other forms," evidently applies as well to the large series from French 

 Guiana examined in this connection. This series represents a form which 

 is obviously specifically distinct from the form with buffy wing-bands, with 

 which it occurs associated, and the name macconnelli of Chubb, being the 

 first applied to the plain-winged bird, will thus become the specific appella- 

 tion of the group. Our series is very uniform, although specimens taken in 

 the fall months are perhaps a trifle darker than those shot in May and June. 

 From one to three outer primaries are narrowed terminally in a majority 

 of the specimens. There is no difficulty whatever in distinguishing the 

 series as a whole, or any individual example, from the form of P. oleaginea 

 inhabiting the same region. 



Specimens examined. — French Guiana: Tamanoir, 24; Mana, 1; Pied

IV, 1919, 303 (Mount Roraima [type-locality] and Merum6 Mountains, 



British Guiana; orig. descr.; type in coll. Brit. Mus.). 



Subspecific characters. — Similar to Pipromorpha macconnelli macconnelli, 

 but more richly colored throughout, the wings and tail edged with dull 

 orange citrine, and the upper tail-coverts, throat, and upper breast strongly 

 shaded with this same color, passing into bright yellow ocher on the posterior 

 under parts, axiUars, and under wing-coverts. 



Measurements. — Male (four specimens): wing, 61-64 (63); tail, 43-48 

 (45); bill, 11-12 (11.6); tarsus, 15-17 (16). 



Range. — Known only from Mount Roraima and the Merum6 Mountains, 

 British Guiana. 



Remarks. — Judging from the available material, the present form is a 

 strongly characterized one, being decidedly more richly colored than true 

 macconnelli, the under parts especially, which are fully as deep as in P. 

 rufiventris. So far as known, it is confined to the highlands of British 

 Guiana, from 3500 feet upwards, the type coming from Mount Roraima. 

 While there are specimens extant of both this form and P. oleaginea 

 chloronota collected by Whitely from the Merum6 Mountains, Mr. Chubb's 

 description was certainly based on a bird of the plain-winged type. 



Specimens examined. — British Guiana: Mount Roraima, 3; Merum6
