34 ANNUAL REPORT OF THE 



REPORT ON THE ECHINODERMS. 



By Hubert Lyman Clark. 



The routine work of the year has consisted of the determination 

 and special labeling of type material, the moving of the collection 

 of dry Echini, and the incorporation of the numerous accessions 

 into the study collections. The types among the crinoids are now 

 all determined, but among the starfishes the work has progressed 

 more slowly, so much of the material is old and so few specimens 

 have any indication of their use as types. The transfer of the dry 

 Echini into new and far more commodious quarters is a decided 

 improvement and greatly increases the accessibility of that collec- 

 tion. 



The additions for the year amount to 1,417 specimens, repre- 

 senting 170 species, of which 52 species and 10 genera are new to 

 the collections. From the United States National Museum, 775 

 specimens of 108 species were received in return for identification 

 of material; of these, 418 were received through the courtesy of the 

 American Museum of Natural History. From the U. S. Bureau 

 of Fisheries, also in return for determination of material, 41 speci- 

 mens of 6 species have been received. A very valuable collection 

 of 29 specimens, representing 25 species, 13 new to the collection 

 and 11 paratypes, was received from the Western Australian Mu- 

 seum, in return for a report on their echinoderms. The Imperial 

 University, Tokyo, sent three cotypes of Echini in exchange. 

 From Mr. A. J. Sidney, 39 beautifully prepared dry specimens 

 were purchased. A desirable series of crinoids, starfishes, and 

 brittle-stars was donated by Mr. J. Gabriel, Melbourne. Other 

 gifts have been received from Miss Mary R. Rotch, from Drs. 

 R. T. Jackson and Th. Mortensen, and from Messrs. W. F. Clapp, 

 T. M. Douthart, and George Nelson.
