obscurely and coarsely banded dark and light. There is also a tendency 
to a slight darkening along the median line of the under-surface which 
is, though very indistinctly, margined from the colour of the sides. 
In size this race most nearly approximates among mainland 
animals to Sciwrus jloweri, Bonhote (Ann and Mag. 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. finlaysoni. In colour 
there is a partial resemblance to certain phases of S. bocourti, 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, Superinten- 
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 Chang after I returned to Bangkok.
