literally covered with these snails. This species 

 does not drill holes in oyster shells as does Urosalpinx 

 and Eupleura but is a scavenger and eagerly devours 

 dead animals of various kinds. 



The eggs, small white bodies, are common in 

 May and June and may be found attached to sea 

 weeds or floating plants. The species is known 

 from the Gulf of St. Lawrence to Florida; the mud 

 flats of Xew Jersey are perhaps its favorite home.
