neio Asiatic Mammals. 639 



In working out a collection of Mammals from the Malay 

 Archipelago, brought together by Dr. J. Elbert, the following 

 two species have been found to need description : — 



Sciurus elhertce, sp. n. 



A pale-coloured member of the Sciurus leucomus-gronp. 



General effect of ujiperside between " olive " and '' raw 

 umber ^' (Ridgway), with a creamy-bufF tinge on head; hairs 

 with narrow blackish and broader pale rings of a shade 

 nearly approaching " Naples yellow " No. 2 or 3 (' Reper- 

 toire des Couleurs '). Underside " ochraceous buff" (Ridgw.), 

 in a second specimen between " ochraceous buff ^' and " ociira- 

 ceous." Hands, feet^ and sides of muzzle "cream-buff." 

 Tail more brownish than back, diffusely blackish at tip. 

 Tips of long tail-hairs " creamy white " ' Repertoire des 

 Couleurs '). Underfur '' olive-grey ^' (Ridgw.). 



Skull. Rostrum short and nearly parallel-sided ; nasals 

 narrow behind, suddenly broadening anteriorly, and strongly 

 convex transversely. Compared with a skull of S. rnowew- 

 ensis, Roux, from Bau-Bau, Buton, the palate is much 

 narrower, the teeth smaller but similar in sti-ucture. Opening 

 of posterior nares broader and with a distinct median spine 

 which is eihsent in moiceioe7isis. Bullae smaller and narrower. 



Measurements of skull (type) : — 



Palatilar length 14*5 mm. ; palate, breadth outside m^ 9*6 ; 

 least width of rostrum 7 ; nasals 10"6xG"6; breadth across 

 postorbital processes 20'9; mandible (alveolar point to con- 

 dyle) 23; length of upper tooth-row 7'9, of lower tooth- 

 row 8. 



Ti/pe. Senckenberg Museum, Frankfurt-a.-M. : no. 721. 

 Original number 227. Collected by Dr. J. Elbert. 



Ti/pe locality. Eempuhu, East Kabaena. 



Two specimens examined. 



Apart from its small size, this handsome squirrel is at once 

 distinguished by its pale colour. It gives me great pleasure 

 to associate wuth it the name of Mrs. Elbjrt, who accompanied 

 her husband during his expedition. 



Acanthion siitnbawce, sp. n. 



Smaller than A. javanicun and with a very different 

 skull. 



Externally very much like A. javanicu?n, somewhat paler 

 on neck and anterior portion of back, the brown with a slight 

 purplish hue. Spines of posterior back with more black, 

 usually with black or very short white tips. 



Skull. Squamosal region of brain-case narrower when
