EVOTOMYS 



639 



side ; red dorsal area broad, not well defined from bufly grey 

 sides of body. 



Colour. — Summer pelage : dorsal stripe dull ferruginous 

 slightly varied with light wood-brown and much darkened by a 

 uniform sprinkling of black-tipped hairs, fading rather abruptly 

 into the light wood-brown of face, cheeks and sides ; rump wood- 

 brown tinged with red in median line and forming no noticeable 

 contrast with colour of back ; underparts pale drab-grey, washed 

 to a varying degree with yellowish brown and irregularly 

 darkened by appearance at surface of slaty under colour ; feet 

 dull white, a dark shade at inner side of ankle ; tail sharply 

 bicolor, dark brown above, whitish below. 



SJcull. — The skull is decidedly larger and more heavily built 

 than that of Evotomys glareolus ylareolus and the other small 

 races. Zygomata heavy, abruptly spreading antei'iorly, the 

 greatest zygomatic width at level of front of molar series. 

 Postorbital processes distinct but very small. Brain-case 

 moderately high and rounded, distinctly rectangular in outline 

 when viewed from above. Nasals squarely truncate posteriorly a 

 little in front of tips of nasal branches of premaxillaries. 



Teeth. — The teeth are larger than those of true Evotomys 

 glareolus, and the third upper molar usually has only two 

 re-entrant angles on inner side. Otherwise they show no 

 peculiarities.
