BIRDS FROM SIAM AND THE MALAY PENINSULA 355 



sides of the cbest have 9 few dusky mottlings and the flanks and under 

 tail coverts have a brownish wash; otherwise white. A single speci- 

 men from Borneo appears to be a little darker above than the Trang 

 series. 



The five adults from Trang measure: Wing, 61.5-66 (63.7); culmen, 

 13.5-14.5 (13.8) mm. A single male from Borneo: Wing, 68; culmen, 

 14 mm. 



The sexes are alike and apparently do not differ in size, judged 

 from a single female. 



The species ranges from Borneo to the Malay States and northward 

 in Peninsular Siam to Trang. 



ANUROPSIS MALACCENSIS MALACCENSIS (Hartlaub) 



Brachypteryx malaccensis Hartlaub, Rev. Zool., 1844, p. 402 (Malacca). 

 Anuropsis malaccensis driophila Oberholser, Smithsonian Misc. Coll., vol. 74, 

 no. 2, p. 9, 1922 (Kao Soi Dao, Trang). 



One male and two females, Sichol, Bandon, August 28, 19, 1929, 

 May 27, 1930. 



Dr. W. L. Abbott collected one male and one female at Kao Soi Dao, 

 1,000 feet, Trang, February 2, 19, 1899; two males, Singapore Island, 

 May 12, 14, 1899; one male and one female, the Dindings, Straits 

 of Malacca, April 13, 15, 1900; one male and one female, Rumpin 

 River, Pahang, May 27, and June 2, 1902. He gives the soft parts as: 

 Iris dark or dull red; upper mandible black or horn brown, lower 

 mandible leaden; feet pale fleshy brown or pinkish fleshy. 



Apparently there is little or no difference between the sexes in size 

 or color; 



The specimens from Trang and Bandon average a trifle paler above 

 than the series from the Malay States, but the difference is very slight 

 and might disappear in a larger series. In fact, individual specimens 

 that are almost exactly alike can be picked out of either series. In 

 my opinion, the differences are too slight to recognize by name. There 

 is little or no difference in size. 



Seven specimens from the Malay States (four males and three 

 females) measure: Wing, 62-72 (67); culmen, 15-17 (16.2); tarsus, 

 27-30 (28.2); middle toe and claw, 19-21 (20) mm. Five specimens 

 from Trang and Bandon, two males and three females: Wing, 61-70 

 (65.2); culmen, 15-16.5 (15.7); tarsus, 26-30 (27.7); middle toe and 

 claw, 19-21 (20) mm. 



This form ranges from the Malay States northw^ard in Peninsular 

 Siam to Bandon. Robinson and Kloss ^' have recorded it from 

 Trang; Baker ^* from Tung Song; de Schauensee " from Nakon 

 Sritamarat.
