When my drawing of this species was made, I had only seen the male; since then Captain Sturt has presented me with a female, which differs from the opposite sex in the absence of the black markings of the throat, breast and wings, which parts are brownish grey. Genus OREOCINCLA, _Gould_. _Bill_ as long, or longer than the head, slightly incurved, compressed laterally; the tip of the upper mandible overhanging the under; notch considerably removed from the tip; _tomia_ or cutting edges sharp; _nostrils_ basal, oval; _rictus_ beset with a few short hairs; _wings_ moderately long and rigid, first quill very short, the fourth and fifth nearly equal, and the longest; _tail_ rather short and square, the feathers rigid, and running to a point exteriorly; _tarsi_ moderate, scales entire; _toes_ slender, particularly the hinder one; outer toes nearly equal, but the inner one rather the shortest; _general plumage_ silky to the touch; the _rump-feathers_ spinous, as in _Ceblepyris_ and _Graucalus_. Species of this genus inhabit India, the Indian Islands and Australia, in which latter country, although much difference in size is observable in specimens from different localities, I believe only one exists. It is decidedly a brush bird, and has many habits in common with the typical Thrushes, but is more shy and retiring. 257. Oreocincla lunulata Vol. IV. Pl. 7. Family PARADISEIDÆ, _G. R. Gray_. I certainly consider the accounts I have given of the extraordinary habits of the _Chlamyderæ_ and _Ptilonorhynchi_ as some of the most valuable and interesting portions of my work, and however incredible they may appear I am happy to say they have been fully confirmed by other observers. Genus CHLAMYDERA, _Gould_. Generic characters. _Bill_ moderate, _culmen_ elevated, and arched to the tip which is emarginated, compressed on the sides; _gonys_ slightly advancing upwards; _nostrils_ basal, lateral, exposed, rounded, and pierced in a membrane; _wings_ long and pointed, first primary short, second primary shorter than the third and fourth, which are equal, and the longest; _tail_ long and slightly rounded; _tarsi_ robust, defended anteriorly with broad scuta; _toes_ long and strong; outer toe longer than the inner, hind-toe long and robust; _claws_ long, curved, and acute. 258. Chlamydera maculata, _Gould_ Vol. IV. Pl. 8. Inhabits South Australia, New South Wales, and according to Mr. Gilbert’s Journal of his overland journey to Port Essington, the intertropical regions of the east coast.
