Flagellata is an order of Protozoa characterized by the presence of flagellae (whip-like structures used for locomotion). In many flagellate forms, chlorophyll is present. These forms have been regarded by botanists as minute algae. This illustration shows 3 flagellates: 1) Ceratium Tripos, 2) Noctiluca, and 3) Euglena.

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.

A gadfly, or Bot-fly, that lays its eggs on horses. After these eggs hatch on the skin, the larvae bore into the skin and create tumors ('warbles') beneath it. When fully fed, they leave their host and drop to the ground, bury themselves, and, after pupation, emerge as flies. This illustration is enlarged, and also shows the larvae.

The Gadfly of the sheep lays its eggs in the nostrils of the sheep. There, the maggots hatch and live in the frontal sinuses until fully grown, they then drop to the ground and bury themselves. After pupation, they emerge as flies. This illustration is natural size and shows a Gadfly larvae.

This illustration shows a head of a Gems'bok. A Gems'bok (Oryx Gazella) is a species of South African antelope. It is a heavy, stout animal, about the size of a stag, with rough, reversed hair on the neck and along the ridge of the back; large pointed ears; and almost perfectly straight horns in the plane of the forehead, little diverging, and ringed for about half their length. These horns have been known to reach a length of 47 1/2 inches. The gems'bok was, at one point, close to extinction.
