secured by Delattre at Buenaventura, in the Bay of Choco. 

 Birds from Western Ecuador are absolutely similai-. 



Skins from Costa Rica (Oarrillo etc.) are lai'ger, with a longer 

 and more slender bill ; the males are of a duller, more brownish 

 black, and have the vertical crest somewhat deeper orange. 

 They are perhaps subspecifically separable. The locality ' Pasto ' * 

 is, no doubt, incorrect, for T. delatrii is found only in the 

 lowlands and foot-hills.

 southwards to N,W, Ecuador, whence Mr, Rosenberg's collectors 

 have sent many specimens t. It is an inhabitant of the humid 

 forests of the lowlands and foot-hills, up to about 2000 feet.
