.S. strigtda ccista»icaiid({, in v/hich tbe remarkable differeoce of the outer rectrices 

 has never been projierly described before. It differs, however, from both <S'. strigtda 

 strit/idn and .V. striqidd caxtanicaiKhi in its sombre cohmr, the nn<ler surface being 

 yellowish olive, only an ill-defined cential line remaining orange-yellow. The 

 nnder fail-coverts are dnil veMowish olive, instead of yellow. The white tips to the 

 secondaries are much narrower, being not more than \\ mm. wide. The crown is 

 dark olive-brown. Wing 68 — 69, tail 70 — 72, metatarsus 20, bill Hi ram. 



Ihih. Gunong Tahan, Pahang, Eastern Malay Peninsula, October I'jol, 

 between .")UI)U and 7000 ft. Si.x specimens, of both sexes, were procured by Mr. 

 John Waterstradt. This form occurs also on the Perak mountains. 



I thus recognise now the following forms of S. strigida : 



1. Siva strigida strigida Hodgs., Himalayas, (Nepal, Sikkim). 

 Siva strigula Hodgs., Ind. Reriew ls:5s. p. 80 (Nepal). 



2. Siva strigida castanicaitda Hume, Mountains of Tenasserim and Toungiigoo. 

 Siva castanicauda Hume, Strag Featli. v. 1877. p. 100 (" Moolyit, 



Tenasserim Hills'"). Dr. Sharpe {Cat. B. Brit. Mn.-i. vii. p. 030) and Mr. 

 Gates (Bird.f Brit. India i. 1889. p. 209) include in the distribution of this 

 form also Bhutan, but it seems to me that the Bhutan birds are inter- 

 mediate between S. strigida ittrigida and 5'. strigula castanicauda. 



3. Siva strigula malayana Hart., Malay Peninsula, high mountains (Gunong 



Tahan and Gunong Ijau). 



154. Mesia argentauris Hodgs. 



Mesia argentauris Hodgs., Ind. Revii-w 1838. p. 88 (Nepal). 



Not rare on Gunong Tahan, between 5000 and 7000 ft. 



Mr. A. L. Butler obtained these birds in March 1898, on Gunong Ijau. He 

 found the iris reddish brown, bill and legs light orange. 



The birds from Gunong Ijau and Tahan are like Himala3'an ones, but the 

 crimson wing-patch is generally larger, extending from 16 to 19 mm. beyond, 

 the wing-coverts. This patch, however, varies in extent in Indian birds, so that I 

 do not feel justified to separate the two forms. These Malayan birds have nothing 

 to do with Mesia laurinae (Salvad.) from Sumatra. 



155. Erpornis xantholeuca Hodgs. 



Erpornis .cantholeiwa Hodgs., Jo/^r/;. As. Soc. Beiig. xiii. (1844) p. 380 (Nej).il). 

 Gunong Tahan, 1500, 3000 and between 2000 and 5000 ft. 



156. Suya waterstradti sp. nov. 



Suxja supra olivacea. Remigibus brnnneis, colore tergi marginatis. Cauda 

 tergi colore. Su])ra oculis uonnullis plumis albis, nee snperciliaribus distinctis ? 

 Gutture, jtectore abdoiuinefpie albis, pectore nigrj strl.ato, pei'toris lateribns olivace s, 

 hypochondriis, tibiis, subcaudalibusqne fulvescentibus. Subalaribus pallide luteis.

"J." Gunong Tahan, Oct. 1901, 5000—7000 ped. Waterstradt coll. 



A specimen of a Suya from Gunong Tahan, shot between 500il and 70(10 feet, does 

 not agree with any of the known species. The ujiper surface is uniform dark olive, 

 outer aspect of wings and tail similar. Underside white, breast heavily streaked wii ii 

 black, sides of breast olivaceous, fl;inks, thighs, and under tail-coverts fulvescen",
