"'This species resembles C. aura, Linu., in the shape of the bill and 

 nostrils, and in having the tail rounded, but differs from it not only in 

 size, hut the feathers extend upwards on the back of the necJcand lie flat in- 

 stead of forming a ruff; the plumage of the specimen now described is 

 black, none of the feathers having pale margins^ as is commonly the casein 

 specimens of C. aura ; the shafts of the primaries are clear white, and 

 the head is ujore entirely destitute of downy feathers. The tarsi are 

 longer and more slender. 



"'The head of C. hurrovianus is quite smooth, in which, as in other 

 respects, it is very different from C. atratus, Wilson. 



"'This new species was obtained in the vicinity of Vera Cruz, by the 

 late N. Burrough, M. D., in honor of whom 1 have named it, as a slight 

 acknowledgment of his very valuable services to natural history and to 

 this academy.'" 



Having recently, through the courtesy of the officers of the Philadel- 

 phia Academy of Natural Sciences, been able to make an actual com- 

 parison between the type of C. hurrovianus and one of the typical 

 specimens of G. urubitinga^ Pelz. (ex batterer) — one of Natterer's speci- 

 mens, in fact, obtained from the Vienna Museum— I am now able to 

 speak with more confidence in the matter. It only needs to be said 

 that the two specimens are as much alike as it is possible for two ex- 

 amples of the same species to be. They are identical in every character 

 which distinguishes C. urubitinga from C. aura, and there cannot be 

 the slightest question of their specific identity. (J. uruhltingu., Pelzeln, 

 therefore becomes a synonym of C. hurrovianus, Cassin,* the principal 

 references being as follows: •
