to specimens from Trinidad which, although not typical oi.niger are far 

 nearer to that form than to the form from Santa Marta. If, as Hellmayr 

 suggests (Archiv. fiir Naturg., 1912, p. 90), Sclater's type did not come 

 from Santa Marta then the bird from Santa Marta requires a new name. 

 Ridgway (Bull. U. S. N. M., 50, IV, 831) has already clearly stated this 

 case, but I cannot agree with him that two adult males in the American 

 Museum collection from San Antonio and Cumanacoa, Venezuela, respec- 

 tively, are nearer to niger than to dnereveentris. In the color of the under- 

 parts they are fairly intermediate, but in the grayness of the rump and upper 

 tail-coverts they are obviously nearer cinereiventris. An adult male from 

 El Pilar, Venezuela, however, is exactly like specimens from Trinidad. 

 But whatever may be the status of the Venezuelan bird those inhabiting 

 Santa Marta and Trinidad represent two quite unlike races.

A female from La Morelia agrees essentially with a female from Cayenne.

Fourteen specimens (12 males, 2 females) from the Subtropical Zone 

 of the Eastern and Western Andes are to be referred to this form, the exact 

 status of which appears not to have been satisfactorily determined. The 

 gray nuchal collar supposed to be diagnostic of the species is well developed 

 in some specimens and wholly wanting in others from the same locality, 

 (San Antonio) and such birds differ from true cinereiventris only in their 

 larger size and paler underparts. It is quite probable that the two forms 

 intergrade.
