T^pe localifi/.—Neav Fexhe-Slins, banks of the Maas, 

 Belgium. 



Geographical (listribution.— 'Eastern Belgium and north- 

 western Germany ; probably north-eastern France also.* 



Diagnosis. — Similar to C. cricetus cricetus, but skull noticeably 

 smaller, its condylobasal length about 45 mm. ; form of brain- 

 case as in the typical race. 



Measurements. — External measurements of two adult males 

 from Tirlemont, Liege, Belgium : head and body, 212 and 218 ; 

 tail, 50 and 47; hind foot, 35 and 35 (dry, 33 and 33-4);

Specimens c.ramined. — Four, from tbe following localities : — 

 Belgium : Tirlemont, Liege, 3. 

 Germany : Brunswick, 1 (Eield). 



Remarks. — The status of this race is not satisfactory. The 

 Belgian specimens which I have seen show none of the 



* I have seen no Frencb specimens, but the form will probably prove 

 to be canescens. For account of recent cbanges in distribution in France 

 see Trouessart, Faune Mamm. d'Europe, p. 159.
