ears as in ajcJotis, unusually broad, seraicircularly rounded 

 off above, and narrowly edged all I'ound with yellow, tliis 

 yellow edge interrupted here and there by the dark central

 Molarlform teeth, as in cijclotis, subcircular in outline, with 

 m^ and ni^ conspicuously smaller than, respectively, p* and p4, 

 but all teeth much heavier, particularly broader, than in the 

 related species : p' (length and breadth) of type (between

 (l*2xl'l). Colour of fur peculiarly mottled above, as in 

 JS. cyclotis, but much darker : individual hairs of back seal- 

 brown at extreme base (for about 5 mm.), then very pale 

 huffy wood-brown (for 5—6 mm.), with short (2 mm.) dark 

 brown tips; the mottled appearance of the colour of the head

 hairs; a narrow and somewhat ill-defined dark brown spinal 

 stripe along posterior half of back; breast and belly pale 

 greyish drab in centre, flanks fawn.
