hibernate so carefully that one is amazed when spring opens to find 

 such armies of them. 



Living along with Snccinece 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, Macroctjlis concava and Zonites 

 fa/vus also occur, Pupce 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 

 Carychnmi 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 

 gleaned much of interest regarding the 

 hibernation of the different snails there 

 found. Here are my notes for the 7th of January this year : 



" Particularly numerous at this time are H. palHata, 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. palUata. 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. albolahris, usuallv so 

 plentiful in the warm season is now apparently 

 very scarce ; not over a half dozen live ones found 

 this winter, and they were among the leaves, par-
