Report on the Echinoderms^ by A. Agassiz. 

 During the past year the arrangement of the collection of 

 Echinoids has been finished by Mr. A. Agassiz. The systematic, 

 generic, and faunal collections, as far as it was possible, have 

 been completed. The collection, owing to want of room, is 

 stored in drawers ready for exhibition. The alcoholic portion 

 has been put into glass jars, and is at present arranged syste- 

 matically in the northeast room. Mr. Theodore Lyman has 

 catalogued all the Ophiurans which had been added to the col- 

 lection of the Museum during his absence from the United 

 States. Mr. A. Agassiz has also commenced the final arrange- 

 ment of the Starfishes, and continued the catalogue of the 

 Holothurians. 



The additions to the Echinoderms have been numerous and 

 valuable. Among the most interesting should be mentioned a 

 large collection obtained in exchange from the Smithsonian, 

 containing many species collected by Dr. Stimpson in the North 

 Pacific Exploring Expedition ; quite a complete collection of 

 British Echinoderms obtained from Dr. Stimpson ; an important 

 collection of living and fossil Echinoderms from the Chevalier 

 Verany, of Nice. The collections of Mr. Cooke, at Zanzibar ; of 

 Captain Putnam, on the West Coast of South America ; of Mr. 

 Moore, from the Irish Sea ; of Mr. Bickmore, from Beaufort, 

 N. C. ; and the collection of Mr. Salmin, from Japan ; Dr. 

 Sternbergh, from Panama. Of special value for a faunal collec- 

 tion is the large series of dry Echinoderms sent to the Museum 

 by Mr. Van Brunt, from Acapulco. Professor Valenciennes, of 

 the Jardin des Plantes, has sent a small but invaluable collec- 

 tion of Echini, which having been carefully compared with the 

 original specimens of Lamarck in the Jardin des Plantes, may 

 be considered as types of the species described in the Hist. Nat. 

 des Anim. sans Vertebres. A large number of duplicates have 

 been sent to different institutions ; three large collections are
