axillary region, but none of the series possess the rufous patches seen 
in some examples of S. f. folletti; as compared with that race the 
dark element is much increased and the colour effect is much less of a 
pale olive buff. 
Young animals resemble adults but have the grizzle of the 
upper parts much finer and the pale colour reduced in quantity. 
There appears to be no seasonal variation in these squirrels. 
The type series of follettt was taken in February, and I have lately 
been sent a set obtained in July by Mr. W. J. F. Williamson’s col- 
lector; there is no difference between two lots; in both the great 
majority are without rufous colouration and in both two or three 
individuals exhibit rather irregular patches of rufous ( principally 
inguinal and axillary ) on the underparts. 
Type Adult male (skin and skull) No 2266/C. B. K- 
Collected on Koh Lan, Inner Gulf of Siam on 29th October, 1916. 
( For measurements see table postec). 
Named after Mr. E. W. Trotter, Major-General of Gendar- 
merie, Siam, who was the first to collect specimens of this Koh Lan 
squirrel, 
29. Tamiops macclellandi liantis, subsp. nov. 
Type. Adult female (skin and skull) No. 2337/C. B. K. 
Collected at Satahip near Cape Liant, 8. E. Siam on 2nd November 
1916. 
Characters. A race nearest T. m. rodolphi (M- Edw.), from 
which it differs in having the outer pale stripes continued without 
interruption or diminution over the shoulders; in the Cochin-China 
animal these stripes instead of being continuous from muzzle to 
rump are either broken on the shoulders or very much reduced 
there. 
Colour, Forelimbs and sides greyish strongly suffused with 
buff, the hairs with grey bases and buffy tips. Four yellow stripes 
on the back ; the outer pair pale cream extending from the base of 
the tail to the muzzle passing below the ear and eye but above 
the vibrissae where they are duller in colour: the inner pair, com- 
mencing indistinctly at the shoulder and extending to the base of 
the tail, ochraceous-buff anteriorly, warm buff on the rump. On the
