30? and 31 ? In the catalogue of Dr. Royle's birds procured at Saha- 

 runpore and the neighbouring districts of the Himalaya, G. leucotophos 

 is noticed as inhabiting the lower hills, and two other species are 

 mentioned of which I have seen no description ; viz. melanocephalus, 

 on the hills, and striatus, met with in the Kheree Pass. Whether these 

 be distinct from all the foregoing, remains to be ascertained.* 



* In a list of specimens now on their way from Mr. Hodgson, I find three species 

 mentioned, by the names leucopophlus (Quaere leucolophos ) , erythropterus, and 

 subunicolor ; this last, with setafer and others, constituting Mr. Hodgson's division 

 Trochalopteron, the propriety of adopting which name will depend on whether Mr. 

 Swainson's Crateropus Reinwardii be considered admissible into the group, in which 

 case it must bear the appellation Crateropus. 



The specimens adverted to have since arrived, but Tr. leucopophlus (?) and 

 erythropterus are not among them; and of Tr. subunicolor, a nestling specimen only 

 is sent, of a species nearly allied to Tr. erythrocepkalus, chrysopterus, and affinis, 

 especially to the latter, but having a shorter and thicker bill than in that bird. In a 

 nestling example of Tr. chrysopterus before me, the lunate black spots on the breast 

 of the adult do not exist, beyond a mere trace of them on the sides of the breast; being 

 the contrary of what is observable in the Thrush and various other groups, wherein 

 the young are more mottled than the adults. Length of the immature subunicolor 

 about nine inches, of the wing three inches and a half, and tail four inches; bill to 

 gape seven-eighths of an inch, and tarse an inch and three-eighths. General colour 

 greenish olive-brown, tinged with dusky on the head, and brighter greenish on the 

 tertiaries and tail, the latter having a slight wash of aureous; exterior tail-feathers 

 dusky with white tips, the latter successively increasing to the outermost ; edges of 

 primaries bright golden-yellow, as in affinis, but the narrow exterior edge of the outer 

 primaries greyish beyond their emargination ; lower-parts dull olive-brown: the dorsal 

 plumage is slightly margined with black, in the adults probably as much so as in 

 squamatus ; and two or three new feathers growing on the breast are whitish towards 

 the tip with a dusky margin, indicating that the under-parts of the adult would be 

 thus mottled : bill dusky above, the under mandible yellowish except at tip ; and feet 

 brown. Nepal.
