striped-squirrel * pair of which he says frequented his house at 

 Tellicherry : 



" Very similar to the last, but generally darker, the face, fore- 

 head, back and haunches, more or less tinged with rusty-red, or 

 reddish brown ; the stripes small, narrower than in the common 

 one, and not extending the whole length of the back ; tail beneath, 

 distinctly rusty ; sides darker than in palmarum. 



Length, head and body, 7J inches ; tail 7J. 



Mr. Blyth says he observed no difference in size. I have always 

 found this species slightly larger and conspicuously heavier than 

 palmarum : 



" This species is so exceedingly similar to the last that many 

 would only look on it as a slight variety, but it differs very remark- 

 ably in its voice, which is much less shrill, and indeed quite 

 different in character. 



With reference to the very great similarity of these two squirrels, 

 Mr. Blyth well remarks, " the slight differences of form and color 

 between these two species so distinct in their voice and habits, 

 should indicate the extreme caution necessary ere we conclude 

 other allied races to be merely varieties of the same from their 

 general similarity of size and coloring." 



Jerdon also mentions two other races of striped squirrels, which 

 may perhaps sometimes be confounded with the common one ; the 

 first, " Sciurus Layardi, the Travancore striped squirrel" he thus 

 describes : 



" Much darker than the last, being of a dark dingy olive color 

 with a tinge of ashy ; middle of back, black with a short yellowish 

 streak in the middle and a faint and shorter streak on each side ; 

 tail tipped black, rusty in the middle ; lower parts somewhat 

 ferruginous. 



Size of the last or a trifle larger. 



This well-marked race is found in the mountains of Travancore 

 and in Ceylon." 



And the second, 



Sciurvs sublineatus, the Neilgherry striped squirrel, " which 

 he procured in the dense woods on the Neilgherries, where how-
