Paradoxornis flavirostris, Gould, in Proc. of Zool. Soc. Part IV. 1836. p. 17; and Magazine of Zool. and Bot. vol. eGo In the year 1836 I procured a single example of this anomalous bird, together with the Eurylaimus Dalhousie, and several other rare Himalayan species of a person who was not aware of the precise locality they were from. I believe that my specimen, which bas been since added to the collection of the Zoological Society, is quite unique, and that no other bird even approaching it in form has yet been discovered : in its soft lax plumage, rounded wing, and tail, and powerful foot and tarsi, it offers a striking resemblance to the members of the genus Pomatorhinus ; its arched and compressed bill, however, at once distinguishes it from that form: the situation of the nostrils, which are behind the bill, together with the stiff hairs which spring from the base of this organ, also serve to distinguish it from the Pomatorhini ; but a knowledge of its habits and the examination of other allied species, which in all probability are yet to be discovered, will alone enable the ornithologist to determine its real situation in the natural system. The figures are of the natural size. RST TTL
