 are glossy black with a dark brownish shade: the hind- 

 most part of the back is of a deep brown color. If the 

 given locality is correct , this specimen should be the most 

 southern representant of the species. — 47. Adult, Brazil, 

 Hamburgh Museum. Upperparts grizzled , brownish black , 

 hairs of tail black with light brown tips , lowerparts red- 

 dish brown ; head , sides of body , legs and feet colored like 

 back ; a light brown spot behind the ears. It is not with- 

 out hesitation that I bring this specimen under the head 

 variegatus ; but I do so because it is the only form known 

 to me with which it agrees in some degree.
