The small size, much more bluish posterior lower parts, and darker, 

 more uniform upper surface of this form distinguish it from Hypo- 

 thymis a. coeruleocepJiala, as do its much more bluish sides, flanks, 

 abdomen, and crissum, less contrasted pileum, and usually less pur- 

 plish upper parts from H. a. azurea. It is very similar to Hypothymis 

 a. amelis, from Nias Island, but the male is lighter, somewhat less pur- 

 plish blue both above and below; the abdomen is more whitish and 

 less extensively washed with blue; the crissum less heavily bluish; 

 the axillars more whitish and less tinged with blue. 



Females are less whitish on the abdomen than those of H. a. azurea, 

 but are not otherwise different. Specimens from the following islands 

 have been examined: Nankauri, Great Nicobar, Kamorta, Trinkut, 

 and Tilanchong.
