The only place in the Sound where red squirrels were found 
was Port Nell Juan. Here they were observed only by Hassel- 
borg, who secured one and saw two others. A prospector who 
had spent several years in the vicinity of the Port knew of but 
a single colony and this one had recently become very much 
reduced in numbers. About the heads of the passes leading 
into the interior from Valdez they are said to be more common. 
These localities represent their extension from the Copper River 
drainage. Red squirrels are not known to occur on any of the 
islands of the Sound. 
Citellus plesius ablusus Osgood. Nushagak Ground Squirrel. 
Three specimens, one from Valdez Narrows and two from 
Thompson’s Pass. Two of these have the coloration of plesius. 
The other specimen has a grizzled tail like ablusus. The skulls 
have the small flat bullae of ablusus, but in size they approach 
plesius. The nasals, however, are short as in ablusus. The form 
is thus intermediate, perhaps nearest ablusus. 
Marmota caligata (Eschscholtz). Hoary Marmot. 
Secured at Cordova Bay and Valdez Narrows and on Hinch- 
inbrook and Montague islands. Nine specimens are in the col- 
lection from these localities. The species occurs everywhere 
on the mainland along the shores of the Sound. It is also 
found on the higher islands where a definite timber-line occurs, 
but is much less abundant in these localities than on the adjacent 
mainland. A few were seen on Hinchinbrook Island, where a 
single specimen was obtained. On Montague Island they were 
observed at both Zaikof and Hanning bays, living in burrows 
at the edge of timber-line. They were very timid and whistled 
much less frequently than those observed on the mainland. 
Unless very much frightened they remained silent, their whist- 
ling note not being used as a warning to their neighbors but 
rather as an indication of sudden fright. A very few were 
seen on Knight Island. Hawkins, the only other large island, 
apparently lacked them. They were found at Cordova Bay 
from the cliffs alone the coast to timber-line, but at other local- 
ities they were noted only at timber-line or above.
