308 Mr. O. Salvin's Visit to the 



America — one in the collection of the Smithsonian Institu- 

 tion, and one in that of Vassar College, Ponghkeepsie. The 

 former is labelled as having been obtained at Esmeraldas, 

 Ecuador; the latter was collected by Professor Orton at 

 Cliillo, in the Valley of Quito, on the western slope of the 

 volcano of Antisana, at an elevation of about 10,000 feet 

 above the sea. 



Chlorospingus axillaris, Lawr. Ann. Lye. N. Y. x. p. 395 

 (1874). 



The type of this species is quite a young bird, and is, I 

 have no doubt, a young male of Tachyphonus nitidis simus, 

 Salv., a few black feathers of the adult dress showing amongst 

 the general green plumage of the young bird. 



Chlorospingus brunneus, Lawr. Ann. Lye. N. Y. x. p. 395 



(1874). 



Through Mr. Lawrence's kindness I have carefully ex- 

 amined the type of this species, and find that it agrees per- 

 fectly with a specimen in Mr. Lawrence's collection ascribed 

 to the female of Tachyphonus clelattrii. This latter deter- 

 mination is, I have no doubt, correct, and the bird figured 

 in ' Exotic Ornithology ' (t. 34) as the female of T. clelattrii 

 belongs to some other species. This skin was obtained by 

 Eraser, and is that of a young bird, the proper determination 

 of which I am not at present able to decide. 



BUARREMON ASSIMILIS (BoisS.) ? 



I carefully examined the specimen attributed with doubt to 

 this species by Mr. Lawrence in his list of Costa- Rica birds 

 (Ann. Lye. N. Y. ix. p. 101), and found the differences between 

 it and a New-Granadan skin to be extremely slight. The 

 feathers round the bill are rubbed and wanting, giving the bill 

 the appearance of being larger than that of the southern B. 

 assimilis, it being in reality of hardly larger dimensions. The 

 difierence in the colour of the cheeks is due to the form of 

 the skin, the feathers being more compactly set. I think the 

 query may be removed and the species called B. assimilis.
