REPORT ON THE ECHINODERMS. 



By Hubert Lyman Clark. 



The curatorial work has consisted in the rearrangement, accom- 

 panied by relabeling, of certain large genera, additional material 

 of which has made a revision practicable. The identification, 

 labeling, and cataloguing of the accessions has kept pace with 

 their receipt. 



More than 1,000 specimens were added during the year, includ- 

 ing representatives of fifty-six species previously lacking. The 

 most notable accession was a series of nearly 500 specimens re- 

 ceived from the South African Museum, Cape Town, in return 

 for the identification of material; this series included forty-eight 

 species and eleven genera new to the collection, with paratypes 

 of twenty-three new species. Other lots received in return for the 

 identification of material were a series of 141 crinoids and Echini, 

 including four genera new to the collection, from the vicinity of the 

 Straits of Florida, presented by the University of Iowa, through 

 Prof. C. C. Xutting; 135 specimens from the Bermuda Biological 

 Station, presented by Prof. E. L. Mark; and eighty-eight speci- 

 mens from the Labrador and Xew England coast, presented by 

 the Boston Society of Natural History. A very valuable collec- 

 tion of fifty-seven specimens from the Falkland Islands was gen- 

 erously given by Dr. Richard H. Wace. A small but valuable 

 collection from Samoa was the gift of Mr. John W. Mills. From 

 the estate of the late Rev. H. W. Winkley, forty-nine specimens 

 from the New England coast were received. Additional accept- 

 able gifts were presented by Messrs. W. F. Clapp, W. A. Hilton, 

 R. T. Jackson, A. G. Mayer, and D. Thaanum. 



The preparation of an extensive report on the echinoderms of 

 South Africa occupied a considerable part of the year. A report 

 on the holothurians collected during Mr. Agassiz's expeditions in 

 the Tropical Pacific, on the Albatross in 1899-1900 and 1904- 

 1905, was also completed, and a similar report on the sea-stars of 

 the same expeditions was partially prepared.
