obscurely and coarsely banded dark and light. There is also a tendency 

 to a sliofht darkenino- along: the median line of the nnder-surface which 

 is, though very indistinctly, margined from the colour of the sides. 



In size this race most nearly approximates among mainland 

 animals to Sciarus Jlotreri, Bonhote (Ann and Maij. Nat. Hist., ser. 7, 

 vol. VII. p. 455, 1901), but, as Mr. Bonhote himself has noted, the 

 affinities of that species are not very clear so that for the present I 

 prefer to treat the Koh Phai animal as a race of S. Jlnlaijsoni. In colour 

 there is a partial resemblance to certain phases of S. hocoarti, Milne 

 Edwards (Wroughton, loc. cit. supra), but the presence of a white tail 

 in several examples indicates a connection with the Koh >Si Chang 

 squirrel. 



I have named this island race after Mr. C. B. Follett, tSuperinten- 

 dent of Police in charge of Koh Si Chang and Koh Phai, whose assistance 

 rendered it possible for me to send collectors to the latter island from 

 Koh Si Chano- after I returned to Bangkok.
