spot being confluent behind witli a black band on the crown in blakci, 

 while in nycaniis this black is almost wholly concealed by the brownish 

 white feather-tips. The crimson nuchal crescent is not so broad in 

 the females of blakei, while in both sexes of the latter the abdominal 

 red averages less in extent. There is practially no difference in size, 

 nor yet in general color, the differences of such a nature as were indi- 

 cated in the original description not holding good in the present series. 

 However, the type of nyeaniis, which I have consulted in this con- 

 nection, is not only much whiter about the head, but also has a larger 

 black postocular spot than any of the specimens now before me; and 

 is misleading to that extent, the real differentiating characters being 

 those I have specified.

In conformity with the previous discussion, this form should stand 

 as above. The present series is quite constant, as is also the type 

 series, which has been studied in this connection. 



The Cuban Centurus superciliaris, besides being much larger than 

 any of the Bahaman forms, averages much whiter on the wings, sides
