species of Birds from Brazil. 141 



to one and the same species^ which seems distributed over a 

 large area, being found in New Granada,, Venezuela, Guiana, 

 Eastern Ecuador, Brazil, and Bolivia, and for which the 

 oldest name seems to be " tuberculifer, Lafr. & d'Orb.'^ 

 This species differs from the true M. nigriceps, Scl. (from 

 Western Ecuador and Peru), in its sooty-black or brownish 

 cap (which is pure black in M. nir/riceps] , besides having other 

 minor points of distinction. Both species have always been 

 unjted under the name of M. nigricejjs, Scl. ; but they must 

 certainly be kept apart.

 Hah. Bahia, Brasilia. Typical specimen in my collection 

 (no. 6484). It was purchased from Mr. Edward Gerrard, 

 Jun., in London, and bears a museum label, on the top of 

 which the letters W. W. S. are printed*. There is also written 

 on the label " Xiphocolaptes albicollis, V., Brazil,^' number 

 2384 j^"* but X. albicollis has, of course, nothing to do with it. 

 The specimen is of the usual Bahia make.] 



Obs. D. valido, Tschudi, proximus, sed differt pileo in fundo 

 unicolori nigrescenti-brunneo, striis ochraceis latioribus (in 



* Perhaps one of my English friends could tell me what museum is 

 meant by the letters W. W. S. [The initials W. W. S. mean " W. Wilson 

 Saunders," whose collection of birds was purchased, we believe, by Mr. 



E. Gerrard, Jun. — Edd.]
