14. — DIGEST OF THE APPENDICES WHICII ACCOMPANY THIS REPORT. 



The appendices which acconipauy this report consist of thirty-two 

 papers, all of which have a more or less direct bearing upon the work 

 of the Fish Commission. A large proportion, moreover, relate to the 

 work accomplished at the stations of the Commission and by the vessels 

 in its service during the current year. Several of the longer papers 

 will be published iu pamphlet form for separate distribution. The ar- 

 rangement of the appendices is as follows : 



A. — The Fisheries. 



This appendix consists of a comprehensive report by the Commis- 

 sioner, Prof. Spencer F. Baird, upon the Sea Fisheries of Eastern North 

 America. The paper was mostly prepared in 1877 and 1878, but was 

 withheld from year to year for revision and completion, until it became 

 evident that the author's declining health would prevent his giving the 

 subject further attention. It is an important contribution to the liter- 

 ature of the American fisheries, and shows much careful research and 

 thoughtful study. 



B. — Scientific Investigation. 



Four papers are included in this appendix, two relating to fishes and 

 two to marine invertebrates. The first is by Prof. D. S. Jordan and Mr. 

 D. K. Goss, his assistant, upon the flounders and soles of America and 

 Europe; the second is by Professor Jordan and Mr. C. H. Eigeninann, 

 upon the Sciamidae (drum-fishes, etc.), of the same region. The former 

 is illustrated by 23 figures the latter by 12 figures. Prof. Edwin Linton 

 reports upon the Entozoa, or intestinal worms of the marine fishes of 

 New England, and Mr. J. Walter Fewkes, upon the medusae collected 

 by the steamer Albatross during its cruise to the Gulf Stream in the 

 winter of 1885-'86.
