OUTSTANDING COLLECTIONS 



There are a number of very lovely private collections in the United 

 States, some devoted wholly to marine species, others limited to land or 

 fresh-water types. Many represent years of collecting, others an expenditure 

 of many thousands of dollars. To mention a few would be to slight many 

 another. The best private collections are in California, Florida, Connecticut, 

 the New York area and Massachusetts. As time passes, private collections 

 are either sold, lost or left to some public or university museum, so that today 

 we find the largest collections housed by public or endowed institutions. 



The United States National Museum, under the Smithsonian Institution 

 in Washington, D.C., contains what is undoubtedly the largest mollusk col- 

 lection in the world. Until Dr. Paul Bartsch, now retired, was curator, it 

 was second in size to that of the British Museum in London. Today, this 

 study collection contains over 9,000,000 specimens, 600,000 lots or suites and 

 in the neighborhood of 36,000 species and subspecies. Its curator at present 

 is Dr. Harald A. Rehder, and his associates are Dr. J. P. E. Morrison. 



The Museum of Comparative Zoology at Harvard College, Cambridge, 

 Massachusetts, has risen to second place in the United States within the last 

 fifteen years. It is famous for its well-kept collection of about 7,000,000 

 specimens, 300,000 lots and approximately 28,000 species and subspecies. Its 

 present curator is Dr. William J. Clench, noted for his development of stu- 

 dents in mollusks. Dr. Ruth D. Turner is assistant curator. 



The Academy of Natural Sciences of Philadelphia, Pennsylvania, is 

 third or fourth in size and contains an unusual amount of valuable material. 

 Its present curator. Dr. Henry A. Pilsbry, has been with the institution for 

 over sixty years, and he has contributed more to our science than any other 

 worker. He was preceded by two equally famous curators, George W. 

 Tryon and Thomas Say, America's first malacologist. The author is the 

 present incumbent of the Pilsbry Chair of A4alacology. 



In the Midwest, one of our largest fresh-water and land collections is 

 located at the Museum of Zoology, University of Michigan, Ann Arbor. 

 Dr. Henry van der Schalie, an expert on fresh-water clams, is the curator. 

 The Chicago Museum of Natural History in Illinois contains a small but 

 adequate collection and is under the care of Dr. Fritz Haas, a scientist well- 

 versed in many phases of malacology. 



There are no very large study collections in southeastern United States, 

 although one of the finest exhibit collections is on display at Rollins College 

 in Winter Park, Florida. It is well worth visiting, for the collection is beau- 

 tifully lighted and arranged and is instructively labeled. Of equal brilliance, 

 the Simon de Marco collection of rarities is housed in the commercial Florida 

 Marine Museum near Fort Myers, Florida.
