12. Petaurista magnificus (Hodgs.). 

 Pteromys magnificus, Blanford, op. cit., p. 364. 



A skin without skull collected by Major E. H. Sweet and Capt. 

 B. R. Nicholl near Renging has the upper surface glistening dark 

 maroon, intermixed with longer black hairs, parachute rich orange 

 rufous, underparts orange buff; tail clay brown, terminal three 

 inches black intermixed with brown and rufous, extreme tip pure 

 white. 



The specimen can be provisionally referred to this species but 

 the whole of the Indian and Indo-Chinese section of the genus is 

 in a state of great confusion. 



13. Sciuropterus alboniger, Hodgs. 



Blanford, op. cit., p. 367. 



A fragmentary specimen collected by Dr. Falkiner at Misshing 

 in February, 1912, is evidently this species. Another was seen at 

 Renging. 



14. Ratufa gigantea (McClell.). 



Sciurus giganteus, McClelland, P. Z. S., 1839, P- ^5° (Assam). 

 Sciurus bicolor, Blanford, op. cit., p. 373. 



Ratufa gigantea, Wroughton, Journ. Nat. Hist. Soc. Bombay, 

 xix, p. 889 (1910). 



There is a specimen of the large black and buff squirrel 

 from Upper Renging, 2,150 ft., collected by Capt. M. de Courcy 

 and another flat skin from Pasighat, secured by Major E. H. 

 Sweet and Capt. B. R. Nicholl which differ in no particulars. 

 Externally they are typical examples of this race which extends 

 through North Burma and Siam grading into the Malayan species 

 R. melanopepla in northern Tenasserim. The measurements of 

 the skull are slightly smaller than those given by Wroughton for 

 R. gigantea and approach those of R. macruroides (Hodgs.), but 

 the colour characters are those of the former race. 



15. Sciurus erythraeus erythrogaster, Blyth. 



Sciurus erythrogaster , Blyth, Journ. Asiat. Soc. Bengal, xi, 



p. 970 (1842). 

 Sciurus erythraeus erythrogaster , Bonhote, Ann. Mag. Nat. 



Hist., (7) vii, p. 162 (1901). 



The whole series of red-bellied grizzled squirrels comprised 

 under the two group names Sc. erythraeus, Pall., and Sc. castaneo- 

 ventris, Gray, are involved in almost inextricable confusion, 

 partly owing to the insufficiency of the original descriptions and 

 the bad condition or non-existence of the types, and partly to the 

 paucity of exactly localized and properly collected material and 

 the doubt as to whether certain of the forms undergo seasonal
