curved bill. I received the examples I possess from Quito, but I 

 believe they were collected near the waters of the Upper Napo. 



Fregilus himalayanus, Gould. 



Plumage of the head aud the whole of the body, both above and 

 beneath, deep glossy black ; wings and tail black, glossed wdth purple 

 and green ; bill and feet coral-red ; nails black. 



Hab. The Himalayas. 



Remark. — This fine Chough differs so greatly in point of size from 

 the species killed in this country that I have no hesitation in de- 

 scribing it as distinct ; and that ornithologists may more clearly 

 perceive the great difference alluded to, I annex an accurate admea- 

 surement of male examples from India and Europe.

I may add that specimens from Italy and from Wales are precisely 

 alike in all their admeasurements. 



Prion magnirostris, Gould. 



Head, all the upper surface and sides of the chest blue-grey ; 

 lesser wing-coverts and the edge of the shoulder brown ; the remainder 

 of the wing blue-grey, deepening into slate-grey at the tips of the 

 inner primaries ; the outer primaries slaty black, fading into white 

 on the inner edge ; scapularies deepening into slate-grey near the 

 end, and tipped with pale grey ; tail very light grey, the centre fea- 

 thers tipped with blackish-brown ; chin, throat, centre of the breast, 

 abdomen, and under surface of the wing creamy white ; a faint wash 

 of blue on the lower part of the flanks aud the under tail-coverts ; 

 bill blue, deepening into black on the sides of the nostrils, at the tip 

 and along the side of the lower mandible ; irides brown, legs beau- 

 tiful light blue.

 wing 8 ; tail 4| ; tarsi 1|. 



Hab. Unknown. 



Remark. — As the name I have assigned to it implies, this species 

 differs from every other member of the genus in the extraordinary 

 size of its bill. In form and colouring it is precisely similar to the 

 other Priones, all of which are remarkably alike in these respects — 

 not so, however, in their bills, which consequently present the best 

 specific characters.
