c?.K. 7G^; ? . K. 76a, K. 76 6. Tabora. 



A form darker iu colour than any other subspecies of 

 abyssinicus hitherto described. 



No trace of a dorsal stripe. General colour between 

 seal- and clove-brown. The light rings on the hairs much 

 reduced. When viewed from in front, these rings are very 

 inconspicuous, so that the pelage appears remarkably dark, 

 especially on the head and shoulders. Viewed from behind 

 the light rings show up more^ producing a grizzled greyish- 

 brown appearance. Halfway down the back a russet tinge 

 appears, which increases over the flanks and root of the tail. 

 Head the same colour as fore part of the back. Ears seal- 

 brown. Fore feet dark seal-brown. Hind feet tinged with 

 russet. The usual bicoloured tail. Under surface of body 

 brown washed with grey.

A, a. tenebrosus is remarkable for the darkness of its 

 pelage, which is much darker than in nubilans. Its nearest 

 neighbours are the light-coloured A. a. neumanni to the east 

 in Irangi and A. a. muansce to the north, the colour of which 

 is said by Matschie to be not unlike Peters's figure of 

 Pelomys fallaxj though more drab.
