REPOBT OF NATIONAL MUSEUM, 1913. 63 



clatiire revised, fresh labels attached to the ftiitside of the jars and a 

 systematic arrangement effected. At the same time the card cata- 

 logue of these groups was brought down to date. The cataloguing 

 of current accessions was promptly attended to, and that of several 

 large collections which had fallen in arrears was made up. A number 

 of sets of duphcate specimens was prepared for distribution to schools 

 and colleges, and much time was spent in selecting material for the 

 exhibition series. 



Ikliss Mary J. Rathbun, assistant curator, finished the preparation 

 of a report on the stalk-eyed crustaceans of the Dutch West Indies, 

 based on a collection made by Dr. J. Boeke in 1905, which is to be 

 published by the Dutch Government in a series dealing with the 

 resources of those islands. She also identified most of the Japanese 

 crabs sent for that purpose by the University of Tokyo, and con- 

 cluded the working up of the large collection of PhiUppine crabs of 

 the famiUes Ocypodidae and Grapsidse, in the same connection study- 

 ing and determining all of the specimens belonging to the same fami- 

 Hes contained in the general ^Museum collection. A report on the 

 Philippine specimens is nearly ready for pubUcation. !Mr. Austin H. 

 Clark, assistant curator, conducted investigations upon a number of 

 collections of recent crinoids, mostly received from abroad, some of 

 which were finished, while others are still in progress, and he also 

 completed revisions of a number of families and genera of crinoids. 

 In cooperation with Mr. Frank Springer, he prepared a treatise on 

 crinoids for a new edition of Zittel's Paleontology, and a part of the 

 section on the Holothuroidea for the same pubhcation was furnished 

 by him. Dr. Harriet Richardson, collaborator, continued her studies 

 on isopods and identified a number of specimens from various sources, 

 including small collections obtained by the Bureau of Fisheries 

 steamer Albatross on the west coast of Mexico in 1911, and by the 

 French Antarctic Expedition, the latter collection belonging to the 

 Museum of Natural History in Paris. 



The resources of this division are so great and so diversified that 

 it would be quite impossible to depend upon its small staff for all of 

 the research work necessary for the entire classification of the col- 

 lections placed in its custody. For this reason it has long been the 

 pohcy to seek the help of zoologists specializing in the various groups 

 of marine and other aquatic invertebrates wherever they may be 

 located, and it has also been the good fortune of the Museum to 

 receive such assistance freely and almost wholly without other 

 obhgation than a right to share in the division of the duplicate 

 specimens yielded by each collection as it is studied. A fuU state- 

 ment of this cooperative work would involve the names of most of 

 the prominent experts of the world in the subjects covered by the
