URUBITINGA. LEUCOPTERXIS. 249 



The McConnell collection does not possess an example of: this 

 species, and the description of the male is taten from a specimen in 

 the British Museum, collected by Mrs. D. W. Smith on the Island 

 of St. Vincent, February 12th, 1880 — Salvin-Godman collection. 



Adult female. Similar to the adult male. Wing 370 mm. 



Breeding-season. Unknown in British Guiana. 



Nest. "In tall trees" (Schomburr/k). 



Eggs. Undescribed from British Guiana. 



Range in British Guiana. Near the mouth of the Waini River 

 (^Schomburgk). 



Extralimital Range. Brazil, Trinidad, Cuba, St. Vincent, and 

 Central America. 



Habits. According- to Schomburgk (Reis. Guinn. iii. p. 740) 

 this bird is distributed over the -whole of British Guiana, and has 

 the same habits as those of the previous s[)ecies, U. urubitinga. 

 He also found it numerous in the damp woods near the mouth of 

 the River AVaini. If there is a Savanna fire this bird and the 

 preceding species are there immediatel}-, preying on the reptiles 

 and quadrupeds that are escaping from the fire. Schomburgk 

 says that he often saw its nest on the tall trees. 



Mr, J. J. Quelch remarks on this species (Timehri (2), vi. 

 pp. 157, 158): — '"'Another species of this genus, U. antJiracina, 

 has been recorded by Prof. Cabanis from the Colony, and has, 

 apparently on this authority, since the biid has not been nut with 

 by Whitely, been included by Salvin in his revised list. It has 

 been included in the foregoiuo; list of the hawks of British Guiana 

 on the same authority, though the species does not occur in our 

 Museum collection, nor indeed has ever been met with, or heard 

 of, by me in any part of the Colon}-."
