-This very distinct little squirrel is characterized by its 
unusually inconspicuous striping above and by the strong 
yellowish buffy of its lower surface—in fact, it is above one 
of the dullest and below one of the brightest of the genus. 
It does not appear to be nearly related to any. described 
species, 
Tamiops lylei, sp. n. 
Near T. barbet ; greyer on sides, more buffy on nape. 
Size about as in barbei. General appearance of light. 
lines rather uniform, the inner and outer subequal in intensity. 
Subocular and external light lateral lines continuous over 
shoulder, as in barbe?, differing in this respect from 7” ro- 
dolphei, in which the lines are interrupted. Median dark 
line, as in rodolphet, with a narrow thread of pale brownish 
along its centre, so that, as a dark line, it is not truly and 
literally “median” ; the present species and rodolphei are 
the only members of the genus in which this character is 
found. Crown and fore-back “ tawny-olive”’ or dark “ clay- 
colour,” a ready distinction from barbei and leucotis ; behind 
this colour darkens into the outer dark lines of back, but is 
not known to occur truly black. Inner light lines strong 
buffy, outer whitish buffy. Outside them an inconspicuous 
dark edging. Sides and hips pale olive-grey (“ light greyish 
olive’) which is continued down to the ankle. Under sur- 
face ochraceous buffy, richest on the chest, more grey-mixed 
on the belly. Proectote of ear black, with a well-developed 
white tuft at tip, the hairs of the latter white nearly or quite 
to their bases. Hands and feet grizzled buffy. ‘Vail slender, 
the tips of the hairs white. 
Skull as usual.
