NOTES ON THE MAMMALS OF PRINCE EDWARD 
ISLAND. 
ROBERT T. YOUNG. 
THE following is an annotated list of mammals observed 
during a three weeks’ stay in Prince Edward Island in the 
fall of 1897. 
I. Sciurus hudsonicus gymnicus. — A fairly common species. 
My specimens agree pretty closely in size with those from New 
Brunswick and Nova Scotia. It is interesting to note that skins 
from this section average decidedly smaller than those from 
Ontario (Miller)! and Labrador (Bangs)? This seems rather 
strange, considering that in grading off into the southern form, 
loquax, it increases rather than diminishes in size. Average 
of six specimens from New Brunswick (American Museum of 
Natural History, New York): total length, 277; tail, 110; hind 
foot, 43. Average of ten from Digby, Nova Scotia (Bangs): 
total length, 296; tail, 113 ; hind foot, 45. Average of two 
from Prince Edward Island (Young): total length, 282; tail, 
113; hind foot, 45. Average of four from Hamilton Inlet, 
Labrador (Bangs) : total length, 309; tail, 120; hind foot, 48. 
Average of eight from Ontario (Miller) : total length, 309; tail, 
121; hind foot, 47. Average of eight Sciurus h. loquax from 
Liberty Hill, Connecticut (Bangs) : total length, 318 ; tail, 134 ; 
hind foot, 47. ; 
2. Mus musculus. — One specimen was caught in a bushy 
field, largely grown up with Juncus, near Georgetown. 
3. Peromyscus canadensis. — Two specimens were all that I 
secured, both being taken beneath a stump fence bordering 
some wet woodland, near Kensington. As both are imma- 
ture I cannot state with certainty the variety, but they appear
