- Senecio stapeliaeformis
Senecio stapeliaeformis - Sense-Organs susceptible to Pressure
All are formed on essentially the same plan; a fibrous capsule invests a group of epithelial cells amongst which a nerve ramifies. The simplest form is known as a Grandry’s corpuscle-a nerve ending in one or two plates between two or three epithelial cells. These organs are found in great numbers in the bills of aquatic birds. If a duck is watched whilst it is gobbling mud at the margin of a pond, it will be seen to have a remarkable capacity for discriminating between the shells of small snails, which it can crush, and stones, which it needs to drop from its bill. Its bill is also provided with small Pacinian corpuscles. - Sepsis violacea; puparium and adult
Sepsis violacea; puparium and adult - Seventeen-year Cicada
Adult, Chrysalis-Case, Pupa, Entrances to Burrows and Egg-Nests. In the winged state Cicada septendecim is of a black color, with transparent wings and wing-covers, the thick anterior edge and veins of which being orange-red. Near the tips of the latter there is a dusky zig-zag line which resembles in shape the letter W. The eyes, when living, are also red, while the legs are a dull orange, which color is conspicuous along the edges of the rings of the body. The wings expand from two and a half to three and a quarter inches. - Shady and sheltered Dell

M, mouth; S, ciliated groove; T, tentacles. Each tentacle is perforated by a single large aperture. A fact of some importance that supports this hypothesis, as regards some parts of the ocean at least, is presented by the sea-anemones. Many of the shallow-water Actinians are known to possess minute slits in the tentacles and disc, affording a free communication between the general body cavity or cœlenteron and the exterior. In many deep-sea forms the tentacles are considerably shorter and the apertures larger than they are in shallow-water forms. It is difficult to believe that such forms, perforated by, comparatively speaking, large holes, could manage to live in rapidly flowing water, for if they did so they would soon be smothered by the fine mud that composes the floor of all the deep seas. In fact anemones of the type presented by such forms as Sicyonis crassa are only fitted for existence in sluggish or still water. - Side striped jackel
Side striped jackel - Simulium venustum
The Simuliidæ, or black flies, are small, dark, or black flies, with a stout body and a hump-back appearance. The antennæ are short but eleven-segmented, the wings broad, without scales or hairs, and with the anterior veins stout but the others very weak. The mouth-parts are fitted for biting. - Sitting dog

These skeletons of the five living genera of anthropomorpha are reduced to a common size, in order to show better the relative proportions of the various parts. The human skeleton is 1/20 th natural size, the gorilla 1/18 th, the chimpanzee 1/7 th, the orang 1/7 th, the gibbon 1/9 th. Young specimens of the chimpanzee and orang have been selected, because they approach nearer to man than the adult. No one of the living anthropoid apes is nearest to man in all respects; this cannot be said of either of the African (gorilla and chimpanzee) or the Asiatic (orang and gibbon). This anatomic fact is explained phylogenetically on the ground that none of them are direct ancestors of man; they represent divergent branches of the stem, of which man is the crown. However, the small gibbon is nearest related to the hypothetical common ancestor of all the anthropomorpha to which we give the name of Prothylobates. - Skeletons of the Gibbon, Orang, Chimpanzee, Gorilla, Man

- Skylark, and young ones
The fact that many young birds which are quite helpless are now reared in nurseries on the ground, as in the case of young skylarks, is a fact of interest; for it shows that the parents have chosen this nesting site comparatively recently, and are of course unable to lay large eggs, which shall produce active young, like young chickens, at will. They have acquired the habit, so to speak, of laying small eggs, and cannot alter it by changing their nesting-place. - Slate-colored Junco
Slate-colored Junco The sparrow-size Slate-colored Junco or the “snowbird,” as he frequently is called, is only a winter visitor in most areas. But what a welcome guest he is! The white belly and outer tail feathers add distinctive marks to his slate-gray plumage. The bill is pinkish white. Females and immature birds are duller and sometimes show a pinkish-brown tinge on their backs and sides. Juncos can be found around weed patches, hedges or sheltered corners of fields, where they spend much time in feeding on weed or grass seeds which provide their winter diet. Even fallen seeds are not overlooked for these birds do much of their feeding on the ground. They sleep in evergreens, sheds or other protected areas which shelter them from the cold and snow. They often visit feeders for small seeds provided by bird lovers. Their notes are hard to describe but have a musical smacking or clinking note or series of notes which once learned, are easily remembered. Their song is a series of chipping notes much like those of a Chipping Sparrow, but with more variation and more of a musical quality. This song is heard when the first warm days of spring arrive. They nest in either mountainous or northern regions for they enjoy cool climates. - Sleeping Bat

Snow Goose This medium-size goose is the most abundant member of the family and can be identified by white plumage and black wing tips. He is often called “wavy,” in the northern part of his range, while southern hunters refer to him as a “white brant.” His Latin name describes him as “a goose beyond the north wind.” We see him only as a migrant, either going to nesting grounds in Northern Canada or returning to his winter home on the coast of Louisiana and Texas. A somewhat larger relative known as the Greater Snow Goose, nests in Northern Greenland and winters along our Atlantic coast. This bird feeds on roots and bulbs of water plants found in his wintering area. Grasses, grains or other vegetation bring huge flocks where they can be seen grazing like tame geese. Feeding flocks are not welcome to the wheat grower who has fields near lakes which are used as resting places for migrating birds. - Snowy Egret
Leucophoyx thula Like ghosts from a bloody past, Snowy Egrets have returned to add their beauty to American bird life. Woman’s vanity and man’s desire for money once brought these beautiful herons almost to the point of extinction. The dainty recurved plumes, which formed a part of the breeding plumage of the birds, were known as “cross aigrettes,” when they were sold by milliners. Women bought, men slaughtered, and egrets died, not only for the plumes; but the nestlings starved after the adults were killed. Plume hunters have departed and the birds are now found in their favorite swamps. This bird has a length of 20 to 25 inches, white with black bill and legs. The feet are yellow, giving it the nickname of “the bird with the golden slippers.” The young of the Little Blue Heron are also white but have greenish legs, while the bill is 2-tone, blue with black tip. The American Egret is much larger and shows a yellow bill. - Soggy cat

- Song Sparrow
Song Sparrow Song Sparrows literally sang themselves into a name, for few birds sing so persistently. To Thoreau these birds seemed to say: “Maids! maids! maids! hang up your teakettle-ettle-ettle.” To you it may sound differently, but you still will hear the sharp notes with which he starts his song. These are on the same pitch with a slight pause between each note. From there, the song is variable and may contain trills or assorted notes on various pitches. One bird may produce several different songs. These birds prefer brushy or weedy areas near water but may nest near your home if a bird bath is handy. No other bird seems to take as much pleasure from bathing. - Southern European Vultures
- Sparrow Hawk
Sparrow Hawk This little falcon, about the size of a Robin, is also known as Kestrel. Calling him a Sparrow-hawk is misleading, for insects and spiders, along with a generous portion of mice, go to make up his daily fare. Grasshoppers seem to be a special delicacy. Like other birds, he feeds on whatever is available. In cities, this includes English Sparrows. The smallest of the hawk family can be found along highways where he uses telephone poles, wires or dead trees, while scanning the fields and fence rows for prey. Dressed in colorful plumage with spotted breast, slate-blue wings, red-brown back and tail, with head showing 2 black lines and a dot, he easily is seen and readily identified. The female is slightly larger, shows more banding on the tail and lacks the blue wings, hers being browner. - Sparrowhawk
