size or proportions. Some specimens of Evotomys gapperi have a 
total length of from 110 mm. to 160 mm., but in the vast majority 
this measurement falls between 120 mm. and 140 mm. Only about 
two dozen specimens of E. fuscodorsalts are at present known from 
the region south of Hamilton Inlet, and, as might be expected, most 
of these are under 140 mm. in length. Mr. Allen has, however, 
recorded one that measures: total length, 152; tail vertebrae, 46; 
hind foot, 20.5 ; thus reaching well toward the maximum of E. gap¬

given by Mr. Allen is: total length, 133 (127-140) ; tail vertebrae, 
38 (35-41) ; hind foot, 20 (19-20.5). The five specimens from the 
north shore of Lake Superior average: total length, 133.8; tail
