582 MESSRS. SCLATER AND SALVIN ON [May 23, 



150. Galbula albirostris, Lath. 

 Guia, Rio Negro. 



lol. Galbula cyaneicollis, Cassin. 

 Capim River. 



152. Galbula leucogastra, Vieill. 

 Guia. 



153. Urogalba paradisea (Linn.). 

 North bank of the Amazons. 



154. Urogalba amazonum, Sclater, P. Z. S. 1855, p. 14. 



Para. 



After some consideration we feel bound to resuscitate this species, 

 which Sclater, after having described it, was persuaded by Von Pelzeln 

 to reunite to the preceding. It is certainly readily distinguishable 

 by its much larger size, the hoary terminations of the head-feathers, 

 the less amount of black on the chin, and the greater extent of white 

 on the throat below, and requires a name. 



155. Brack YGALBA inornata, Sclater. 

 Baiao, Rio Tocantins. 



4-156. Jacamerops grandis (Gm.). 



Capim River and vicinity of Barra, examples of both sexes. 



" This bird has more the habits of the Trogons than of the true 

 Galbulce. While the latter are always found on the outskirts of the 

 forest, the Jacamerops keeps rather to the gloom, where it sits on 

 boughs hanging over the forest and captures insects." — A. W. 



Fam. BuccoNiDJi. 



157. Bucco collaris. Lath. 

 Lower Amazons. 



158. Bucco hyperrhynchus, Bp. 



Para. Above Barra, on the south bank of the Amazons, Mr. Wal- 

 lace obtained the Peruvian species {B. napensis, Sclater). The loca- 

 lity of " Upper Amazons," comnionly attributed to this species, is 

 very probably erroneous. 



159. Bucco TAMATIA, Gm. 



Three examples, without exact localities, agree with the Cayenne 

 bird. A fourth, from the Capim River, has the spots on the belly 

 crowded as in B, pulmentum of the Upper Amazons ; but the throat 

 is as dark as in the Cayenne bird, not pale as in B. pulmentum. 



-/~160. Bucco TECTUS, Bodd. 



Para. Agrees with Cayenne specimens.
