Specimens from the Caura Valley in the Munich xAInseam differ by their more 

 sandy (less greyish) back, darker pilenm, and slightly more yellowish (less greyish) 

 under parts, bnt others from the same region in the Tring Museum are scarcely 

 distinguishable from the typical Madeira birds. 



In '_'. littoralis there is a marked difference in size between the sexes, the males 

 being considerably larger.

Agrees with one of Sjiix's typical specimens in the Munich Museum, but is 

 rather more blackish above, and has brownish white apical margins to the greater 

 upper wing-coverts. The scapulars are blackish brown like the back ; the rump is 

 crossed by a narrow white band ; the rectrices are uniform blackish without white 

 apical edges, which are always well defined iu the allied F. pica (Bodd.). 



F. albirenter has a wide range in Brazil, Argentine, etc.

Agrees with an examjile from I'erico, Upper Orinoco (Cherrie coll.), which I 

 had previously compared with the type in the 15ritish Blusenm. The small size and 

 glossy black plumage together with the narrow, acuminate, three outer primaries 

 distingnish this species among its congeners. It bears a striking likeness to 

 Aeiio/jipo atrohitt'ns, but on closer examination the two birds are seen to be quite 

 distinct. K. pusillus has shorter wings, a much larger, ditferently coloured bill, 

 numerous strong rictal bristles, etc. 



The type, obtained by Wallace, remained unique until Cherrie obtained two
