of the Geological Society of America and Scripps Institution of Oceano- 

 graphy. The results of this cruise, including the paleontology and some 

 biology, are summarized in Anderson, etal.{\950). A later list of the 

 mollusks collected by this expedition can be found in Emerson and 

 Puffer (1957), and a further reworking of some of the geological data can 

 be found in Byrne and Emery (1960). Several expeditions were also made 

 into the Gulf of California by the Allan Hancock Foundation with the 

 VeleroIII and IV (Eraser, 1943). The biological data from these 

 cruises has been published at various times by Garth, Haig, Ziesen- 

 HENNE, Grau, Soule and others in the Allan Hancock Pacific Expeditions 

 Reports, Volumes 1 to 23. Information on stations collected by the Allan 

 Hancock Foundation subsequent to 1942 can be obtained from the 

 Foundation. 



Finally, the last major collecting cruise into the Gulf of California prior 

 to the present "Vermilion Sea Expedition" was the "Puritan-American 

 Museum of Natural History Expedition" in 1957. A general 

 account of the expedition can be found in Emerson (1958), who has also 

 written several short papers on the Pleistocene mollusks of the region, 

 resulting from the efforts of this expedition. Squires (1959) gives an ex- 

 cellent account of the corals collected on the Puritan cruise and Soule 

 (1961) has discussed the bryozoans. 



Small collections of mollusks have been made from time to time by 

 moUusk collectors at Puerto Peiiasco, San Felipe, Guaymas, La Paz and 

 Mazatlan, Mexico, although references are too numerous to be given here. 

 Dr. S. Stillman Berry has described many new species of mollusks from 

 the Gulf and has discussed their biology in his Leaflets in Malacology 

 (privately printed and available from Berry). Notes on Gulf of California 

 mollusks can also be found in the Annual Reports of the American Malaco- 

 logical Union, Pacific Division. The collections of Mrs. Faye Howard of 

 Pacific Palisades, California have provided the basis for lists by a number 

 of people, including McLean (1961), and her notes on the reproduction 

 of marine gastropods from the Gulf of California were made available to 

 the author through Professor Gunnar Thorson. One other expedition to 

 the Gulf of California in recent years should also be mentioned, "The 

 Ariel Expedition", undertaken by members of the Conchological Club of 

 Southern California. Using a shrimp boat, a number of excellent collections 

 were taken on the middle and outer shelf portions of the Gulf. An account 

 of some of the mollusks taken can be found in Shasky (1961). 



Although scattered, there seems to be considerable literature available 

 on the biology of the Gulf of California. Not mentioned above are also a
