SCIURUS ROSENBERGII. 37 



bes, however he does not state the exact part of that Island, 

 where it was collected. The first two species differ from our 

 animal by having a white lateral streak on each side of the 

 body; Sciurus leucomus by having a white patch behind the ears ; 

 Sciurus rubriventer by the red-coloured belly and larger size ; 

 Scimnis murinus by its naked ears , grey coloured belly and 

 smaller size; Sciurus ephippium^ which belongs to the lar- 

 gest species of Squirrels in existence, by its size. 



Our species being new to science, I propose to name it 

 in honour of its discoverer, 



Sciurus Rosenbergii, n. sp. 



General size and colour as in Sciurits Steerii ^) from Bala- 

 bac (Philippine-islands), but the latter is larger and has 

 the tail shorter than the body and head; finally there are 

 little differences in colouration. General tint of the upper- 

 parts of the body and outside of legs rusty brown; the 

 colour of the underparts is much brighter. In the second 

 specimen of Günther's Sciurus Steerii from Palawan , o. c. , 

 p. 736 , the lower parts are pure white. 



Hairs of the back with a broad black ring towards 

 the tip. 



Tail darker than the back, each long hair is embellis- 

 hed with a broad black ring and a very long black tip. 

 In the Sciurus Steerii from Balabac the hairs of the tail 

 are of moderate length and without black tips , o. c. , p. 736. 



In-and outside of the ears closely covered with hairs 

 which do not form a pencil. 



Whiskers black and not projecting beyond the tips of 

 the ears. 



Toes and fingers and also the fore and hind-feet closely 

 covered with hairs on the upper parts , the hairs being 

 here dusky near the base with silvery tips. 



Cutting-teeth bright orange.
