lighter than the head as in true vulcanorum, but still percep- 

 tibly so. Yellow spot on sides of nose particularly well 

 marked. Under surface yellowish grey, more as in some of 

 the -forms of emini. 



Incisors thicker than in other specimens of vulcanorum, 

 1*6 mm., therefore about as in emini. Molais comparatively 

 large. 



Dimensions of type (measured in flesh) : — 



Head and body 125 mm.; tail 151; hind foot 30*5; 

 ear 11. 



Skull: greatest length 35; condylo-incisive length 31*5; 

 upper tooth-series exclusive of p 3 6.

 number 328. Collected 3rd January, 1907, by Douglas 

 Carruthers. One specimen only. 



This animal, while obviously distinct enough to deserve a 

 subspecific name, is of somewhat doubtful relationship, and 

 more specimens will be needed before the question can be 

 settled. While its comparatively thick incisors and large 

 molars are more as in T. emini, its general colour and light- 

 edged ears approach those of T. vulcanorum, to which, mainly 

 on geographical grounds, I provisionally refer it. But I 

 should not be surprised if it turns out to be instead a southern 

 subspecies of T. emini.
