— ON CBSTRELATA FISHERI AND CB. DEFILIPPIANA. 

 5;, Bf ROB£RT RIDOIFAT. 



In the original description of (E. fisheri (these " Proceedings," vol. 5, 

 l^p. 656-658), I tabulated for purpose of comparison what appeared to 

 be the more striking diflerences between this species and CE. defiUppiana, 

 Gigl. & Salvad., the diagnostic characters of the latter beiug derived 

 from Mr. Salvin's description and colored plate in Rowley's "Ornitho- 

 logical Miscellany,'' part iv, p. 255, pi. xxxiii. The suggestion which I 

 there made to the effect that " some of the differential characters adduced 

 would (probably) not be found to hold good on actual examination of 

 specimens " proves correct, as I am able to discover by having the op- 

 portunity of comparing specimens of the two species. The specimen of 

 (E. defiUppiana now before me is a male, and is labeled in Jules Ver- 

 reaux's handwriting. It belongs to the collection of the American Mu- 

 seum of Natural History in New York City, and agrees very closely 

 with the description and jjlate cited above, except in some rather un- 

 important respects which will be aUuded to further on. The locality
