60 Praeger — The Marine Shells 



inhabits a region. Many bivalves burrow deeply in sand and mud, and flourish 

 out of reach of the naturalist's dredge. "When they die, the shells come up to 

 the surface, and are thus thrown on shore by the waves, or taken by the dredge, 

 in a fresh state. 



In conclusion, the writer expresses a hope that the following list may 

 prove a reliable foundation for a more complete and extended paper on the 

 Marine Mollusca of the North of Ireland, and that by showing the incomplete- 

 ness of the record, it may encourage other workers to give some of their 

 attention to this interesting subject.
