The Cereopsis, or Cerefaced Goose, of New Holland, is a Palmiped genus, about the size of a common goose, which, in general appearance, he resembles, except that his legs are longer, averaging from two and a half to three feet. The plumage is of a dingy gray. A large patch of dull white occupies the top of the head; the quill-feathers, both of the wings and tail, are of a dusty black. His voice has a hoarse deep clang, like that of a storm-bell. He usually weighs from seven to ten pounds, and makes an excellent dish for an Australian Christmas table. Specimens may be seen both in the Zoological Gardens of London and Paris. [Illustration: APTERYX AUSTRALIS.] The _Apteryx Australis_, or Wingless Emu--the _Kiwi_ of the New Zealanders--somewhat resembles a penguin in form, and stands about two feet in height. The only living specimen in Europe lives, I believe, in the London Zoological Gardens. As it does not appear to rank, in scientific classification, with any other family or genus, naturalists have erected it into a distinct order--the _Nullipennes_, or Wingless. The wings of the apteryx are literally rudiments; a mere stump, terminated by a hook. None of his bones are hollow; he has no abdominal air-cells; his feathers have no accessory plume; his feet have a short and elevated hind-toe; his eyes are small; he feeds on insects; and his habits are nocturnal. He is a bird of great physical power, and runs with ostrich-like swiftness; taking refuge, when pursued, in burrows, hollow trees, and the clefts of the rocks. His cry resembles a loud whistle, and the natives entrap the bird by imitating it. When the female has been taken, the male is easily caught, owing to his reluctance to leave her. He will, however, defend himself vigorously with his spurs. The Erpetological Fauna of Australia, and, in general, of Oceania, is very poor, and comprehends no great species. I may notice a genus of lizards, the Chlamydosaurus, discovered by Allan Cunningham, the naturalist attached to Captain King's expedition, about 1820. It measures about seventeen inches in length, of which twelve inches are apportioned to the tail; is of a yellowish-brown colour; has a large head, with prominent eyes; and a membraneous ruff or tippet round its neck, covering its shoulders, and when expanded spreading about five inches in the form of an open umbrella. If attacked or terrified, it elevates the frill or ruff and makes for a tree; where, if overtaken, it throws itself upon a stem, raising its head and chest as high as it can upon the fore-legs, then doubling its tail underneath the body, and displaying a very formidable set of teeth from the concavity of its large frill, it boldly faces any opponent, biting fiercely whatever is presented to it, and even venturing so far in its rage as to fairly make a fierce charge at its enemy.
