Mr. O. Thomas on Tmo new Bornenn Squirrels. 215 



N. Borneo (killed Dec. 24, 1891) ; of Mr. Fryer's specimens, 

 Sandakan. 



Specimens of this interesting form have, as already men- 

 tioned, been in the Museum since 1880 ; and ever since they 

 came I have been on the look out for more examples, to see 

 how far their characters were constant. Now that Mr. Eve- 

 rett's specimen, whicli is chosen as the type, proves to agree 

 with them in every respect, it is evident that the animal 

 ought to go no longer undescribed, as it is clearly a distinct 

 geographical race, differing in my opinion sufficiently to be 

 called a species. At the same time I admit that some zoolo- 

 gists would consider it to be only a subspecies ; but even in 

 that case it is one which clearly requires a name of its own. 



A specimen of aS'. hippurus in the Museum from Mount 

 Penrisen, Western Sarawak, is quite similar to Malaccan 

 examples, and others from the south of the island, preserved 

 in the Leyden Museum, are also of the usual red-bellied type. 

 Nor, again, does the type of S. hippurus^ var. horneensiSj 

 Gray ■^, show any approximation to IS. Pryeri. 



Sciurus Hoseiy sp. n. 



A striped squirrel of the size and somewhat the general 

 appearance of S. Berdmorei^ Bly., but the muzzle short, as in 

 the ordinary species. Ground-colour of body olivaceous 

 greenish grey, but this colour is only present in purity along 

 the sides of the body and on the face, the nape and shoulders 

 being suffused with fulvous, which narrows and brightens 

 posteriorly into a defined dorsal fulvous line, on each side of 

 which there are, firstly, a black, then a pale yellowish-white, 

 and then another black line. The resulting effect is not 

 unlike some of the darker-coloured specimens of 8. tristriatus, 

 Waterh. (although with the centre line deep fulvous), or of 

 some of the varieties of S. Berdmorei. Under surface from 

 chin to anus brilliant fulvous, the bases of the liairs whitish 

 on the chest, greyish on the belly. Hands and feet grizzled 

 with orange and black. Tail-hairs broadly ringed with 

 bright fulvous and black, the tips of the hairs fulvous. 

 Premolars ^, at least in the milk-dentition ; incisors deep 

 orange-red above, rather paler below. 



Dimensions of the type (a slightly immature male in 

 skin) : — 



Head and body 245 millim. ; tail imperfect; hind foot 42 ; 

 combined length of three upper true molars 6'2 ; distance 

 from front of ?^ to back of incisor 15'2.
