THE PACIFIC CONCHOLOGICAL CLUB. 



BT CHESTER STOCK, UNIVERSITY OF CALIFORNIA. 



There has long been felt the need of an organization on the Pacific 

 coast which would be valuable to the amateur collector, to the con- 

 chologist, and to those using conchology as supplementary to their 

 studies in zoology and palaeontology. With such a combined pur- 

 pose in view, an organization known as the Pacific Conchological 

 Club has recently received its initial start at the University of Cali- 

 fornia. It is to be hoped that the beneficent effects of a society of 

 this sort wil\ stimulate still further interest in conchology as a sci- 

 ence on this coast. 



The occasional meetings which will be held will bring the con- 

 chclogist in touch with the invertebrate zoologist and palaeontologist 

 and with their problems in which conchology so often plays an im- 

 portant role. Furthermore, it is the desire of the society to ulti- 

 mately establish at the university one of the largest collections of 

 shells on the coast. This collection will be augmented from time to 

 time by the results of excursions to the beaches and through the 

 medium of exchange. 



On April 23d a meeting was held at the University of California, 

 at which time Mr. B. L. Clark reported on the molluscan fauna of 

 Bolinas Bay, California. A representative collection of this fauna 

 was obtained on a recent excursion held under the auspices of the 

 society. Other features of the program were a discussion on the 

 factors controlling the distribution of mollusks by Dr. F. B. Sumner, 

 and a report by Prof. W. J. Raymond on a thesis entitled, " Varia- 

 tions in the Forms of Thais found on the Pacific Coast," by Bertha 

 M. Challis, of the University of Washington.
