ON MAMMALS FKOM SI AM. [Feb. 5, 



Hah. Eahoug, Siam ; alt. 120 m. Several specimens also 



Tyi^e. B.M. 0.10.7.18. $ . 7th February, 1900. Collected and 

 presented by Mr. T. H. Lyle. 



In summer the pelage is similar, only clearer and brighter ; the 

 central median dark stripe is black, and the ear-tufts much shorter 

 and thinner. The general greyish coloration and the paleness of 

 the outer light stripes are sutficient to distinguish this race from all 

 the others. 



Mr. Lyle procured two other specimens besides the type : — 



a. 5 . Eahong, Siam ; alt. 120 m. 7th February, 1900. 



h. $ . Nan, Siam ; alt. 200 m. 31st May, 1900.

a. 2 • Eahong, Siam ; alt. 120 ra. 7th February, 1900. 



On comparing this specimen with those mentioned in my former 

 paper on Mr. Lyle's collection, one is able to note two distinct 

 varieties among the series — some specimens (e. g., b, c, d of my 

 former paper) differing from the other individuals in the greater 

 intensity of their colouring. In these individuals the uppermost 

 pale stripe is clear and distinct and is succeeded by a black stripe ; 

 the lower light stripe is very clear and broad, while there are traces 

 of another black stripe below that. The colouring of the whole 

 animal, moreover, is very light and the underparts are pure white. 

 In other individuals, collected by Mr. W. Davison in Tenasserim 

 during January, the whole animal is duller and the dark patch 

 below the uppermost pale stripe is precisely of the same colour as 

 the rest of the back ; the second light sti'ipe and the succeeding 

 darker stripe are by no means so clearly defined, while the white of 

 the underparts is tinged with yellowish. 



The type of Sc. mouJioti Gray is intermediate between these two 

 forms, as is also another specimen from Siam collected by Mr. S. S. 

 Flower in March. Mr. Davison's specimens having been procured 

 in January and the brighter individuals in June, these latter in all 

 probability represent the summer pelage of the species ; and 

 ^>,. mouhoti must be regarded as an individual of Sc. berdmorei 

 assuming the brighter pelage.
