JOURNAL OF MAMMALOGY 
The beavers, which have always persisted, are now represented by 
two rather prosperous colonies in the Diamond region. In addition 
to these the work of isolated individuals is occasionally found on both 
the Dead and the Swift Diamond and their tributaries. 
The otter is also found, particularly in the northern parts of the 
state, although the species is rapidly being exterminated. 
At present the authentic record of New Hampshire mammals oc- 
curring within the state during the past five years, includes all the 
large species known to have occurred formerly with the exception of 
the timber wolf, the northern gray fox and the woodland caribou. 
The last record in my possession of the timber wolf is that of a speci- 
men taken in the White Mountains in 1887. In regard to the north- 
ern gray fox, the only record which I have is that of the type specimen 
described by Merriam in 1903, which was taken at Marlboro, New 
Hampshire. Tracks of a small herd of four woodland caribou have 
been reported from near the Canadian line in the Connecticut Lake 
region by an old trapper. This report, however, has not been con- 
firmed. While a specimen was obtained in Houlton, Maine, in 1893 
and tracks seen as late as 1896 (Recreation, volume IV, 1896, page 
140) no caribon are known to have occurred within this state for a 
number of years. 
The following is a preliminary checklist of the mammals known to 
have occurred within the state during the five year period from 1915 to 
1920. The list is exclusive of the families Muridse and ZapodidsB, and 
the orders Insectivora and Chiroptera. Sufficient collecting has not 
as yet been done to make even a preliminary report on these groups. 
1. Phocssna phocsena (Linn). Common Harbor Porpoise. — Comparatively 
abundant off Portsmouth Harbor. 
2. Odocoileus virginianus borealis (Miller). Northern Virginia Deer. — Com- 
mon throughout the state. 
3. Alces americanus Jardine. Moose. — Found only rarely in the northern 
part of Coos County. 
4. Sciurus hudsonicus (Erxleben). Northern Red Squirrel. — ^Very common 
in the northern part of the state. 
5. Sciurus hudsonicus loquax Bangs. Southern Red Squirrel. — Common 
throughout southern part of the state. 
6. Sciurus carolinensis leucotis (Capper). Northern Gray Squirrel. — Com- 
mon throughout southern two-thirds of the state. 
7. Tamias striatus lysteri (Richardson). Chipmunk. — Locally common 
throughout the state. 
8. Marmota monax preblorum Howell. Woodchuck. — Very common through- 
out the cultivated regions.
