XXI. A NOMINAL LIST OF THE SCIURIDAE OF 



THE ORIENTAL REGION WITH A LIST OF 



SPECIMENS IN THE COLLECTION OF THE 



ZOOLOGICAL SURVEY OF INDIA. 



By Herbert C. Robinson, C.M.Z.S., 



and

We owe to the kindness of Dr. N. Annandale the opportunity of 

 examining the whole collection of Oriental Sciuridae in the possession 

 of the Zoological Survey of India, a collection which is of great interest 

 to Mammalooists as containino- the material on which the work of 

 Blyth and Anderson was based. In the course of our work we have 

 reviewed the whole recent literature of the group which, owing largely 

 to the exertions of the veteran American Field Naturalist Dr. W. L. 

 Abbott and the collectors of the Bombay Natural History Society's 

 Mammal Survey, is now very extensive. We have, therefore, attempted 

 to give a list of all known forms from the Oriental Region proper, ex- 

 cluding Celebes and the Philippines, with the species of which we are 

 not familiar, though those interested in the latter country will find an 

 exhaustive list by Hollister ^ in the " Proceedings of the United 

 States National Museum," vol. 46, pp. 299-341 (1913). Certain Chinese 

 and Japanese species are included, but the list does not pretend 

 to comprise all the forms from these areas, which are mainly Palaearctic. 



The nomenclature used is as far as possible trinomial as best in- 

 dicating natural relationships, but in many groups this has not been 

 adopted, owing to paucity of material. 



Family SCIURIDAE. 

 Subfamily PETAURISTINAE. 



Genus PETAURISTA, Pallas, 1792. 



In cataloguing the specimens of this genus in the Indian Museum 

 we have in the main followed Mr. R. C. Wroughton in his paper on 

 " Oriental Flying Squirrels of the Pteromys group " ^ and like him have 

 been compelled for the greater number of the forms to use a binomial 

 nomenclature, though there is not the slightest doubt that the rela- 

 tionships of by far the larger proportion are merely subspecific and that, 

 when a sufficient number of properly authenticated specimens are 

 available, we shall be able to sort them" out from the present unwieldy
