26 BUI^LETIN OF THE BUREAU OF FISHERIES. 



subsequent disposition of these specimens fell to the lot of Dr. Sumner. The tempera- 

 ture and density determinations of August, 1907, were conducted by Mr. D. W. 

 Davis, the series of November, 1907, and of March and June, 1908, being carried out 

 by Dr. Sumner. The temperature records of August, 1909, for Nantucket Sound and 

 Crab Ledge were obtained by Dr. Osburn and Dr. Cole. The systematic shore collect- 

 ing already referred to was almost wholly in charge of the two last-named persons, each 

 supported by a number of assistants detailed from the laboratory, while a careful 

 examination of the fauna of certain brackish ponds of the region was undertaken by 

 Dr. E. D. Congdon. 



A really complete list of those who are entitled to rank as collaborators in the 

 work of the Survey or in the preparation of this report would include a larger number 

 of names than could well appear upon the title-page. Our indebtedness to Mr. Vinal 

 Edwards has already been expressed, and the ser\'ices of certain assistants have been 

 acknowledged in the discussion of various phases of the work. No inconsiderable credit 

 for such success as has attended our efforts must be given to the commanders of the 

 vessels employed during the dredging operations. Especial mention must be made of 

 the able services of Boatswain James A. Smith, United States Navy, and Lieut. Franklin 

 Swift, United States Navy, commanding in successive years the steamer Fish Hawk, 

 and those of Mr. Robert N. Veeder, commanding the Phalarope. 



A Hst has already been given of those who have aided in the determination of 

 species, and reference has been made to the fact that certain of these experts accom- 

 panied many of the dredging expeditions, or at least examined the material immedi- 

 ately after its arrival at the laboratory. Thus Messrs. Bigelow, Cushman, Hargitt, 

 and Moore, and Misses Rathbun and Richardson were each present at the Woods Hole 

 Laboratory during one or more of the seasons devoted to the Survey operations. 



Acknowledgment must here be made of the cordial cooperation and willing help of 

 the foregoing persons and a number of others throughout the preparation of this report. 

 Each portion of the annotated list, or "catalogue," has been referred to a specialist for the 

 revision of the nomenclature. In the main, the list given on page 19 might be repeated 

 with the following qualifications: To Dr. Dall has been referred the portion of our list 

 relating to the Jlollusca, with the exception of the nudibranchs and the Pyramidellidae, 

 concerning which Dr. F. M. MacFarland ° and Dr. Paul Bartsch, respectively, have 

 been consulted. To Miss Rathbun alone we have referred the manuscript relating to 

 the local decapods; to Prof. Hargitt alone that relating to the ccelenterates; and to 

 Dr. Holmes alone the list of amphipods. Certain specialists not hitherto named have 

 likewise been kind enough to criticize the classification and nomenclature in the case 

 of various groups not represented in the dredging collections. Those deserving mention 

 are: Dr. G. M. Allen and Dr. Lynds Jones (birds). Prof. G. N. Calkins (Protozoa, other 

 than Foraminifera), Prof. Edwin Linton (parasitic flat worms and round worms), Mr. 

 R. W. Sharpe (free living copepods). Dr. Leonhard Stejneger (reptiles). Dr. F. W. True 

 (mammals), Prof. C. B. Wilson (parasitic copepods). 



In the case of certain minor groups the authors of the report must themselves 

 assume responsibility for the nomenclature employed, this being based upon the best 

 published work available. Some discussion will be devoted to the subject of classi- 

 fication and nomenclature in the section dealing with the annotated list. 



" Dr. MacFarland has gone so far as to prepare for us a sy-nopsis of considerable length, including the Woods Hole nudibranchs.
