report, was continued, and some drawings and photographs to be 

 used as illustrations were prepared. Miss Rathbun also completed 

 a paper on the brachyuran crustaceans obtained during the recent 

 Albatross cruise in the Northwestern Pacific, and began the study 

 of an important collection of crabs from the Gulf of Siam. trans-

 Arrangements were made to publish a valuable manuscript prepared 

 some forty years ago by the late Dr. William Stimpson on the 

 Brachyuran and anomuran crustaceans obtained mainly on the North 

 Pacific exploring expedition of 1853 to 1858. It will be issued in 

 the Miscellaneous Collections of the Smithsonian Institution. Dr. 

 Harriet Richardson, collaborator, worked up and reported on the 

 isopod crustaceans collected during recent cruises of the Fisheries 

 steamer Albatross in the North and South Pacific Ocean. Mr. 

 Austin H. Clark, naturalist of the steamer Albatross during the 

 North Pacific expedition of 1906, spent several months in the study 

 of the crinoids secured on that cruise, as well as the specimens in the 

 general collection of the Museum, and prepared descriptions of a 

 number of new species for publication. 



A considerable number of specimens of the genus Heliaster of star- 

 fishes from the Galapagos Islands were lent to Dr. Hubert L. Clark, 

 of the Museum of Comparative Zoology, for use in a revision of the 

 genus. The collection of pedunculate cirripeds was sent to Dr. II. A. 

 Pilsbry, of the Philadelphia Academy of Sciences, who has kindly 

 offered to report on this group as represented in the National Museum. 

 Arrangements were made with Mr. J. A. Cushman, of the Boston 

 Society of Natural History, to work up the foraniinifera from the 

 deep-sea dredgings and soundings of the Fisheries steamer Albatross 

 in the Pacific Ocean, and a considerable amount of material has al- 

 ready been sent to him. 



In the division of plants Doctor Rose, associate curator, continued 

 his studies of Mexican plants and of the cacti, on which he has been 

 engaged for some years. Mr. Maxon, assistant curator, made good 

 progress in his work on the American ferns, giving special attention to 

 those of Cuba and Jamaica, and Mr. Painter, aid, continued his in- 

 vestigations of water lilies. Over a thousand plants were lent for 

 study to both American and European botanists. 



In the division of geology and mineralogy nearly all of the time 

 available for research work was devoted to the study of meteorites 

 and associated phenomena. Six papers on this subject by the head 

 curator, Doctor Merrill, three being in collaboration with Mr. Tassin, 

 assistant curator of mineralogy, were prepared and, with one excep- 

 tion, were printed during the year. At the close of the year Doctor 

 Merrill was engaged in an exhaustive study of the problems presented
