SCIUROPTERUS PLATYURÜS. 145 



NOTE XXI. 

 ON A NEW FLYING SQUIRREL FROM DELI, SUMATRA. 



BY 



Dr. P. A. JENTINK. 



March 1890. 



(Plate 7, figs. 3—10). 



Sciuropterus setosus, collected by Horner in the neigh- 

 borhood of Padang (Sumatra) and described by Temminck 

 in the » Fauna japonica", seems to be such an extremely 

 rare animal , that the type-specimen — an adult female — 

 is the only individual hitherto observed by collectors and 

 naturalists. Mr. Anderson is one of the few authors which 

 have paid some interest to our little animal , but he has 

 been not very successful in his remarks and observations. 

 For, having studied in our Museum all our specimens 

 before publishing his bulky work ^), he came to the remar- 

 kable conclusion that Temminck's setosus is a not fully 

 grown specimen of Sciuropterus (Pteromys apud Anderson) 

 pearsonii Gray. 



Trouessart (Catalogue des Rongeurs, 1881) blindly ac- 

 cepted Anderson's view, but incorrectly gave the locality, 

 as we find in Trouessart's Catalogue »Birmanie super., 

 Sikkim , Darjiling", instead of » Sumatra". Transiently I 

 observe that Temminck's » Fauna japonica" has been pu- 

 blished in 1850, 7iot in 1847, as Anderson and Trouessart 

 quoted. 



It seems that Oldfield Thomas , as in so many other 

 points , differs with Anderson concerning the specific identity
