THE NAUTILUS. 

 DEEDGING OFF BAN DIEGO, CALIFOENIA. 



BY C. W. GRIPP. 



During the summer of 1908 the writer made a dredging trip out- 

 side of the entrance to San Diego harbor, dredging in from 15 to 60 

 fathoms of water. The following list includes all the species obtained 

 and also a few deep-water species secured from fishermen. This 

 locality is very rich in molluscan life, especially in smaller forms. 

 Including the Opisthohrunchs my list of San Diego shells contains 

 over 600 species and varieties. I am greatly indebted to Dr. Wil- 

 liam H. Dall, Mr. Paul Bartsch and Prof. F. "W. Kelsey for assist- 

 ance in determining doubtful species.
