44 PROCEEDIXGS OF THE NATIONAL MUSEUM vol. 74 



large series of specimens at Chapada, Matto Grogso, wliich liave 

 found their way into several different collections, and of late years 

 a good many have been collected in northern Venezuela. These 

 Venezuelan examples are precisely like those from Brazil and other 

 parts in all respects. The reappearance unchanged of this Brazilian 

 species in northern Venezuela, after parsing by the Amazon Valley, 

 gives it a discontinuous range which is hard to explain, but which is 

 paralleled in the case of a number of other birds. 



At first glance one is tempted to place this species in MyiotJdypis^ 

 but after going into the matter with some care I think that after all 

 it is better referred to Basileuterus. It differs from the type of 

 MywfhJypfs in its slenderer, more pointed bill, its longer outer- 

 most primary, and in its lack of a crest ; and agrees with BaslUutefus 

 in most respects save in style of coloration, and even here I find 

 some specimens showing traces of a median paler stripe on the fore- 

 head. The feet are a little stouter than in the majority of the species 

 of BasH^utei'tiS, but are not otherwise differently proportioned.
