28 ANNUAL KEPORT OF THE 



REPORT ON THE CRUSTACEA AND MOLLUSCA. 



By Walter Faxon. 



With the help of Miss E. B. Bryant, I have overhauled the 

 whole of the alcoholic mollusks stored in the basement of the 

 Museum. Block tin numbers have been placed in each jar, cor- 

 responding to the numbers in a new catalogue prepared by Miss 

 Bryant. Certain of the dry collections of especial value by virtue 

 of the work expended on them by specialists, and of the number 

 of types they comprise, have also been catalogued by Miss Bryant 

 under my supervision. Among these are the Godman collection 

 of Central-American land-shells, forming part of the material 

 worked up by Von Martens for the Biologia Centrali-Americana, 

 Henry Suter's New Zealand shells, and the Blake Expedition Mol- 

 lusks collected in 1877-80, and identified by W. H. Dall and 

 K. J. Bush. I am convinced that only in this way can large col- 

 lections of type material be made permanently safe and at the 

 same time easily available. 



During the year Miss M. J. Rathbun has published in the 

 Museum "Bulletin" (Vol. XXXIX., No. 5) an account of the 

 Crustacea collected by Mr. Agassiz in the Maldive Archipelago in 

 1901-02. Her report comprises description of six new species, 

 the types of which are now in our Museum. 



The Assistant would here acknowledge with thanks the gifts 

 to the collections received from Messrs. A. Agassiz, T. Barbour, 

 J. H. Blake, Owen Bryant, A. S. Pearse, J. H. Sears, R. K. Smith, 

 and E. B. Wilson. Exchanges of specimens have been negotiated 

 with the United States National Museum, and loan of material to 

 the United States National Museum and to Mr. T. Thompson of 

 Clark University.
