groups, and of others in which the facts obtained from a study of 

 the recent crinoids are applied toward the sohition of problems 

 especially in paleontology and oceanography. He likewise devoted 

 some time to the study of the onychophores and their geographical 

 distribution. 



Dr. Harriet Richardson Searle, collaborator, reported on the isopod 

 crustaceans obtained by the Fisheries steamer Albatross under the 

 direction of Alexander Agassiz, during the Pacific Ocean cruises of 

 1899-1900 and 1904-1905. Mr. Clarence R. Shoemaker, aid, prepared 

 an annotated list of the amphipod crustaceans collected in south 

 Georgia by Mr. R. C. Murphy, and has begun work on the amphipods 

 of the east coast of the United States. Miss Lilian C. Cash, cata- 

 loguer, gave some attention to the alcyonarians, preparing a series of 

 175 microscopic mounts of spicules, and beginning the identification 

 of the species in certain groups. Mr. H. K. Harring, of the Bureau 

 of Standards, devoted his spare time to the study of rotifers, in- 

 cluding the mounting of a large number of slides for the Museum, 

 and completed a report on the material obtained in the Panama 

 Canal Zone by Dr. C. Dwight Marsh. 



Much research work was done for the division during the year by 

 distinguished naturalists, both at home and abroad, who are recog- 

 niz.ed as collaborators in the classification of the collections. Some 

 of the more important results were as follows : Dr. H. J. Hansen, of 

 Copenhagen, Denmark, completed his monograph of the Euphausi- 

 acea ; and Dr. Joseph A. Cushman, of the Boston Society of Natural 

 History, the fourth part of his monograph of the North Pacific 

 Foraminifera, including the Chilostomellidse, Globigerinidse and 

 Nummulitidse, the fifth part, embracing the Rotalidse, being also 

 nearly read3^ Dr. H. A. Pilsbry, of the Academy of Natural 

 Sciences of Philadelphia, has nearly finished his studies on the sessile 

 Cirripedia; Dr. Charles B. Wilson, of the State Normal School, 

 Westfield, Mass., submitted another of his monographs on the para- 

 sitic copepods, dealing with the family Lernseopodidse ; and Prof. 

 C. C. Nutting, of the State University of Iowa, completed the third 

 part of his monograph on hydroids. Prof. A. E. Verrill, of Yale 

 University, in his report on the starfishes of the Harriman Alaska 

 Expedition, recently published by the Smithsonian Institution, de- 

 scribed a small collection lent him by the Museum; Prof. Frank 

 Smith, of the University of Illinois, continued his study of earth- 

 worms, especially those from America and British East Africa ; Dr. 

 R. Koehler, of Lyon, France, has undertaken to report upon the large 

 collection of Philippine ophiurans obtained chiefly by the steamer 

 Albatross in 1907-1910; and Dr. N. A. Cobb, of the Department of 

 Agriculture, has taken up the study of a small collection of non- 

 parasitic nematodes.
