THOMSON : MOLLUSCA OF BRISTOL COUNTY, MASS. 37 1 



P. striate! I a Anthony. — New Bedford, Dartmouth, Westport, 

 and Tiverton. Common. 



P. asteriscus Morse. — Westport. Very rare; under dead 

 maple leaves near swampy places. 



P. lineata Say. — Westport. Not common ; under chips and 

 stones around old houses. 



Ferussacia subcylindricaL. {=Zua lul>rica Leach). — West- 

 port and Tiverton. Under bits of wood and boards in 

 dry locations. I can see no difference between this and 

 European species — there are slight variations among all. 



Pupa muscorum L. (^-P. i^adm Adams). — Dartmouth and 

 Westport. Common ; but not one in 50 has the parietal 

 tooth. W. G. Binney decides this and the European 

 species to be identical. Morse thinks them diverse {vide 

 Portland Soc. Jour.). Found only by me near the salt 

 water in old dead trees and stumps. 



P. pentodon Say. — Westport. Found near foot of trees 

 among moss and leaves near water holes. Rare. 



P. fallax Say (=^. marginatus, Pfr., Tryon, &c.). — Tiverton. 

 On the rocky ridge near Tiverton, Rhode Island, among 

 oak trees. Rare. 



P. armifera Say. — Tiverton. Rare; I found some near the 

 shore of Stafford Lake. I can compare to no other species. 



P. contracta Say ? — Westport. Rare and very local. More 

 elongate than the type. 



P. corticaria Say. — Found some years ago on the island of 

 Naushon, Buzzard's Bay, under the bark of an old beach 

 tree. Not yet found in Bristol county. 



Vertigo gouldi Binney. — Westport and Tiverton. Not 

 common. 



V. bollesiana Morse. — Rare. I found three specimens with 

 V. gouldi, which I think are the species of Morse. 



V. milium Gould. — Westport. Not rare. I have found them 

 mostly in the green moss hanging from white oak trees. 



V. ovata Say. — Westport and Tiverton. Common.
