and the M. sanguineus groups are not very sharp. The race which is to be described 

 now, as it cannot be identified with any known form, appear3 to be intermediate, and 

 its subspecific name is added to the species name sanguineus which is much older 

 than ochraceus. 



Upper parts of the whole animal grizzled, the hair being broadly annulated 

 with huffish white, sometimes more inclining to ochraceous, and dark brown to blackish. 

 The annulation of the hair tends to produce about 2 mm. broad, somewhat wavy, 

 blackish transverse stripes which are visible on the posterior two thirds of the body, 

 and sometimes as far forward as above the shoulders. The pale bands between 

 these look broader than the black in consequence of the arrangement of the hair, 

 although on the single hairs the dark rings are broader than the light. The hairs 

 are about 13 — 15 mm. on the anterior, 15 — 17 mm. on the posterior parts of the 

 back, single hairs being somewhat longer. Each hair has three alternating light and 

 dark rings, the base being light, and the tip dark. The head is more finely, and 

 the tail more coarsely grizzled. The hair of the latter has 4 or 5 pale rings the last 

 of which often reaches the tip. The legs are grizzled, but the fingers are more or 

 less uniform buff. The lower side is different in different specimens. A fully adult 

 but not old male is uniform rather rufous buff all over the lower surface and on the 

 inside of the hind legs, but the chin and lower neck is somewhat grizzled separated 

 by a uniformly buff-coloured patch on the throat. In another male and a female, 

 both old, the whole of the lower neck is grizzled, and the middle of the thoracic 

 region is also grizzled. The ventral region and the inside of the legs which are uni- 

 formly coloured are dull buff. The general arrangement of the grizzled areas is 

 similar to these latter specimens in a young male but the colour is still duller, pale 

 greyish buff. The black tip to the tail is longest in the old male, about 13 cm. to 

 the tip of the hairs, in the others it is only 7 cm. The hair of the tail is from 30 

 to 40 mm. The dimensions of the four specimens show some variability especially 

 with regard to the length of the tail: 



O" old length of head and body about 27'/2 cm, of tail without hair 32 cm.
