2* Gratitude is herewith expressed for the generous help of the Department of Mollusks, Harvard 

 University, in the identification of the shells from He-4 and He-1. Primary references were Keen (1958) 

 and Olsson (1961) . Shell identifications by Willey and Stoddard for Co-2 and He-8 were made before eithei 

 reference was published.
