most thoroughly explored for marine species; and Aroos-

It is with the hope of stimulating further research, especially 

 in those counties where little or no work has been done, and 

 thus extending our knowledge of the distribution of the shells of 

 ]\Iaine, that this list is published. Hoping to publish a revised 

 list later on, we shall be glad to receive specimens or records of 

 shells from all sections of the State.
