This species is closely related in form to Platycichla brevipes, 

 Baird, although tlio lower mandible is rather deeper and stouter, 

 the upper less attenuated viewed from above. The first quill is 

 longer, two-fifths the second instead of one-third, and not qu'te as 

 mneii pointed ; the tail is more graduated and emarginattJ ; the 

 feet much the same. The principal difference, therefore, is in the 

 stouter lower mandible, and less attenuated bill, longer first pri- 

 mary, aud more emarginate and graduated tail. 



From Myiadedes armillatus it differs in stiffer tail and falcate 

 acuminate outer primary. With such species, however, as M. 

 obscurus and venezvvlensis, it has very close relationships in form, 

 80 much indeed that it is very difficult to separate them generically ; 

 the tail feathers are perhaps broader and stiifer, and the bill rather 

 longT and stronger; the wings and feet are precisely similar. 



The two citations from Lesson, quoted in the synonymy, by Dr. 

 Sclater, hardly appear to belong to this species, but rather to un 

 allied one. The description in " VEcho" 1 have not seen, that in 

 "Desc. des Mam. et Ois." shows many discrepancies. 



For the opportunity of examining this species I am indebted to 

 Dr. Sclater. I have seen a second specimen in the museum of the 

 Phila'lelphia Academy.
