Fairly abundant and of general distribution both 
in Buzzards Bay and Vineyard Sound, from 
low-water mark down. Living specimens 
occasionally dredged at 2 to 8 fathoms; shells 
much more common and occurring at all 
depths, being frequently occupied by hermit 
crabs. Verrill ’s statement that this species is 
“generally much more abundant [than P. 
;is species and certain other small Naticida;, some of the records 
arred stations, on the other hand, were referred to Messrs. Dali
