HYPOTHYMIS AZUREA OPISTHOCYANEA Oberholser. 



Hypothymis azurea opisthocyanea Oberholser, Proc. U. S. Nat. Mus., vol. 39, 

 February 25, 1911, p. 602 (Pulo Piling, Anamba Islands). 



Doctor Abbott obtained nine specimens — 5 males, 4 females — of 

 this recently described form from the Anamba Islands, collected 

 August 18 to September 11, 1899, on Pulo Piling, Pulo Riabu, Pulo 

 Manguan, and Pulo Siantan. Two of the three adult males from 

 Pulo Siantan are rather less bluish on the posterior lower surface, 

 particularly on the lower tail-coverts, than the other examples, but do 

 not differ in size. There is some individual difference among all the 

 males in the color of the upper parts, especially the pileum, this due 

 largely to wear, as the tone of the blue seems particularly liable to 

 change from this cause. One bird from Pulo Manguan, taken, Sep- 

 tember 1, one from Pulo Riabu, August 18, and two from Pulo 

 Siantan, August 24, are just completing the molt. Except for their 

 larger size the females of this race are very close to those of Hypothy- 

 mis azurea azurea, though the lower surface is usually more exten- 

 sively shaded with blue. An immature male from Pulo Manguan, 

 taken, August 31, is like the adult female, but has the secondary 

 wing-coverts much more deeply bluish. One of the females had the
