paler, less purplish blue, the head darker, slightly less purplish blue, 

 and not so much in contrast to the remaining upper surface; the 

 crissum pure white; and the axillars pure white, but slightly, if at all, 

 washed with blue exteriorly. The female is apparently indistin- 

 guishable from that of Hyjyothymis azurea prophata. In the white- 

 ness of its posterior ventral surface Hypothymis a. leucopTiila is like 

 Hypothijmis azurea azurea, but is easily distinguishable by its usually 

 longer wing, less purphsh blue color, lighter back, rather darker 

 pileum, with consequently less contrast between head and back. 



Birds from South Pagi Island are identical with those from North 

 Pagi ; and Hypothymis a. leucopliila apparently does not range beyond 

 this group of islands.
