Streseman has dealt with these Cuckoos at some length in 
Novitates Zoologicae, vol. xx, p. 321, but his geographical ranges are 
very unsatisfactory. Manipur and Cachar, according to him, are 
occupied by different races. Mr. Herbert's specimens have the wings 
varying between 191 and 210 mm. (juv. ¢ 191 mm.) and the bills 
very large, ranging from 26 to 29 mm. if measured from the edge of 
the nostril, and up to 39 mm. if measured from the forehead to the 
tip. They have, of course, the interscapulars red, not black.

The wings of the males run from 149 to 164 mm. and of the 
females from 143 to 156. The smallest adult male is 155 mm, 
These birds are rather small when compared with North 
Indian and Burmese specimens, but are otherwise exactly similar, * 
The females and young males have the bills wholly black as in true 
fasciata,
