ATTILA. 287 



Total length 165 mm., exposed culmen 18, wing 85, tail 62, 

 tarsus 23. 



The specimen described was collected on the Lower Mazaruni 

 River by Mr. McCbnnell during his expedition to Mount Roraima 

 in 1898, and is in similar plumage to that described by Oabanis 

 in Schomb. Reis. Guian. iii. p. 6^6. 



Adult female. Similar to the adult male but rather smaller. 

 Wing 82 mm. 



Although I have examined a fairly large series (between twenty 

 and thirt^y individuals), the number of sexed and dated specimens 

 is insufficient to arrive at a satisfactory conclusion in regard to 

 the sequence of plumages. It appears to me desirable, therefore, 

 to uphold the two species that have been described from tho 

 colony until the time when there is sufficient material to solve 

 the problem ; but from the variety of plumages exhibited in this 

 series, I should not be surprised to learn that there is a third 

 species even, as there are two specimens in the McConuell 

 collection which are quite different from the rest.

When Brabourne & Chubb compiled their ' List of the Birds of 

 South America ' they followed some of the previous authors in 

 suj)posing that Lesson's bird — Attlla hrasiliensis — came from 

 Cayenne, not from " Brasil " as he himself stated. On looking 

 u)i tho literature again, however, I see no direct evidence why 

 Jje^:son's locality should be made to read C^iyenne, as liis original 

 description !ip[)ears to a[)ply ecpially well to JMusricajni uroj'i/giala 

 Wied,:iiid I notice, too, that the late Dr. P. L. Sclatcr was of that 

 ojiinioM also, as he has marked one of the specimens in tho 

 iiritish jMii'^eum from South-East l>razil, which was previously in 

 his collection, " xl/^i/a hrasiliensis com|Kired with typo in Miis.
