p. 160. 



Type locality. — Near Fexhe-Slins, banks of the Maas, 

 Belgium. 



Geographical distribution. — Eastern Belgium and north- 

 western Germany ; probably north-eastern France also.* 



Diagnosis. — Similar to G. 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); 

 ear, 32 and 28. For cranial measurements see Table, p. 604. 



Specimens examined. — Four, from the following localities : — 

 Belgium : Tirlemont, Liege, 3. 

 Germany : Brunswick, 1 (Field). 



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

 Belgian specimens which I have seen show none of the 



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

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

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