the Shells of Maine, 333 



H. fraternOf Say. I prefer to retain Say's name for this 

 shell, believing it to be distinct from H. monodon, of the West- 

 ern States. It is quite common in forests, and on hill-sides in 

 open pastures, under old logs and stumps and leaves, in damp 

 places. 



H. pulchella, Muller. This pretty little species may be 

 found at any time during the warm season, in gardens and 

 by the way-side in this city, wherever it can find a wet chip 

 lar^re enoui^h to hide itself under. 



H, alteniaia, Say. Shell gregarious, abundant. Several 

 hundred, old and young, are frequently found within the space 

 of a few inches, in old logs and stumps. It inhabits all parts 

 of the State, including some of the islands in Casco Bay. It 

 probably inhabits all the States in the Union, as I have received 

 specimens of it from both sides of the mountains, and recently 

 several specimens from Alabama, through professor Brumby. 



H. striateUa, x\nthony. Found in great abundance in all 

 parts of the State, in and about old decaying wood, and under 

 damp leaves. 



H. lineata. Say. Found in com.pany with the preceding, 

 but not plenty. 



H. mdeniata, Say. Mr. True has found this species at 

 Monmouth ; it however appears to be rare. 



H. arborea, Say. This is common everywhere, under stones, 

 and about old stumps and logs. I cannot perceive any char- 

 acters by which to distinguish this species from H. lucida, 

 Drap. of Europe. 



H. lahyrinthica, Say. Found sparingly, in company with 

 most of the small species. 



H. electrina, Gould. i\Ir. True has found this species at 

 Monmouth ; it is, however, rare. 



H. chersina, Say. I have found a few specimens of this 

 species in company with H. lahijrinthica. If not the same 

 thing, it is certainly very nearly allied to H. fuha, Muller. 



H. sayi, Binney. This fine species is found at Monmouth 

 and at Bangor.
