counts of the Philippine land shells of the genus Schlstoloma^ of the 

 recent and fossil mollusks of the genus Rissoina from the west coast 

 of America, and a number of smaller papers. He is at i^resent 

 engaged in the preparation of reports on the operculate land shells 

 of the Philippines, and the Eulimidoe and Tertiary Pyramidellidse of 

 America. Contributions by Mr, Austin H. Clark, assistant curator, 

 published during the year, comprised the first volume of a mono- 

 graph of existing crinoids, issued as Museum Bulletin 82, and other 

 papers on crinoids and onychophores. Mr. Clark also completed his 

 study of the crinoids collected by the Australian Fisheries Investi- 

 gation steamer Endeavour, and continued his investigations of the 

 material obtained by the Dutch steamer Siboga, the Danish steamer 

 Ingolf and the steamer Gauss of the German South Polar expedition, 

 besides preparing manuscript for a second part of Bulletin 82. Mr. 

 Waldo L. Schmitt, assistant curator, had nearing completion a report 

 on the decapod crustaceans of San Francisco Bay obtained during 

 the survey by the Bureau of Fisheries in 1912-13, and began upon a 

 study of the macruran crustaceans of the east coast of North Amer- 

 ica. Mr. William B. Marshall, assistant curator, was almost wholly 

 occupied with the care, identification, recording and arrangement 

 of the molluscan material received during the year. The limited time 

 available for research was devoted to the study of pearly fresh-water 

 mussels, and a short paper on three new species of Anodontoides 

 from Brazil was submitted. Mr. C. R. Shoemaker, aid, prepared an 

 account of the amphipods from the South Georgia (antarctic) ex- 

 pedition, and made progress with his studies of this crustacean group, 

 especially as represented on the east coast of North America. 



Dr. T. Wayland Vaughan, custodian of madreporarian corals, con- 

 tinued his investigations on West Indian and Pacific forms; and Mr. 

 H. K. Harring, custodian of the Rotatoria, contributed a paj)er on 

 specimens of that group from Panama, with descriptions of new 

 species. The work of Dr. C. W. Stiles, custodian of the helmintho- 

 logical collections, related to sanitation and the study of the para- 

 sites of school children, many such, both white and colored, having 

 been examined to determine the relative frequency of parasites 

 among them, their influence on the mental and physical development 

 of children, etc. 



The facilities afforded by the division were availed of by a number 

 of specialists and students, of whom the following may be mentioned, 

 namely, Mr. John B. Henderson, of Washington, who continued his 

 researches on Antillean mollusks; Prof. W. P. Hay, of Washington, 

 who spent some time in the preparation of a report on the crustaceans 

 found at the Beaufort Laboratory of the Bureau of Fisheries ; Mrs. 

 Kate S. Outwater, of Washington, who investigated the nepionic
