A complex anatomical view of the heart. RA is the right atrium, or auricle, which receives the deoxygenated blood by way of two superior vena cava (SVC) and one inferior vena cava (IVC). The blood passes through the right ventricle (RV) and is pumped up to the lungs via the pulmonary arteries (PA). At the lungs, the blood is reoxygenated and returns via the pulmonary vein (PV) and left atrium/auricle (LA). From there, the blood is passed to the left ventricle (LV) where the blood is pumped up through the systematic arch (SA) to the body. The systematic arch gives off a right innominate artery (INN), where the blood is then passed to the right and left carotid (C) and subclavian (SCL), where the blood goes to the head and arms respectively. It continues dorsally to the dorsal aorta (DA), which is the main artery that distributes blood to the whole body. TR is the windpipe, or trachea, BR is the bronchial tube that carries air to the lungs, and BV is a blood vessel on the wall of the heart.

Found in Oueensland and other parts of Australia, this lizard belongs to the family Agamidae. It reaches a length of about thirty-two inches, and receives its name from the presence of a large expansion of skin at either side of the neck. This frill is notched at the edge, has special supporting cartilages, and by means of muscles can be folded or expanded at will. The lizard walks upon its hind limbs, like the extinct Iguanodon, having the fore limbs hanging down. When at bay, it expands the frill to its fullest extent and opens the mouth wide, exposing its teeth. It inhabits sandy districts.

Also known as a Solan Goose (Sula bassana), the Gannet is a large marine bird which nests in scattered localities in most parts of the world. Its specific name refers to the fact that it has long been a denizen of Bass Rock -- a famous craggy islet on the coast of England. This bird also nests on Bird Rock in the gulf of St. Lawrence, and other species exist in the tropics. It belongs to the same sub-order as the cormorant, and may be recognized by the fact that, as in the latter, all four toes are united by a web. Its bill is long, strong, and compressed to a point. In adult life, the plumage is white, save for the black primaries and a buff patch on the head or neck; the young are dusky, and do not acquire the white plumage until their sixth year. Their nests contain only one egg.

The Great Crested Grebe (Lophæthyia cristata) is a fresh-water, migratory, diving bird of the family Podicipidæ. It has a duck-like body, brownish and white plumage, long neck, short wings, no tail, and large, flattened toes furnished with lobate membranes serving the purpose of webs. Most of its life is spent in fresh water lakes and ponds, but in winter and during migration, it often resorts to the sea. It is an excellent diver. The nest is made of rushes and other aquatic plants and usually floats on the water, being loosely anchored to weeds and grass. It is found in nearly all parts of Europe and Asia.

Guinea Fowl are the African representatives of the pheasants, from which they differ in that the plumage of both sexes is alike. The origin of the domesticated stock is <i>Numida meleagris</i>, from W. Africa. A number of other species occur in other parts of Africa. In the black guinea fowl (<i>Phasidus niger</i>), which ranges from Cape Lopez to Loango, spurs are present in the male as in pheasants. Guinea fowl are nearly all gregarious, are ground feeders, and roost in trees. Most species seek to escape danger by running rather than by flying. As in the turkeys, parts of the head and neck are without feathers, and these bare patches are often highly colored.

The Jumping Mouse (Zapus hudsonius) is a N. American, jerboa-like mouse, with long hind legs, a very long tail, and five complete toes on the hind foot. It is warmly reddish above, white on the lower parts, and progresses, when alarmed, by a series of rapid leaps, each of several yards, when in haste. it dwells in open, grassy places, skulking about under the herbage and feeding mostly on grass seeds; there it places its nest (a hollow ball of grass) in some small hole or burrow, and spends the cold months in a long hibernation.
