hibernate so carefully that one is amazed when spring opens to find 
such armies of them. 
Living along with Succinee are H. thyroides and alternata ; shells 
of the former quite pretty, some of them delicate 
pink color, and a number of specimens are encir- 
cled with two or three bands of white, seem- 
ingly eroded. Macrocylis coneava and Zonites 
fulvus also occur. Pupe are scarce ; I have only 
seen a few contracta and pentodon. In the 
wettest parts of the woods, in the moss, great numbers 
of Pomatiopsis lapidaria can be gathered; also 
Carychium exiguum; and in the cove and river in 
the near vicinity are twenty or more species of fresh water shells, 
many of them of excellent quality.

During the early part of the present winter, as frosty days were 
quite the exception, I visited “ Almont” 
frequently for collecting, all of them 
delightfully successsful trips. | Have

found. Here are my notes for the 7th of January this year: 
“ Particularly numerous at this time are HH. palliata, though not so 
easily found as in summer. They are invariably closed with the 
epiphragm, lying aperture upward, looking very pretty when first 
exposed to the light, their pearly white lips contrasting beautifully 
with the dark epidermis. Old bark nests seem to be a favorite place 
for them to congregate for winter. Sometimes they will be found 
singly, often five or six grouped together; and at times as many as 
twenty or thirty distributed about a single little vicinity. A situa- 
tion of this sort is often chosen by H. monodon (fraterna) ; this 
species can thus be found to the extent of twenty or more individuals 
in a cluster wintering along with H. palliata. Once in a while the 
collector is pleased by the finding of a large Zonites fuliginosus 
\ buried his whole depth in the ground, and 
nothing visible save the membranous covering 
over the aperture. H. albolabris, usually so 
plentiful in the warm season is now apparently 
very scarce ; not over a half dozen live ones found
