This species has been recorded by Doctor Hartert ^' from Bunguran 

 Island. 



Family HEMIPROCNIDAE 



HEMIPROCNE LONGIPENNIS ANOCHRA, new subspecies 



Subspecijic characters. — Similar to Hemiprocne longipennis harterti^ 

 from Sumatra, but with rump and upper tail coverts of a darker and 

 duller gray; anterior lower parts darker, duller, and not so bluish 

 (more brownish). 



Description. — Adult female, U.S. N.M. No. 174684, Bunguran Island, 

 Natuna Islands, July 3, 1900; Dr. W. L. Abbott. Upper parts 

 metallic Lincoln green, with irregular spots of bronzy, of metallic 

 dusky dull bluish green, metallic dark delft blue, and of metallic 

 dusky slate-black; rump and upper tail coverts dull storm gray; tail 

 chaetura black, on broad terminal portion with a sheen like the green 

 of the back, but much duller, outer webs and subtenninal part more 

 or less bluish, but much duller than on the upper parts; wings chaetura 

 black, the inner webs of the quills fuscous, the outer primaries with a 

 purplish sheen, the inner primaries metallic dark ivy green, the 

 secondaries •wdth their outer webs bluish like the upper parts, but 

 duller, longest tertial slightly metallic dull andover green on outer 

 web, between light drab and light grayish olive on inner web, inner 

 tertials between pale mouse gray and olive-gray; lores velvety black; 

 sides of head, of neck, and of breast similar in color to the upper 

 parts, but the auric ulars and subocular region duller and more 

 brownish; chin mouse gray; throat, breast, and jugulum, between 

 mouse gray and dark olive-gray ; sides and flanks between light mouse 

 gray and deep olive-gray, shading into white medially; lower tail 

 coverts rather light neutral gray; shading laterally through pallid 

 neutral gray to almost white medially; crissum and flank tufts white; 

 lining of wing somewhat metallic dull dark ivy green, the edges of the 

 wing darker, verging toward chaetura black but still with some 

 greenish sheen. 



In addition to the Natuna Islands, this new race inhabits the 

 Anamba Islands, the Malay Peninsula, Tenasserim, and Burma. 

 This division of Hemiprocne longipennis harterti restricts the geo- 

 graphical distribution of the latter to chiefly the islands of Sumatra, 

 Banka, Billiton, and Borneo. Birds from the Malay Peninsula are 

 intermediate, but are nearer the Natuna Islands form. Those from 

 the Anamba Islands appear to be just the same as Natuna birds.
