/O MUSEUM OF COMPARATIVE ZOOLOGY 



There are probably 5000 species of mollusks of which we have some 

 sort of type material. With few exceptions, all of the collections ob- 

 tained during the past thirty-five years have contained some type 

 specimens; before that the proportion of type material was much 

 greater. 



When fully catalogued there will be more than 160,000 lots, rep- 

 resenting about 30,000 species and subspecies. 



Many persons have gathered rich material during their explora- 

 tions, among them T. Barbour,' who has made about thirty foreign 

 collecting journeys; W. S. Brooks, who has collected shells for the 

 Museum on most of his trips; W. M. Mann, who has enriched the 

 collection with species from the Solomon and Fiji Islands of his own 

 taking; and the Honorable W. C. Forbes, who donated an exceed- 

 ingly large series of Philippine mollusks, largely collected for him by 

 C. M. Weber, while Forbes was Governor General of the Philippine 

 Islands. 



Important additions have been received from H. L. Clark from 

 the West Indies and Australia; Arthur Loveridge, mainly from 

 Africa; Jack Sandground, from Africa; W. S. Schroeder from the 

 deep water areas off New England; Joseph Bequaert from Yucatan 

 and Africa; A. F. Archer from New England and Cuba. The many 

 journeys by W. J. Clench with friends of the Department and former 

 members of the staff" have also yielded rich material, especially from 

 the Bahama Islands. The Mu.seum has also recently received the 

 great collection of Cuban Mollusks, given by Dr. Pedro Bermudez. 



Earlier records show the accession of material from Gulick, Ben- 

 son, Bland, Binney, Cisneros, Cooke, Dohrn, Garrett, Godman, 

 Morelet, Hirase, Pike, Prime, Putnam, Wright, Yates, and a host of 

 other naturalists who in their time carried on extensive exchanges 

 w'ith the Museum. 



The past few years have again seen increased activity in the line of 

 exchanging with many of the present day naturalists. 



Expeditions such as the Hassler and Thayer, and explorations by 

 the vessels "Albatross" and "Blake," have contributed largely in the 



• Many of the very large West Indian collections made by Dr. Barbour, the 

 members of his family and other associates were made possible only because of 

 the transport facilities offered by Mr. Allison V. Armour's Research Yacht 

 Utowana. The Museum is very greatly in Mr. Armour's debt.
