52 Observations on the Terrestrial 



European Liraaces are found only directly on the coast. All the 

 species of land pulmonates of the State with the exception of T. 

 hortensis, P. minuscula, H. cellaria, P. badia, Isthmia milium and 

 the European Limaces occur at Bethel on the Androscoggin river 

 seventy miles inland from' Portland ; and, with the exception of 

 T. dentifera, M. concava, H. multidentata, P. asteriscus, L, contracta 

 and L. corticaria are also found in the immediate vicinity of Port- 

 land. Margaritana arcuata I have noticed to be more common in 

 brooks near the coast. Anodontas reach their highest state of derel- 

 opment in mill ponds and canals ;. Lampsilis radiata is generally 

 found in ponds, and Strophitus undulata and TJnio complanatus- 

 are found in nearly all bodies of water. 



The following we quote from the Second Annual Keport upon the Natural 

 History and Geology of the State of Maine ; 1862, page 132 ; it is contained in 

 the report of Marine Zoology by C. B. Fuller. " On the Brown Cow and Eagle 

 Islands (Casco Bay) which are nearly destitute of vegetation, I found the 

 following land shells in abundance. Helix nemorahs, Helix albolabris and Succinea 

 obliqua. On Eagle Island, a short distance from the above, Helix alternata 

 occurs in great numbers. Almost every island in the bay has a mollusk peculiar 

 to itself, and coincident with its soil or flora. Eagle Island bearing spruce and 

 fir produced Helix alternata, while one of the Goose Islands with a hard wood 

 growth produced Helix albolabris abundantly^"
