32 ANNUAL REPORT OF THE 



REPORT ON THE ECHINODERMS. 



By Hubert Lyman Clark. 



The principal work of the year has been the preparation of an 

 illustrated catalogue of the collection of brittle-stars (ophiurans), 

 to be issued in recognition of the publication in October, 1865, 

 of Lyman's Illustrated Catalogue of the same group. This work 

 has involved not only extensive overhauling of the collection for 

 the determination of type material, but also the description of 

 many new species hitherto catalogued as unidentified. 



A second work has been based on the echinoderms (except 

 the holothurians) collected by the Australian fisheries investiga- 

 tion steamer Endeavour, during the years 1909-1914, undertaken 

 for the authorities of the Australian Museum. A report, to appear 

 in the Memoirs of that Museum, has been prepared and the col- 

 lections have been returned to Sydney. For this service, the 

 Museum receives the first series of duplicates, consisting of 280 

 specimens of seventy-nine species, twenty-seven of which are new 

 to the collection, including twenty-one paratypes and representa- 

 tives of four new genera. This is one of the most important addi- 

 tions made in recent years. 



Work has been begun on the rearrangement of the collection of 

 spatangoid sea-urchins, in connection with the study of the 

 extensive series collected by the Albatross in the Pacific and 

 placed in Mr. Agassiz's hands for investigation. The remainder 

 of the year has been given to the identification, labeling, and 

 cataloguing of the accessions. 



Aside from the Endeavour collection, the most important addi- 

 tion of the year is a fine lot of Philippine echinoderms, including 

 a remarkable series of crinoids, generously presented by Dr. L. E. 

 Griffin, formerly of Manila. There are nearly 600 specimens of 

 ninety-three species, eighteen of which are new to the collection. 

 Mr. Joseph Gabriel of Melbourne has continued his liberal policy 

 of sending to the Museum such echinoderms as he gathers on his 

 collecting trips, and during the past year he has given 186 speci- 

 mens of nineteen species. Mr. E. C. Joshua, also of Melbourne.
