No. 1705 Broadway San Diego, California. 
21:1522 Mollusca of: San Diego county, California. 
The following is a reprint from above, in alphabetical order, 
of all the shells reported to date from San Diego county, Cal., in- 
cluding those reported from north and south of San Diego, tho 
not actually taken in our territory, as far as known to the writer. 
Some species doubtles appear under two or more names, but 
synonyms are eliminated as far as we recognize them, but many 
changes will probably be noted when we receive the latest revis- 
ions of the nomenclature on which Drs. Dall and Bartsch have 
been working for years. We will appreciate receiving additions 
and corrections, to be given in future issues of this work.
