This spiny mouse seems to differ from any of the described 

 species by its colour and its comparatively non-spinous nape, 

 in which respect it approaches A. Louisa' of N. Somali. 

 From the latter, besides its greater spininess, it differs by its 

 much lieavier teeth, the breadth of m^ being in ^4. mullah 

 \Q> mm. and in A. Louisa' \-',\.

The Wardair specimen is peculiar in several respects, but 

 as it is an abnormally old individual nothing can be done 

 Nvith it until we have further evidence as to the cranial deve- 

 lopment that takes place with age. 



The presence or absence and the time of eruption of the 

 posterior molars in the Heterocephalus group are also rendered 

 somewhat dubious by these most valuable specimens, but 

 imtil further material is available I do not propose to commit 

 myself to an opinion on the subject.
