124900) certainly has this ridge fully as much developed as in a 

 specimen of C. e. eximia (Bangs coll. 1448), although in general 

 the ridge is more distinct in C. e. eximia. Some specimens of B. c. 

 cucullata also exhibit this character strongly. The two forms, 

 C. e. eximia and C. e. ckloronota, very probably intergrade, and are 

 considered geographical races by Chapman (Bull. Am. Mus. Nat. 

 Hist., xxx vi, 1917, p. 603). 



Bangsia gen. now 



Type. — Buthraupis arccei cceruleigularis Cherrie. 



Characters. — In general resembling Buthraupis, but differing consider- 

 ably in shape of bill and form of wing. Bill rather long and comparatively 

 slender; depth at base about equal to width and to gonys (in this respect 

 resembling Buthraupis), but decidedly less than length of maxilla from 

 nostril. Wing long, about four times the length of the tarsus; more 

 pointed than in Buthraupis, third primary (from outside) longest, the first 

 very little shorter than the third and longer than the fifth (or sixth?); 

 primaries exceeding secondaries by about the length of the tarsus. Tail 

 comparatively much shorter than in Buthraupis, about one half or a little 

 more than one half the length of the wing; slightly rounded or nearly 

 square (slightly forked in B. a. cceruleigularis), not so decidedly rounded 

 as in Buthraupis. 



The following species and subspecies should be referred to this 

 genus : 



Bangsia arccei arccei (Sclater and Salvin). 

 Bangsia arccei cceruleigularis (Cherrie). 

 Bangsia mclanochlamys (Hellmayr). 

 Bangsia rothschildi (Berlepsch). 

 Bangsia edwardsi (Elliot). 

 Bangsia aureocincta (Hellmayr). 



Remarks. — It gives me great pleasure to dedicate this well- 

 marked genus to Mr. Outram Bangs. 



I have seen only one specimen each of B. mclanochlamys, B. 

 rothschildi, and B. edwardsi, and two of B. aureocincta. In all 

 these the bill seems to be a little heavier than in B. a. arccei and B. a. 

 cceruleigularis, especially the latter, and the fifth primary is longer
