NOTES. 



HELIX PISANA MULL., IN CALIFORNIA. While in San Diego 

 in July 1914 Mrs. Kate Stephens, Curator of the San Diego 

 Society of Natural History, showed me 4 specimens of a snail 

 that had been found in the garden of Miss Scripp's home at La 

 Jolla. These shells were not like any local snails and she be- 

 lieved them to be European, as some of the plants or bushes in 

 the garden had been imported from Belgium. 



This summer Mr. Allyn G. Smith of Redlands informed 

 me that there was colony of Helix pisana Mull., at La Jolla and 

 he gave me a set of shells which he had collected in December 

 1914. Mr. D. L. Emery of National City, has also collected 

 from the same colony and reports them quite plentiful even 

 though he went after them in August and had to dig them out.
