essentially topotypical. This species is evidently specifically distinct from 

 P. cristata, incjeed appears to be nearer P. jaquagu Spix (= boliviana Rich.). 

 It obviously, therefore, is not the same as Penelope oequatorialis Salvad. & 

 Fest. which our material shows to be inseparable from true cristata. The dis- 

 tinguishing characters of P. perspicax are the coppery auburn of the exposed 

 surfaces of the inner wing-quills and the grayish lateral margins of the hind- 

 neck and f oreback. In both these respects it differs markedly from cristata; 

 but in the last-named character it agrees with P. jacquagu. The latter, how- 

 ever, has the wings olive as in cristata, but differs from both cristata and per- 

 spicax in the extension of the reddish brown underparts forward to the chest.
