EVOTOMYS 257 



with pinkish-buff and darkened by the slaty hair-bases. Glandular 

 patches present on flanks, but not conspicuous. Ears well clothed 

 with rufous hairs. Hands and feet buffy white above ; soles 

 hairy. Tail shorter than in E. r. smithii, well clothed with short 

 stiff hairs which do not completely conceal the annulations ; 

 bicoloured, brown above (blackish at tip), cream buff below. 

 Young specimens are much darker than adults. 



Skull with the braincase, as in E. r. smithii, longer and less 

 nearly square than in E. r. nifocanus ; distinguished from that 

 of all other subspecies by its rather wider palate and slightly 

 larger auditory bullse. 



Cheek-teeth, in adult stages of wear, as in other subspecies; 

 but as in E. r. smithii m^ in young stages of wear tends to be more 

 complex than is usual in young E. r. rufocanus and E. r. shanseius, 

 the ephemeral vestiges of the fourth inner and outer salient 

 angles being usually clearly developed. 



Size is apparently as variable in this subspecies as in others; 

 the smallest skull with rooted teeth seen has a condylo-basal 

 length of 25-7 mm. ; on the other hand in the largest skull 

 examined, with a condylo-basal length of 27-3 mm., m"^ is still 

 growing. Fully mature skulls may therefore easily reach a 

 condylo-basal length of 29 mm. or more. 



For external mid cranial dimensions see tables at end of 

 volume.
