270 Mr. J. L. Bonhote on 
two rows of yellow spots below and some crimson scales on 
anal segment. Primaries dark brownish grey; a median 
angular black transverse line; a black spot on costa beyond 
the cell, followed by a curved pale yellow band from costa 
to outer margin above vein 3; the apex and a large space 
from inner angle to vein 5 darker; some indistinct terminal 
yellowish spots. Secondaries yellow or roseate, the margin 
narrowly black, but more widely so at apex. Underneath 
there are crimson spots at the base of costal margins and a 
reddish quadrate spot at end of cell on primaries. 
Female.—Darker, with only the yellow band distinct on 
primaries. Secondaries black, with a curved subterminal red 
band, not reaching the inner margin.

XXXV.—On Sciurus caniceps and allied Species. 
By J. L. Bonuore, B.A. 
THE squirrels called ‘‘ Sccurus caniceps”’ and its allies have 
been less confused with a mass of names than those of some 
of the other groups with which I have dealt; this is no 
doubt due to the fact that a well-marked change of pelage 
was known to take place and the nearly allied forms were 
supposed to be specimens in various stages of change; 
thanks, however, to a large series at the British Museum, 
as well as to a considerable number of specimens brought 
home from the Malay Peninsula by the “‘ Skeat Expedition ” 
and now in the Cambridge Museum, I have been enabled to 
arrive at certain conclusions, which will, I trust, cause the 
various forms of this group to be more easily understood. 
In the first place five species may be recognized, viz. :— 
(i.) Sc. caniceps (the only species having a distinct 
breeding-dress), ranging through Burma, Siam, 
and the north of the Malay Peninsula. 
(ii.) Se. concolor, a nearly allied species with no seasonal 
change, confined, so far as we are aware, to the 
Malay Peninsula, at the northern extremity of 
which it meets with Se. caniceps. 
(iil.) Sc. epomophorus, sp. n., which ranges down the 
west coast of the Malay Peninsula from Banka- 
sun to Malacca. 
(iv.) Se. pygerythrus, from Burma aud Tenasserim. 
(v.) Sc. grisetmanus, from Cochin China.
