REPORT ON THE CRUSTACEA. 



By Walter Faxon. 



Since the last Annual Report of the Curator of the Museum 

 the collection of Crustacea has been enriched through exchange 

 with Mr. Charles Chilton of Christchurch, New Zealand, and 

 Prof. B. F. Koons of Mansfield, Conn., and through gifts from 

 Prof. D. S. Jordan and Mr. A. W. Butler. 



A representative collection of Crustacea has been presented 

 by the Museum to the University of Wisconsin, to repair the 

 loss of the old collection, which was burned. 



The Cymothoids belonging to the Museum, which have been 

 for some time in the hands of Messrs. Schiodte and Meinert of 

 Copenhagen, have been restored during the past year. This 

 collection formed an important part of the material upon which 

 these gentlemen based their elaborate Monograph of the 

 Cymothoidse, published at Copenhagen in the " Naturhistorisk 

 Tidsskrift," 3d Series. 



The determination and cataloguing of the collection has gone 

 on as far as the time at the disposal of the Assistant would 

 allow. In connection with this work the Assistant has published 

 " Descriptions of New Species of Cambarus ; to which is added 

 a Synonymical List of the Known Species of Cambarus and 

 Astacus," in Proc. Amer. Acad. Arts and Sci., Vol. XX. pp. 

 107-158, December, 1884 ; " A Revision of the Astacidas," in 

 Mem. Mus. Comp. Zool., Vol. X., 186 pp., 10 plates ; also a 

 "List of the Astacidse in the U. S. National Museum," in Proc. 

 U. S. Nat. Mus., Vol. VIII.
