666 THE LAND SNAILS OF NEW ENGLAND. 
CARIBOU (Rangifer Caribou Aud. and Bach.). Caribou 
are quite plenty a little north of here, about Ragged 
Lake, Black Brook, ete. Caribou live principally on 
moss, but eat some twigs. It is faster, I think, than either 
deer or moose; of these two, the deer is the faster. The 
meat of a caribou when dressed weighs, I judge, from 
two hundred and fifty to three hundned. pounds. 
Derr (Cervus Virginianus Boddaert.) Deer are not 
very plenty about here. They browse “moose-bush,” fir, 
cedar (Arbor vitæ), willow, swamp maple, and lynois 
bush; in summer they like lily-pads, leaves of trees, and 
grass. I think that, like the moose, the deer generally 
bears two young. 
[We have introduced the scientific names of the animals mentioned 
by Mr. Clapp, and would refer those of our readers who wish for in- 
prehensive and invaluable work of Professor BAIRD D, on the ‘‘Mam- 
mals of North America,” forming the eighth volume of the Pacific Rail- 
road Reports, published by order of Congress in 1857. — EDITORS. |

Tue following species, though minute, are very char- 
acteristic, and with the aid yt the engravings, but little 
trouble will be encountered in identifying them. For- 
~ merly included under the old genus Pupa, they are now 
_ Separated under a distinct genus called Leucochila. But 
slight differences are noticed between the soft parts of the 
a smene to be described, and those given previously.
