236 CYMBIRHYNCHUS. 



deep as the upper, the gonyx taking an angulated 

 ascending curve ; the rictus is defended by three or 

 four long bristles ; the bill is not only powerful in 

 its general character, but it has, something like 

 that of the toucans, a thickened margin. Another 

 peculiarity is to be found in the nostrils, which are 

 perfectly naked, and situated towards the middle of 

 the bill ; the aperture is oval, and without any rim 

 or membrane ; the tail, although graduated, is of 

 the average length of ordinary birds ; but, in other 

 respects, the structure accords with the remaining 

 species.
