 it does comprise a large portion of the plumage of young males. 

 I have therefore placed the name among the synonyms. 

 The following is a list of the specimens I have examined : —

Hab. Trinidad {Boucard) ; Curayoa {Lawrence) . 



This species appears to be a native of Trinidad, and may

 quite sure, as I have not seen any thoroughly authenticated 

 specimens from the continent. It is very closely allied to 

 C. prasinus, Less., but may be distinguished by possessing a 

 scalloped tail, which that species has not. Individuals, how- 

 ever, vary slightly in the amount of the bifui'cation, which 

 in no case is of any considerable extent. Mr. Gould places 

 Lesson's name with two marks of interrogation, but uses it 

 nevertheless. Why there should be any doubt about it, is not 

 so easy to explain, because Lesson^s description is very clear, 

 and his plate answers well to it, with the exception of the 

 under tail-coverts having been left white, an evident omission 

 of the colourist, the only white mentioned in the description 

 being that of the anal region, a character common to all 

 the species of this group. If with a larger series of specimens
