indicus, and macrurus belong to Ratafa ; the species (except 

 rvjigenis and lohriah) from ferrugineus to atridorsaUs and 

 also Macdellandii to Sciurvs ; and " ^S." rujigenis, luhriah^ 

 palmarum ^ tristriatus^ Layardi^ suhlineatus^ and Berdmorei 

 to Funamhulus. The excessively long-nosed Chinese forms, 

 Davidianus, Pernyi, and pyrrhomerus^ are also, of course, 

 members of the last-named group. 



GltphoTES*, gen. nov. (of Sciuridce). 



Size small. Colour-pattern as in Sciurus notatus. Skull 

 with the muzzle excessively short and broad, the nasals 

 parallel-sided, nearly as broad behind as in front ; nasal 

 opening flattened from above downwards. Postorbilal pro- 

 cesses small, situated far back. Anterior end of zygoma 

 more vertical than in Sciurus, its base ojiposite the anterior 

 edge of m.\ Lower jaw weak, the coronoid minute, not 

 surpassing the condyle in height ; condyloid process slender, 

 drawn out backwards ; angular process narrow. 



Upper incisors very broad transversely, shallow antero- 

 posteriorly, their depth not exceeding their breadth, their 

 Iront faces very convex ; as an additional peculiarity they are 

 curved slightly outwards, so that along their inner edges they 

 diverge from each other for their terminal millimetre, and 

 their outer edges, when viewed from in front, can be seen to 

 be distinctly concave. Lower incisors exceedingly broad and 

 shallow, divergent, their front faces smoothly concave, their 

 edges ■\vorn into broad chisel-shaped blades, of which the outer 

 corners are longer than the inner. Cheek-teeth very small 

 in proportion, their pattern as in Sciurus ; premolars f. 



Glyphotes simus, sp. n. 



Size about half that of Sciurus notatus orestes. Character of 

 fur, proportions of ears and limbs, and colour throughout 

 almost precisely as in S. notatus, if one of the bufFy-bellied 

 Bornean examples of that species be selected for comparison. 

 The white lateral band is, however, rather broader and more 

 strongly marked, especially anteriorly. But, with this trivial 

 exception, the resemblance is astonishingly complete, althougii 

 the small size and stumpy nose would always serve to distin- 

 guish the species externally. Upper surfaces of fingers and 

 toes, sides of nose, rims of eyes, and edges of ears bufFy 

 yellowish; indistinct whitish postauricular patches present;

 incisurs.
