SUMMARY OF THE INDIAN MAMMAL SURVEY. 



373 



Many years ago I pointed out 

 No. 253. palmarum, L, that the najne palmarum was origin- 



No. 254, tristriatus,Wsktevh.. ally given to the Madras squirrel, and 

 No. 255. layardi, Bl. had wrongly been confused with 



No. 256. sublineatus, Wa- the northern form with five white 

 terh. stripes (J. B. N. H. S. xvi, p. 406, 



1905), for which latter I proposed 

 the name jpennanti, with a subspecies argentescens, for the extreme 

 northern form, and more recently (J, B. N. H. S., xxiv, p. 430, 

 1916), the subspecific name lutescens, for the Kathiawar squirrel. 

 In my original paper (1. c.) I suggested comorinus as a subspecific 

 name for the Malabar form of palmarum, and more recently Thomas 

 and myself proposed the subspecific names favonicus, olympius, 

 brodiei and Jcelaarti for Ceylon forms oi' palmarum (J. B. N. H. S., 

 xxiv, p. 39, et seq. 1915), and kathleence for the Ceylon form of 

 sublineatus, Waterhouse. Finally, quite recently I established two 

 new species bengalensis, and robertsoni, and two subspecies, viz., 

 bellaricus of palmarum, and numarius of tristriatus for forms which 

 the Survey Collections showed recjuired names.* All these may be 

 arranged in key as follows : —

 ged with fulvous or rufous.

•Quite recently Robinson has described a peninsular form of the Ceylon layardi 

 under the name dravidianus.
