larvse; and for the taoging of sciip. With the collaboration of the 

 fish-cultural staff, some 4,000 flounders caught incidental to hatchery- 

 operations were tagged at the station ; also more than 300 brood cod. 



Due to the limited funds available for station maintenance, the 

 buildings and equipment have not kept pace with the requirements 

 of the bureau's program. Particularly urgent is the replacement of 

 the collecting vessel and the station launches with more seaworthy 

 craft capable of operating appropriate fishing gear. The station's 

 usefulness would also be greatly increased by weatherproofing the 

 buildings, to permit occupancy for experimental work during the 

 winter and early spring periods, which is the only time that early 

 life-history material on certain important food fishes is available. 



In accordance with the bureau's long-established policy of encour- 

 aging independent research in marine biology and related subjects, 

 the facilities of the laboratories at Woods Hole, Mass., were made 

 available to a number of investigators from various educational in- 

 stitutions. Personnel so accommodated at Woods Hole included: 

 Dr. Kobert P. Bigelow, Massachusetts Institute of Technology, sto- 

 matopoda of the Albatross Philippine expedition; Frank A. Brown, 

 Harvard University, mechanism of color changes in the shrimp; 

 Dr. N. A. Cobb and assistants, Department of Agriculture, nematodes ; 

 Paul S. Conger, United States National Museum, diatoms of the 

 Woods Hole region; Kendall W. Foster, Harvard University, color 

 changes of Fundulus ; Dr. F. G. Hall. Duke University, respiration of 

 fishes; Charles W. Hooker, Duke University, respiration of fishes; 

 Mrs. Helen W. Imlah, Radcliffe College, effect of thyroxin on the 

 ascidian larvae; Dr. George B. Jenkins, George Washington Univer- 

 sity, vertebrate embryology; Dr. Edwin Linton, University of Penn- 

 sylvania, helminth parasites of fishes; W. G. Lynn, Johns Hopkins 

 University, embryology of the nervous system of reptiles; Dr. J. H. 

 Sandground, Harvard University, helminth parasites of fishes; G. W. 

 Taylor, Princeton University, respiration of luminous bacteria and 

 permeability in starfish eggs; Sam R. Tipton, Duke University, res- 

 piration of fishes; Dr. C. B. Wilson, State Normal School, West- 

 field, Mass., copepods of the Carnegie expedition. 



BEAUFORT, N. C. 



Research. — The Beaufort laboratory under the direction of Dr. 

 S. F. Hildebrand until July 1, 1931, and under Dr. Herbert F, 

 Prytherch after that date, is being developed as a research center 

 in the South Atlantic region for marine studies in both pure and 

 applied biology. The chief investigations conducted here at present 

 by the bureau's staff, as reported elsewhere, deal with the biology 

 and cultivation of the oyster, the copper content of inshore coastal 

 waters, the development and distribution of the shrimp, and the 

 propagation of the diamond-back terrapin. Laboratory facilities 

 have been furnished to independent research workers from other in- 

 stitutions who have engaged in the following studies: Dr. H. V. 

 Wilson and Joseph H. Pratt, jr., of the University of North Caro- 

 lina, cellular behavior in the embryonic development of hydroids 

 (Pennaria), the early development of sea urchins (Toxopneustes), 

 and the regeneration of young ascidians (Styela) ; Dr. Bernard
