86 CUVIER'S THICK-BILL. 



in the sub-genus Pachyrynchus, which name M. 

 Spix very improperly applies also to the genuine 

 PsarL I had long entertained the suspicion that 

 the female was the T. Fieillotii of the Illustrations 

 of Ornithology ; but I was only confirmed in this 

 belief by M. Natterer, who assured me, when in- 

 specting my collection, that such was truly the fact. 



In size, both sexes in our specimens are equal, 

 and they do not exceed that of a sparrow. In the 

 male the crown is of a deep and glossy black, which 

 is separated from the bill by a narrow frontal line

 outer edges ; the tail is much rounded ; the feathers 

 olive-green, margined at their tips with yellowish- 

 white ; the under plumage is white, with a broad 

 and bright band (undefined at the edges) across the 

 breast, the under wing-covers being of the same 

 colour.

 head, instead of being black, is of the same green 

 as the back ; the eyes are surrounded with a yel- 

 low ring ; while all those wing-covers which are 

 nearest to the carpus, or outer edge, are covered by 

 a spot of bright rufous. Between the first and 

 second primaries of the male is a spurious quill,
