two rows of yellow spots below and somo cr'nnson 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 3 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. BoNHOTE, B.A. 



The squirrels called ^' Sciurus 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.) So. caniceps (the only species having a distinct 

 breeding-dress), ranging through Burma, Siam, 

 and the north of the Malay Peninsula. 



(ii.) Sc. concolor, a nearly allied species with no seasonal 

 change, confined, so far as we are aware, to the 

 ]\Ialay Peninsula, at the northern extremity of 

 which it meets with Sc. caniceps. 

 (iii.) Sc. epomophorus, sp. n., which ranges down the 

 west coast of the Malay Peninsula from Banka- 

 sun to Malacca, 

 (iv.) Sc. pygerythrus, from Burma and Tenasserim. 



(v.) Sc. fjriseimanus, from Cochin Cliiiia.
