Collecting American Se ash ells 69 



Among the leading American collections that in the California Academy 

 of Sciences in Golden Gate Park, San Francisco, stands foremost in western 

 United States. It is a large and well-kept collection, supplemented by an 

 excellent library. Drs. G. Dallas Hanna and Leo Hertlein have in the main 

 been responsible for its successful growth. The Paleontology Collection at 

 Stanford University contains a large series of recent and fossil mollusks. It 

 is particularly strong in material from the Pacific northwest. Its present cura- 

 tor. Dr. Myra Keen, is one of our outstanding malacologists who specializes 

 in marine bivalves. A very large collection of marine mollusks is housed at 

 the San Diego Natural History Society, Balboa Park, San Diego. The 

 Museum of Paleontology, University of California, Berkeley, also has a very 

 large collection.
