Mitrospingus Ridgway, Auk, xv, no. 3, July, 1898, 225. (Type, Tachyphonus 

 cassini Lawrence. ) 



Nearest to Eticometis, but bill much longer (nearly as long as head), 

 nostril very different, wing more rounded, tarsi relatively longer, 

 claws stronger, occipital feathers very short (instead of the reverse), 

 and style of coloration very different. 



Exposed culmen three-fourths as long as tarsus, or more, gently 

 convex except terminally, where strongly decurved; gonys decidedly 

 shorter than length of maxilla from nostril, nearly straight; maxillary 

 tomium slightly concave, decidedly but gradually deflected basally; 

 slightly notched subterminally; mandibular tomium nearly straight to 

 near base where gently deflected; depth of bill at base decidedly less 

 than half the length of exposed culmen, not much greater than basal 

 width. Nostril exposed, narrow, longitudinal, with very broad supe- 

 rior membrane. Rictal bristles not obvious. Wing moderate (about 



' Four specimens, two from Chiriqui, two from Veragua; one of the latter not 

 sexed, but, being the larger of the two, doubtless a male. 

 ^Two specimens, from Volcan de Chiriqui (Caribbean slope).
