* This list has been compiled from various authors. 
This long list will probably be modified as the different faunas are 
studied more intensely. However, it suffices to show that the known 
fauna of this region is considerably less than the actual fauna. 
The diserepaney between the number of known forms and the 
number obtained by the Survey is due in part to the fact that little 
attention was given to shore collecting. Mollusks were obtained, 
however, at the following shore stations: Bonita Point, Sausalito, 
Fort Point, Key Route Pier (Oakland), Point Richmond, Red Rock, 
and MeNear’s Landing. 
In the discussions that follow only the material obtained by the 
Survey will be considered unless the contrary is stated. As a matter 
of convenience the fauna obtained in the open ocean off the Golden 
Gate will be designated as the ‘‘outside’’ fauna in contrast to the 
““‘hay’’ fauna.
