fauna is nearest the channel entrance and is dominated numerically 
by Armandia bioculata. The central part of the bay consists of fine 
sediments and is dominated numerically by Heteromastus filoformis 
and Exogone lourei. At individual stations C. capitata and Pasta 
alata may occur in large numbers and thus alter the community 
structure. The Chorro and Los Osos Creeks fauna is dominated 
numerically by S. benedicti and C. capitata; these two species are 
known to be tolerant of brackish waters elsewhere (Woodwick, 1953). 
Dr. Keith H. Woodwick, Fresno State College, identified the 
specimens of the genus Polydora, sensu lato, for which aid we are 
grateful.
