According to the writer's views Basileuterus rufifrons (Swainson) 

 and Basileuterus delattrii Bonaparte represent two specific types, with 

 the latter of which Basileuterus mesochrysus Sclater is of course con- 

 specific. 



Nos. 42,273-4 (June 19) are in juvenal dress, in which state the 

 whole pileum is olivaceous, duller than the back, the superciliary stripe 

 merely . indicated. Other birds dated August 16 to 18 are in various 

 stages of the postnuptial moult. Adults vary somewhat as regards 

 the extent of the rufous on the pileum and the width of the grayish 

 color on the hindneck. 



A species which is rarely seen outside of the " dry forest " of the 

 foothills between 800 feet and 3,000 feet, but commoner above 

 1,200 feet, being thus essentially characteristic of the middle part of 

 the Tropical Zone. In habits it is much like B. cabanisi iudiguus.

Fifteen specimens: Bonda(?), Las Nubes, Onaca, La Tigrera, Las 

 Vegas, and Minca. 



Basileuterus cabanisi was described from specimens taken at San 

 Esteban and Puerto Cabello, Venezuela. Shortly thereafter a single 

 specimen was received from Simons, collected at Minca, in tbe Santa 

 Marta region of Colombia, which was identified by von Berlepsch as 

 belonging to the same form. Mr. Brown secured only one specimen in 

 this region, and Mr. Smith's collectors only eight. Recently the Car- 

 negie Museum has received a series of no less than nineteen examples 

 from various localities in Venezuela, which, compared with the Santa 

 Marta series, show that the latter may be recognized by having little 

 or no Mars yellow on the crown, which is always so conspicuous a
