This singular type is, I now think, on the "whole best placed 

 here next to Heteropelma, with which it closely agrees in the 

 structure of the foot and bill. It is remarkable for having the 

 fourth primary attenuated and curved slightly outwards in the 

 male sex. 



The very peculiar nestling of Ptilochloris has been described and 

 figured by Mr. Salvin and myself, P. Z. S. 1880, p. 158.

It is possible that there may be a closely allied representative of 

 this form in Colombia, distinguished by its rather smaller size and 

 yellow breast. If this be so, the term remiyialis of Lafresnaye
