REPORT ON THE CRUSTACEA. 
By WaAtter Faxon. 
SINCE last year’s report valuable accessions to the collection 
have come by gift from Dr. H. A. Hagen, Prof. W. Kovalevsky, 
Dr. C. O. Whitman, Prof. L. A. Lee, Prof. R. Ramsay Wright, 
Mr. C. L. Herrick, Prof. A. 8. Packard, Jr., and Mr. P. BR. Uhler. 
Of these a collection of Astacz, comprising all the known species 
from Siberia and Amurland, presented by Prof. W. Kovalevsky, 
deserves especial notice. Hxchanges have been made with the 
U. 8. National Museum, Boston Society of Natural History, Pea- 
body Academy of Seatac. and the Illinois State Pe hee of 
Natural History. 
Professor Baird being desirous of sending a collection of United 
States Crayfishes to the London Fisheries Exposition, I identi- 
fied for the National Museum a set made up from the material 
in both Museums, containing nearly every species described from 
this country. 
For the loan of valuable material during the year I have to 
thank the Director of the U. S. National Museum, the Council of 
the Academy of Natural Sciences of Philadelphia, Mr. P. R. 
Uhler of Baltimore, Prof. A. 8S. Packard, Jr. of Providence, the 
Curators of the Boston Society of Natural History, and the Pea- 
body Academy of Science, Salem, Prof. L. A. Lee of Brunswick, 
Me., Prof. 8. A. Clarke of Williamstown, Mass., Prof. O. P. Hay 
of Irvington, Ind., and Prof. 8. I. Smith of New Haven. 
A portion of the “ Blake” collections is still in the hands of 
Prof. A. Milne-Edwards, of Paris, and Prof. S. Il. Smith, of New 
Haven. In his ‘“ Recueil de Figures de Crustacés nouveaux 
ou peu connus,” 1” livr., Paris, April, 1883, the former has pub- 
lished figures of twenty-six of the remarkable species from these 
collections.
