INTRODUCTION 
The United States Fisheries Steamer ‘‘ Albatross’? was commis- 
sioned in Oetober, 1911, by the Bureau of Fisheries, to make a bio- 
logical survey of San Francisco Bay. The operations were directed 
by a board consisting of Dr. F. B. Sumner, naturalist, Professor ©. A. 
Kofoid, of the University of California, and Commander G. H. Bur- 
rage, U. S. N., succeeded by Lieutenant-Commander H. B. Soule, 
U.S. N. The field work began on January 30, 1912, and continued 
until April 7, 1913, when the last dredge haul was made. 
A portion of the results of this survey dealing with the physical 
conditions within San Francisco Bay has been published in a joint 
paper by Dr. F. B. Sumner, Dr. G. D. Louderback, Mr. W. L. Schmitt, 
and Mr. E. C. Johnston (1914). Discussions and detailed data are 
given regarding the temperature, salinity, depth of the water, and the 
character of the bottom for the various stations occupied by the 
“* Albatross.’’ These data serve as the basis for ecological studies now 
being made of the different groups of marine organisms obtained 
during the survey. 
The mollusean material obtained by the various types of dredges 
employed, and by shore collecting at a limited number of localities, 
was preserved in alcohol or formalin and shipped to the Zoological 
Laboratory of the University of California. The dredging material
