Show 56 ON M A M M A L S FROM SIAM. [Feb. 5, Hab. Rahong, Siam ; alt. 120 m. Several specimens also from Nan. Type. 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 sufficient to distinguish this race from all the others. Mr. Lyle procured two other specimens besides the type:- a. 2 < Rahong, Siam ; alt. 120 m. 7th February, 1900. b. 2 • Nan, Siam ; alt. 200 m. 31st May, 1900. 9. FUNAMBULUS BERDMOREI (Blyth). Sciurus berdmorei, Blyth, J. A. S. B. xvii. 1849, p. 603 ; id. loc. cit. xliv. 1875, extra no. p. 37 ; Thos. P.Z. S. 1886, p. 71. Sciurus mouhoti, Gray, P. Z. S. 1861, p. 137. Funambulus berdmorei (Blyth), Bonhote, P. Z. S. 1900, p. 194; Flower, P. Z. S. 1900, p. 359. a. 2 • Rahong, Siam ; alt. 120 m. 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 stripe 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. mouhoti 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 Sc. mouhoti must be regarded as an individual of Sc. berdmorei assuming the brighter pelage. 10.
