Measurements. — Average of seven specimens from the type locality : 

 total length 139; tail vertebrae 40; hind foot with claws 19; hind foot 

 without claws 17.S. For details see table, page 109. 



Specimens examined. — Seven, all from the type locality. 



Remarks. — In Evotojnys hercynicus sueciciis the colors are dark- 

 ened about as in E. h. rubidus, but the dorsal red area is at the same 

 time distinctly narrowed. The difference is readily seen when a num- 

 ber of specimens are laid with the sides in contact. In E. h. riibidus 

 as in E. h. hercyniczis, the gray of the sides is then quite hidden, 

 while in E. h. suecicus it is still conspicuously visible.

 Type locality. — Abbeville, Somme, France. 



Geographic distribution. — Humid coast district of Belgium and 

 northern France, probably extending north to Denmark. Limits of 

 range quite unknown. 



General characters. — Size as in E. hercyjiicus hcrcyniczis., but 

 tail relatively longer, forming 33 to 37 percent of total length. Red 

 dorsal area in winter pelage broad and diffuse, dull ferruginous, not 

 intermixed with gray. Belly heavily washed with buff. Tail dark 

 brown above. 



Color. — Summer pelage not known. Winter pelage : red dorsal 

 area diffuse and ill defined, extending from eyes nearly to base of tail 

 and tending to spread slightly over sides. In general color it is very 

 nearly mars brown or Prouts brown, though occasionally approaching 

 russet, the general effect residting from a mixture of cinnamon rufous, 

 vinaceous rufous, and black. Sides and cheeks dull brownish buff 

 thickly sprinkled with black. The color of sides fades insensibly into 

 that of back and abruptly into the strongly buff-tinged gray of the 

 belly. The buff wash on the ventral surface is variable but always con- 

 spicuous. On sides and belly the slaty underfur appears irregularly 

 at the surface. Face slightly darker than cheeks. Tail sharply bi-
