foot of Epeira Vulgaris
The legs are used chiefly for running, jumping, and climbing; but the front pair serve often as feelers, being held up before the body while the spider walks steadily enough on the other six. One or both of the hinder legs are used to guide the thread in spinning; the spider at the same time walking or climbing about with the other six or seven. The legs are seven-jointed; and on the terminal joint are three claws ( A, B, C) and various hair and spines. - Locust
There has already been talk of the plague of the intestinal worms and their expulsion by Kusso; the higher standing insects occur in the highlands in large quantities only in the warmer season, but are driven back into the lower lying areas by the cold rains. The locusts , Amharic Anbasa, often cause great damage, as in the other Nile countries. - Mygale Hentzii
MYGALIDÆ This family includes the largest known spiders. The body is usually very hairy and dark-colored. Most species have only four spinnerets; and one pair of these are long, and are turned up behind the abdomen. They have four air-sacs under the front of the abdomen, instead of two, as other spiders. Their mandibles are very large, and work up and down, instead of sidewise. The eyes are collected together on the front of the head. They live only in warm countries. Specimens from South America are exhibited in every natural history museum. The figure represents Mygale Hentzii, a species living in Arizona and Texas. - Painted Dog
Painted dog ( Lycaon pictus ) A hyena-like predator, the "painted dog“( Lycaon pictus ) in groups; he attacks the flocks and wreaks havoc among them. The steppe landscapes are the real home of this sociable, up-and-out and murderous creature that never hunts alone. It gets its name from the large, dark spots on the light skins, where it is easy to distinguish. - Section of Epeira Vulgaris
Section of a spider to show the arrangement of the internal organs: a, b, upper and under lips of the mouth; c, c, the œsophagus; d, f, upper and under muscles of the sucking-stomach; e, stomach; g, g, ligaments attached to diaphragm under the stomach; J, lower nervous ganglion; k, upper ganglion; l, l, nerves to the legs and palpi; m, branches of the stomach; n, poison-gland; o, intestine; p, heart; R, air-sac; S, ovary; t, air-tube; u, spinning-glands. The intestine, o, continues backward through the abdomen to the anus, in the little knob behind the spinnerete. The brown mass which surrounds the intestine, and fills the abdomen above it, is supposed to be a secreting-organ discharging into the intestine at several points. - The common round-web spider, Epeira vulgaris of Hentz (Under Side)
The body is seen to be divided into two parts, connected only by the narrow joint, A, just behind the last pair of legs. The front half of the body, called the thorax, contains the stomach, the central part of the nervous system, and the large muscles which work the legs and jaws. The hinder half, the abdomen, contains the intestine, the breathing-organs, the principal circulating-vessels, the organs of reproduction, and the spinning-organs. Connected with the thorax are six pairs of limbs, four pairs of legs, B B B B, a pair of palpi, C, and a pair of mandibles, D. - Upper Side of Epeira Vulgaris
The head is not separated from the rest of the body, as in insects, but forms, with the thorax, one piece. On the front of the head are eight eyes, Q, which are differently arranged in different spiders. On the abdomen are several pairs of dark smooth spots, which mark the ends of muscles extending downward through the abdomen. The markings of this spider are very complicated. The spot on the middle of the front of the abdomen is a very common one, and, in some spiders, extends the whole length of the body. The waved lines on each side are also common, and, in long-bodied spiders, often form two bright-colored stripes, or rows of spots, running nearly straight the whole length of the abdomen.
