218 REPORT ON NATIONAL MUSEUM. 



iuteresting species, which have never been obtained by the summer 

 party at this station. 



The other important accessions to this department during 1882, de- 

 manding special notice, are as follows: 



From Mr. Alexander Agassiz, Cambridge, Mass., a first installment 

 of the duplicates of the Blake exploring expedition, consisting of 13 

 species of Anthozoa, 25 species of Sponges, 5 species of Orinoids, 8 spe- 

 cies of Cephalopods, and 33 species of Crustaceans. 



From Dr. F. C. Dale, U. S. N., and Mr. Pierre L. Jouy, naturalists of 

 the U. IS. steamer "Palos," engaged in surveying on the coasts of Japan 

 and China, a large and exceedingly interesting series of marine inver- 

 tebrates, chiefly Crustaceans and Radiates, from those regions. This 

 collection derives additional value from the fact that it replaces, in 

 part, old collections of the Museum burnt at the great Chicago fire of 

 1871. In that conflagration the National Museum lost its alcoholic 

 collection of Crustaceans, obtained by the United States exploring ex- 

 pedition under Captain Wilkes, and described by James D. Dana, and 

 nearly the entire collection of marine invertebrates secured by the North 

 Pacific exploring expedition, which was being studied and described by 

 Dr. William Stimpson, naturalist to that expedition, and director of the 

 Chicago Academy of Sciences, where both collections were stored. The 

 specimens from the latter expedition had been described only in part, 

 and the Palos collection will probably be found to contain much new 

 material when it has been ])roperly worked over. It is entirely in alco- 

 hol, and in a fine state of preservation. 



The U. S. steamer "Alliance," in search of the " Jeannette," has sent 

 a,lcoholic collections of marine invertebrates, obtained by dredging and 

 towing in the vicinity of Spitzbergen, August, 1881. 



Dr. William H. Jones, U. S. N., IJ. S. steamer "Wachusett," has fur- 

 nished a fine collection of Crustaceans and Echinoderms, from the west 

 coast of British Columbia and Alaska. 



The United States Signal Service party at Point Barrow, Alaska, have 

 supplied littoral marine Crustaceans and fresh-water Entomostraca 

 from the vicinity of the signal station. 



The U. S. steamer "Alert" has sent twenty-five samples of soundings 

 from the vicinity of the Bonin Islands, Pacific Ocean. 



Dr. Thomas C. Craig, U. S. N., U. S. steamer "Jamestown," has con- 

 tributed a small collection of marine invertebrates from the South At- 

 lantic. 



Lieutenant Elliott, U. S. Marine Corps, has sent one tank of alcoholic 

 marine invertebrates from the Arctic regions. 



Mr. Ernest Wilkinson, midshipman, U. S. N., has furnished a small 

 collection of Sea-urchins and Crustaceans from the Arctic regions. 



The Museum Nacioual de Eio de Janeiro, Brazil, has sent, in ex- 

 change, a complete collection of all the known species of Brazilian corals, 

 consisting of 144 specimens, and 34 species, procured between Maran-
