HYGROMIA HISPIDA (LINNJEUS) IN MAINE. 



BY N. W. LERMOND. 



In 1904 I found a snail considerably smaller in size than Polygyra 

 frnterna Say, and very numerous on walls of old lime quarries, on 

 wooden sidewalks and on the under sides of rocks from the lime 

 quarries at Rockland, Knox County, Maine. Specimens sent Dr. 

 Pilsbry for identification were pronounced by him Hygromia hispida 

 (Linn.), and the first record for this species for the state of Maine. 



In his 1898 list of " Land Shells of America North of Mexico," 

 on page 3, Prof. Pilsbry gives Hygromia hispida (Linn.) as found 

 at Quebec and Levis, Quebec, Canada " a species of northern 

 Europe, imported." In 1905 I found them quite as plentiful in and 

 about old lime quarries at Thomaston, and in 1906 collected them in 

 a garden in the same town under cabbage plants. They literally 

 " swarmed " on the ground and on the under side of the cabbage 

 heads. This garden is on the banks of " Mill River," and near a 

 lime kiln. 



This season I found them just as numerous and they are by far 

 the most abundant species in this locality in the Rockland and 

 Thomaston localities, but have not as yet found them elsewhere in 

 the county, although they quite likely are already established in the 

 lime quarries of Camden and Rockport.
