PRELIMINARY NOTES ON THE MOLLUSCA OF ST. ANDREWS AND 



VICINITY, NEW BRUNSWICK. 



By John D. Detweiler, B.A. (of Queens University). 



St. Andrews College, Toronto. 



From the middle of August, to the middle of Sept. 1912, 1 spent at the Biolog- 

 ical Station, St. Andrew's, N.B., working on the distribution of the Mollusca. 

 Collecting was done by dredging and by collecting on the shore at low tide. On 

 account of the limited time spent in the work and the want of a complete supply 

 of literature for reference the number of species identified was not very large. 

 The writer hopes to complete the work in a later season.
