18/8.] COLLECTED BY PROF. STEERE IN SOUTH AMERICA. 141 



Obs. Affinis 0. richardsoni, sed colore corporis superioris palli- 

 diore viridi, nucha cyanea, et pectore limonaceo-flavo sane diversus. 



Of this beautiful new Capito, which we have the pleasure of dedi- 

 to its discoverer, there is, unfortunately, but one specimen in the 

 collection, now in the Museum of the University of Michigan. The 

 species is closely allied in form and disposition of colour to C. 

 richardsoni, but may be distinguished by the differences pointed out 

 above. 



Among some birds lately sent by Mr. G. N. Lawrence of New 

 York to Sclater for determination, we find an imperfect skin, evi- 

 dently of the same species. It was obtained by Walter S. Church 

 at the " head-waters of the Huallaga, " during his journey up that 

 river, and belongs to the collection of the Smithsonian Institution. 



19. COLUMBULA CAMPESTRIS (Spix). 



Five specimens of this species are in Prof. Steere's collection, all 

 of them obtained at Arare, in the island of Marajo. The species, 

 though long ago described by Spix, has seldom been met with by 

 more recent collectors. Natterer, however, secured several examples, 

 mostly in the Brazilian provinces of Goiaz and Cuyaba. 



20. Limosa fedoa (Linn.). 



Limosa fedoa, Scl. & Salv. Nomencl. p. 146. 



One of two specimens of this Godwit was obtained at Santa Rosa, 

 Ecuador ; the other is without precise locality. Though the allied 

 L. hudsonica ranges throughout South America, this species, so far 

 as we know, has not hitherto been noticed south of Central America. 



21. Xema sabinii, J. Sab. 



Xema sabinii, Coues, Birds of the North-west, p. 660. 



Prof. Steere's collection contains a single example of the Fork- 

 tailed Gull, shot at Tumbez, Western Peru. This is the first instance 

 of the occurrence of the species in any thing like so southern a locality, 

 the limit of its southern range having been hitherto supposed to be 

 the Great Salt Lake, Utah. The specimen is in adult winter plumage, 

 the head being white, the nape and back of the neck ashy black, 

 each feather with a very narrow white margin ; the mantle is pure 

 grey, and the primaries coloured as in the adult bird.

 cervice posticd murino-brunned ; pileo nigro, ochraceo brunneo
