insertion of the tail, 12 inches; of the tail itself 6 inches. It was a 
female, and its stomach contained the half-digested remains of a frog. 
There are two stuffed specimens of a larger species of Mink preserved 
in the Museum at New York: perhaps this may be M. Cuvier’s Mustela 
Vison, since the Baron could hardly have overlooked the character which 
led him to devise the genus Mustela. 
(17.) Mustela Martes (Linn.) The Pine Marten. 
The ae Marten ay common about Bristol, and I have seen many 
specimens, al! differing from the Canadian animal in the patch of yel- 
low on the throat being uniform in colour and figure; whereas in the 
Canadian Pine Martens the patch is irregular in shape, and spotted with 
brown, the head is also grey and fox-like. There is a Marten described 
in Silliman’s Journal as the Fox-like Marten, and those in this district 
appear to belong to that species or variety, for it must be granted that 
individuals are to be found approaching very near our species in the 
particulars above noticed, 
(18.) Mustela Canadensis (Linn.) The Fisher or Pekan. 
Length from the nose to the insertion of the tail 19} inches; of the 
tail 155 inches. The specimen was a female. 
(19.) (Mephitis) Americana.** The Skunk. 
(20.) Lutra Canadensis (Sabine.)* Canada Otter. 
(22. A.) Canis Lupus griseus.* The gray Wolf. 
(26.) Canis (Vulpes) fulvus (Desmarest.) The American Fox. 
(26. y.) argentatus (Desmarest.) Black or Silver Fox. 
(30.) Felis Canadensis (Geoffroy.)** Canada Lynx. 
(33.) Caston fiber (Linn.) The Beaver. 
Now very rare, though their old embankments are to be still seen on 
most streams. ee 
(34.) Fiber zibethicus (Cuvier.) The Musk-rat or Musquash. 
(35.) Arvicola riparius (Ord ?) Bank Meadow Mouse. 
Length of the head and body 5} inches ; of the tail 2 inches. This is 
the most common Mouse in the fields of Upper Canada, making shallow 
‘ burrows under every fallen tree, and also under rails, hay-ricks, &c., and 
in the winter beneath the snow. The female makes her nest of grass, 
under logs. It frequents also the barns.
