groups, and of others in which the facts obtained from a study of 
the recent crinoids are applied toward the solution 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- 
nized 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 Chilostomellid, Globigerinide and 
Nummulitide, the fifth part, embracing the Rotalide, being also 
nearly ready. 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 Lernzopodide; 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.
