were visited. Dr. Harriet Richardson, collaborator, continued her 

 studies on isopod crustaceans, naming such as were received during 

 the year, especially some collected by the Charcot expedition to the 

 Antarctic Ocean : and also preparing descriptions of a number of 

 single species from various localities. 



Sir John Murray, of Edinburgh, Scotland, while in Washington in 

 the spring of 1911, examined cursorily the entire collection of marine 

 deposits derived from the explorations of the steamers of the Bureau 

 of Fisheries and from other sources, and selected many samples which 

 were to be forwarded to him at Edinburgh for more detailed inves- 

 tigation. The bottom samples from the dredgings made by the 

 steamer Albatross in the north Pacific Ocean in 1906 were gone over 

 by Dr. Albert Mann, of the Department of Agriculture, for the pur- 

 pose of sorting out the diatoms, on which he will report to the Bureau 

 of Fisheries. Dr. Harold Heath, of Stanford University, examined 

 the alcoholic collections of alcyonarians and hydroids for specimens 

 of parasitic or,commensal solenogastrids which he is studying. Sat- 

 isfactory progress is to be noted in the working up of collections 

 belonging to this division by persons attached to other institutions. 

 Dr. J. A. Cushman, of the Boston Society of Natural History, com- 

 pleted the second part of his bulletin on the foraminifera (Textu- 

 lariidae) of the north Pacific Ocean, and has the third part (La- 

 genidae) well under way. Dr. Nelson Annandale, of the Indian 

 Museum, Calcutta, finished part 5 of the series of papers he is pre- 

 paring on the fresh-water sponges. Reports on the Cumacea by Dr. 

 W. T. Caiman, of the British Museum, and the Euphausiacea by 

 Dr. H. J. Hansen, of Copenhagen, Denmark, are nearly ready. Other 

 studies were being actively continued, as follows: On the starfishes of 

 the north Pacific Ocean by Dr. W. K. Fisher, of Stanford University ; 

 parasitic copepods by Dr. Charles B. Wilson, of the State Normal 

 School, Westfield, Massachusetts; New England bryozoa by Dr. R. C. 

 Osburn, of Columbia University; the Sipunculoidea by Dr. J. H. 

 Gerould, of Dartmouth College ; shrimps of the family Crangonidse 

 by Dr. H. Coutiere, of the University of Paris; certain Echinoidea 

 by Dr. Th. Mortensen, of the Zoological Museum, Copenhagen; 

 amphipod crustaceans from the Gulf of Mexico by Dr. A. S. Pearse, 

 of the University of Michigan ; hydroids by Prof. C. C. Nutting, of 

 the University of Iowa ; and medusae of the Pacific Ocean by Dr. 

 H. B. Bigelow, of the Museum of Comparative Zoology. Prof. J. W. 

 Spengel, of the University, Giessen, Germany, has undertaken the 

 study of the Echiuroidea, and Dr. C. Dwight Marsh, of the Depart- 

 ment of Agriculture, of the fresh-water copepods. 



The helminthological collections which constitute a section in the 

 division of marine invertebrates are, for the convenience of the 

 honorary custodians who have charge of them, partly kept and cared
