Report on Radiates, by A. Agassiz. 



During the past year Mr. Niles has been engaged in arrang- 

 ing the Crinoids, and in making diagrams for the Museum 

 Catalogue. For the sake of examining the fine collection of 

 Burlington Crinoids, he has spent his vacation at Burlington, 

 where Dr. Barries, Charles Wachsmuth, Esq., and Dr. Thieme 

 gave him all the facilities to be desired, and allowed him the 

 freest use of their collections for examination. Mr. A. Agassiz 

 has continued the arrangement of the Starfishes, which was 

 begun last year, as far as time could be spared from the general 

 care of the Echinoderms received. Mr. Verrill hag been occu- 

 pied in making the faunal arrangement of the Polyps of the 

 eastern shores of North America, and in making a Faunal List 

 of the collections of the Anticosti expedition. He has also 

 taken the general care of the Polyps during the beginning of 

 the year. For the Acalephs, the few specimens which have been 

 added to the collection, have been at once catalogued by Mr. 

 A. Agassiz. 



The printing of the first part of the Illustated Catalogue of 

 the Museum, containing the Ophiuridae, by Lieutenant-Colonel 

 Lyman, is now completed. The Catalogue of Acalephs, by Mr. 

 A. Agassiz, is in the press. The Third Part of the Museum 

 Bulletin, containing the lists of Polyps sent in exchange by 

 Mr. Verrill, has been published and distributed with the Annual 

 Report of the past year. Mr. T. G. Cary has very kindly under- 

 taken to prepare from the Museum Catalogue the faunal sheets 

 of Radiates ; he has finished the Ophiurans, and has made some 

 progress with the Polyps also. 



Among the most interesting additions to the Radiates are, for 

 Echinoderms, the collection sent by the Imperial Museum of 

 Vienna, through Dr. Redtenbacher from the Red Sea. Also a 

 small collection from Mr. James Barnard, as well as the collec- 

 tion secured with the Gray Fund from Mr. A. Agassiz, made at 

 the Society Islands. For the Acalephs, the collection of dupli- 

 cates sent by the Smithsonian Institution, of Hydroids, collected 

 by Dr. Stimpson, in the North Pacific Exploring Expedition, 

 and the collections of the Anticosti expedition, are the most 

 interesting. 



In Polyps, the most valuable invoices are a small collection 

 of typical species, sent by Professor Edwards, from the Jardin
