the voles from the island and that a few years ago he had noted 
the complete disappearance of the shrews also. Some trapping 
was done on two other islands used as fox farms, one situated 
at the entrance to Drier Bay and another near the east coast 
of Hoodoo Island; but both of these were found to be without 
any evidence of the presence of small mammals, although islets 
near them were inhabited by the representative species of the 
region. Green Island, which has until very recently been used 
for fox farming, has lost all its indigenous mammals except 
Sorex obscurus alascensis, and this species is much reduced in 
numbers. The absence of Sorex on Naked and Storey islands 
is difficult to account for except on the basis of fox depredations. 
Seventeen species of mammals were secured within the drain- 
age area of the Sound. Specimens of all the forms known to 
oceur on the islands were secured; but we were less fortunate 
in capturing the mainland species. The mainland forms known 
to occur but not secured by us were: Oreamnos, Fiber, Castor, 
Lepus, Lynx, Vulpes, Gulo, Mustela, and Ursus dalli. Oreamnos 
is found occasionally about Cordova Inlet, Valdez Inlet, and 
Eaglek Bay, but not on the Kenai Peninsula. Fiber is said 
to oceur sparingly in Lowe River near Valdez. Castor was 
formerly found in the meadows at the head of Cordoya Inlet 
where the remains of dams are still to be seen. Lepus occurs 
during favorable seasons in numbers near Valdez and about the 
head of Cordova Inlet. Vulpes, Gulo, and Lynx oceur spar- 
ingly except during seasons when Lepus is abundant, and then 
these carnivores also become numerous. Mustela americana is 
widely distributed but is seldom taken. 
Sciurus hudsonicus petulans Osgood. Glacier Red Squirrel. 
The two specimens secured are referable to this form. An 
adult male from the head of Port Nell Juan is considerably 
larger than any in the series from Glacier Bay, the feet being 
especially large. The dimensions of this specimen (no. 910) 
are: length 370 mm., tail 145, hind foot 54; skull: Hensel 38.5, 
zygomatic breadth 28.5, length of nasals 15.5, width of nasals 
7.5. Another specimen secured at Thompson’s Pass, near Valdez, 
is somewhat smaller and nearer the average of petulans.
