I find no other localities for this mollusk recorded in the inter-montanic 

 region, except that Mr. Lord mentions finding a " Zonites like electrina, 

 Fort Colville, Columbia River "; and Mr. Binney accredits it to the 

 Central Province. All my own localities were at the foot of mount- 

 ains, and in each case the animals were found in the wet shaded ground 

 beside running water. In the valleys of the Animas and La Plata, tbey 

 were very abundant under logs. It is distributed over the United States 

 generally, except on the Pacific coast.
