Stephens’ notes from Rodman Bay, Baranof Island, are: 
“Common in grass patches along the beach in a few places. 
They had the habit of burrowing and carrying earth out to the 
entrance of the burrows, which were in light loamy soil. They 
covered some traps with earth freshly brought out. I have 
noticed this burrowing habit elsewhere only at Idaho Inlet, 
Chichagof Island.’’ At Peril Strait Stephens found them at 
one place only and there difficult to secure. Dixon has the 
following to say about the habits of this species at Idaho Inlet, 
Chichagof Island: ‘‘Meadow mice were abundant in the salt 
marsh meadows, where they cut trails two or three inches wide 
along the bottoms of little gutters. I watched one throw up a 
mound of dirt about a foot across and four inehes high. The 
mouse would start a hole and then turn around and push the 
dirt out just as a gopher does. This was the first time that I 
had ever seen meadow mice burrow in the ground to such an 
extent and I never saw them throw up ‘mole hills’ before.’’ 
At Hooniah two were taken by Dixon above timber-line, at 
which locality no runways were observed below 2300 feet alti- 
tude. In the vicinity of Port Frederick the species was found 
by Dixon abundant in a meadow five miles north of camp. 
Microtus yakutatensis Merriam. Yakutat Vole. 
This species was secured in abundance on both shores of 
Glacier Bay. <A series of thirty are in the collection. These 
although not differing in color from sitkensis have the small 
foot of yakutatensis with the typical form of which they doubt- 
less intergrade in color somewhere along the coast north of 
Glacier Bay. In coloration this series is readily distinguishable 
from the much grayer yakutatensis. No reliable skull differ- 
ences, however, were detected between the island and the main- 
land material. The first lower molar has normally four closed 
triangles, but variations to five on one first lower molar or the 
other are not rare. 
On the west shore at Coppermine Cove, Dixon found them 
common in patches of strawberry plants near the beach but 
none were found in the elevated interior country. About Bart- 
lett Cove Stephens found them common in grassy situations on
