AP0DEMUS 



r97 



equal to one-half width of palate in same region. Pattern of 

 enamel folding essentially as in Apodemus sylvaticus, but 

 re-entrant angles of first lamina of m 1 without rudimentary 

 supplemental loops ; postero-external border of crown of m 1 and 

 m 2 with small though evident supplemental tubercle appearing in 

 worn teeth as a narrow outward-projecting loop ; outer ledge 

 and rudimentary tubercles of m 1 and m 2 better developed than in 

 A. sylvaticus, those of the second tooth nearly as large as those of 

 first, a condition rarely if ever occurring in the smaller animal.

Specimens examined. — Thirty-five, from the following localities : — 



Montehbgho : No exact locality, 6. 



Albania : Northern Albania, 8.

Remarks. — While Apodemus epimelas is very unlike the other 

 European members of the genus it closely resembles A. mystacinus 

 Danford and Alston from Asia Minor, differing chiefly in its 

 somewhat larger skull and heavier teeth (see measurements in 

 Table opposite), and also in the slightly duller, less buffy ground 

 colour of upper parts.
