obtained certain species that had never been reported in this 

 vicinity before. 



The list of species given below is the largest ever reported 

 from Bolinas Bay. It includes a number of forms that had 

 heretofore not been reported as far north. Two other lists of 

 species from this locality have been published, one by Robt. E. 

 C. Stearns in 1866, the other by W. M. Woods in 1897. Mr. 

 Stearns published a list of eighty-three marine species. 1 Mr. 

 Wood, to whose paper reference has already been made, listed 

 seventy-nine species. The number of species in the collection 

 of the Pacific Conchological Club is ninety-seven. To this 

 may be added those listed by Stearns and Wood and not found 

 in the Pacific Conchological Club collections, making a total 

 of one hundred and twenty-seven species from this locality.
