M. Salle's collection coutains four examples of this interesting bird, 

 wliich has never j)reviously conie uiider my uotice. One marked as 

 a female has the bill rather longer than the others, but does not 

 otherwise difFer from them. It may be at once distinguished from 

 tbe Biazilian (S. caudacutus (to wbich it sbows great general resem- 

 blance) by its smaller size. Hartlaub's S. fuscus (R. Z. 1844, p. 3/0) 

 seems to be larger, and differently coloured.

 specimens of C. americana,

This Mexican species nmch resembles in colouring a Bogota bird 

 in my collection, which I somewhat doubtfully refer to S. griseicollis, 

 Lafr., but differs from it in having the lower parts cinereous and not 

 white.
