3.'50 X. V. Pelzelii on Birds from Spanish Guiana 



TiNNUNCULUS SPAIIVERIUS (L.). 

 ASTURINA MAGNIROSTRIS (Gm.). 



Nauclerus furcatus (L.). El Tijerete. 



Athene ferruginea (Pr. Neuw.). Cabrilla. 



Athene minutissima (Pr. Neuw.). 

 Two very dark-coloured specimens. 



Hemiprocne zonaris (Shaw), var. albicincta. 



Hemiprocne albicincta, Cahanis, Journ. f. Orn. 1862, p. 165 

 (Giiiana, Mexico). 



Ch(Btura zonaris, Sclater, P. Z. S. 1865, p. 609. 



The specimen received from H. Hodek is distinguished by 

 the character mentioned by Prof. Cabanis, i. e. inferior size 

 and greater breadth of the upper part of the collar. The black 

 of the body, especially on the upperside, is glossed with 

 green, as in the oldest individuals of the common H. zonaris 

 from South Brazil. Long. al. 7" 5'", caudse 2" 7'", 



A Jamaican specimen, received from Mr. Sclater in ex- 

 change, agrees well with that from H. Hodek ; its plumage is 

 only a little less glossy. 



It seems to me probable that H. albicincta is separable from 

 zonaris, at least as a northern race. 



Stelgidopteryx ruficollis (Vieill.). 



Bucco RADiATus, Sclatcr. 



Heleodytes bicolor, sp. nov. Carraquero. 



1 Heleodytes griseus , Baird (nee Swains.), Rev. Am. Birds,
