210 Messrs. O. Salvin cmd F. DuCane Godman on 



Mr. Whitely sent us a pair of this species^ and also a single 

 example of A. uropygialis (Cab. in Seliomb. Reise n. Guiana^ 

 iii. p. 686) , which we also believe to be a distinct species. Along 

 with these are several specimens of a third species^ which so 



I much resembles A. sclateri that we hesitate to separate it. 



f In Guiana^ too, A. spadiceiis (Gm.) is found, and also A. 



thamnophiloides (Cab. in Schomb. Guiana, iii. p. 686) ; so that 

 in this region we find no less than five species of Attila, 

 all more or less distinct !

 '^ Mus. nostr. 



Obs. D. valido afiinis, sed interscapulio fuscescentiore et 

 nigro indistincte transfasciato, striis quoque capitis angusti- 

 oribus, subtus abdominis fasciis totis integris nee disjunctis 

 distiuguendus. 



This bird is probably the representative in Guiana of the 

 Andean D. validus (Tsch.), but seems sufficiently distinct for 

 recognition. Mr. Whitely obtained two specimens of it, a 

 i male and a female, both at Camacusa.
