BIRDS OF THE ANAMBA ISLANDS. 



33 



This new race may be distinguished from Celebes specimens of 

 Hypurolepis javanica frontalis (Quoy and Gaimard) 1 by reason of 

 larger size; duller, darker throat; darker, somewhat less brownish 

 sides and flanks ; less dull, less brownish, and therefore more strongly 

 contrasted whitish middle portion of abdomen. From Hypurolepis 

 javanica domicola (Jerdon), 2 which is a recognizable race from south- 

 ern India and the Malay Peninsula, Hypurolepis javanica abbotti 

 differs in duller, darker throat; darker, more grayish (less rufescent) 

 brown of sides and flanks; less brownish tinge of the whitish middle 

 portion of the abdomen, whereby this latter is more sharply in con- 

 trast to the lateral brown areas; and in the more conspicuously 

 spotted appearance of the posterior lower surface. 



One specimen (No. 171060, U.S.N.M.), taken on Pulo Telaga, 

 September 14, 1899, is a juvenal male, and differs from the adult 

 in entirely lacking the bay frontlet ; in having the upper parts very 

 much duller, the wings with scarcely any metallic sheen; and lower 

 surface very much lighter throughout, the crissum dull brown, 

 without any black. One of the other birds (No. 171090, U.S.N.M.) 

 has the outer primaries in process of molt; and most of the remaining 

 examples show indication of molt in the body plumage. 



Doctor Abbott reported this species common on Pulo Jimaja, 

 September 17-28, 1899: and observed it on Pulo Siantan, August 19 

 to September 13, 1899. He obtained seven specimens on the various 

 islands of the Anamba group. 



The subjoined table of measurements includes all our Anamba 

 examples of Hypurolepis javanica abbotti, and for comparison some 

 specimens of Hypurolepis javanica javanica from Java.
