Chars, subsj). — Similar to Hypothymis azurea calocara,"' but much 

 larger; blue of upper and lower parts paler and appreciably less 

 purplish; pileum strikingly paler, and much more contrasted with 

 back.

 Nicobar Island, Nicobar Islands, January 25, 1901 ; Dr. W. L. Abbott. 

 Upper surface, chin, throat, upper breast, with sides of head and 

 neck cyanine blue, much lighter on pileum; a somewhat crescentic 

 bar across jugulum, a narrow frontal line around the base of the 

 culmen, and a crescentic occipital patch black; wings and tail sepia, 

 more or less tinged or margined externally with marine blue, the 

 entire exposed surface of wing-coverts cyanine blue; posterior lower 

 parts white, anteriorly and laterally much tinged with blue, the 

 crissum somewhat so; under wmg-coverts exteriorly blue, interiorly

 with bluish; ''iris blackish brown; bill blue, the tip blackish; feet 

 dull blue." 



Measurements. — Two males: Wing, 73-73.5 (average, 73.3); tail, 

 71-74.5 (average, 72.8); exposed culmen, 12-13 (average, 12.5); 

 tarsus, 17-17.5 (average, 17.3). One female: Wing, 71; tail, 71; 

 exposed culmen, 12.5.; tarsus, 17 mm. 



Type-locality. — Gar Nicobar Island, Nicobar Islands. 



Geographical distribution. — Car Nicobar Island, Nicobar Islands. 



This form is geographically very near H. a. calocara, but it is so 

 much larger and so different in color that I can not consistently con- 

 sider it identical; it is larger than either azurea or prophata. So far 

 as known it is confined to the island of Car Nicobar.

HYPOTHYMIS AZUREA PONERA, new subspecies. 



Chars, subsp. — Similar to Hypothymis azurea prophata, but wing 

 averaging slightly, the tail considerably, longer; blue of upper and 

 lower parts in the male less purplish, and paler, except on pileum, 

 the upper surface thus noticeably more nearly uniform.
