 ish); lower parts brighter, more yellowish, not so uniformly dull 

 brownish or ochraceous, 



Descri'ption. — Type, adult male, No. 181543, U.S.N.M.; Pulo 

 Mata Siri, Laurot Islands, Java Sea, December 11, 1907; Dr. W. L. 

 Abbott. Upper parts brownish olive, becoming more rufescent on 

 rump, and shading into dark dresden brown on upper tail -coverts; 

 the feathers of pileum edged with paler, which imparts a somewhat 

 scaly effect; tail between mummy brown and brownish olive, paler on 

 tips and inner margins of feathers, and edged on outer webs with 

 brownish olive; wings fuscous, all the quills and superior coverts 

 margined with brownish olive or hght brownish olive; sides of head, 

 neck, and breast brownish olive; cheeks and sides of throat light 

 brownish ohve; chin and upper throat buff, between deep olive buff 

 and deep colonial buff; jugulum and upper breast duU isabeUa color, 

 somewhat mixed with cream buff; abdomen dull marguerite yellow; 

 lower breast the same, but washed with isabella color; sides, flanks, 

 and thighs, light brownish olive; crissum and lining of wing chamois, 

 a little mixed with fuscous; ''iris red." Total length (in flesh ^), 

 194 mm,; wing, 84; tail, 75.5; exposed culmen, 13.5; height of bill 

 at base, 6.0; tarsus, 20; middle toe without claw, 13.5. 



The single specimen of this new race that Doctor Abbott obtained 

 on Pulo Mata Siri is identical with a good series of the same species 

 from Borneo ; and the birds from both these islands together differ, as 

 above set forth, noticeably in color from examples taken on the Malay 

 Peninsula and its islands, though apparently not in size. From Pyc- 

 nonotus hrunneus zapolius Oberholser,^ of the Anamba Islands, Pycno- 

 notus hrunneus zaphaeus may readily be distinguished by its more 

 rufescent or brownish (less greenish) upper surface, and darker, more 

 brownish and ochraceous (less grayish and yellowish) lower parts. 



The geographic distribution of Pycnonotus hrunneus zaphaeus, so 

 far as known, is confined to Pulo Mata Siri aiid Borneo. Thus Pyc- 

 nonotus hrunneus hrunneus becomes restricted to the Malay Peninsula 

 and its islands and to southern Tenasserim. 



Family TIMALIIDAE. 



MALACOCINCLA ABBOTTI SIRENSIS, new subspecies. 



Suhspec'tjic characters. — Similar to Malacocincla ahhottl olivacea 

 (Strickland), from the southern part of the Malay Peninsula, but 

 upper surface decidedly darker; lower parts duller, the sides of neck, 

 sides of breast, and sides of body less ochraceous (more grayish) ; and 

 jugulmn pale vinaceous buff instead of ochraceous buff.
