These further examples show that the specimen formerlj'' at- 

 tributed to Patani was so done correctly. Thej' only differ from it in 

 having less, or no white on tlie hands and feet and in the greater de- 

 finition of the black stripes below the white of the sides. All three 

 are very typical in appearance. This form occupies Johore, Malacca 

 and Pahang east of a line joining Malacca and the bend of the Pahang 

 River, and probably all the east coast of the Peninsula north to Patani 

 or further. 



The other form occurring in Peninsular Siam, S.p. irraiji Kloss, 

 differs in having the shouldei's washed with rufous ; it inhabits the 

 rest of the Peninsula from Trang southwards to Kuala Lipis, Pahang 

 (typical locality), except the small area from Central Perak to Selangor 

 inland to, at least, the summit of the main range which is occupied by 

 a form with deep rufous shoulders, S. p. humei Bonhote.

This race differs from S, <:. milleri (antea. p. 20) in being 

 smaller and rather darker in colour, and is without the j'ellow areas on 

 the sides of the neck, flanks and inguinal region : the tail is only 

 slightly blackened at the tip which is not clearly margined as in 

 milleri.
