REPORT OF COMMISSIONER OF FISH AND FISHERIES. IX 



to the vessels, boats, and apparatus employed, and the methods of catch- 

 ing and preserving fish. Another important investigation covered by 

 this report is that of the southern mackerel fishing grounds in the 

 spring of 1888. Incidental to this was the inquiry concerning the 

 pound-net fisheries of Chesapeake Bay. The report is accompanied by 

 numerous temperature records, and is illustrated by 1G plates. 



Scientific investigations made on behalf of the Commission by Dr. 

 David Starr Jordan, president of the University of Indiana, Prof. S. A. 

 Forbes, director of the Illinois State Laboratory of Natural History, 

 and Prof. Edwin Linton, of the Washington and Jefferson College, 

 Washington, Pennsylvania, are made the basis of special reports by 

 these authors. Dr. Jordan's contribution is a review of the Labroid 

 fishes of America and Europe, in which he gives a systematic catalogue 

 of all the species of this family of fishes (old wives, wrasses, doncel- 

 las, pudianos, parrot fishes, dinner, and tail tog) found in the waters of 

 America and Europe, with the synonymy of each species and analytical 

 keys by which the various genera and species may be distinguished. 

 This important monograph is accompanied by eleven plates, showing 

 twelve of the one hundred and fifteen species discussed. 



The article by Professor Forbes on " Some Lake Superior Entomos- 

 traca," is a valuable contribution to our knowledge of the crusta- 

 ceans of Lake Superior. It has an important economic relation to some 

 difficult problems of fish-culture in the Great Lake region, since the mi- 

 nute crustaceans treated by Professor Forbes constitute the principal 

 supply of food for the young of several valuable edible species. The 

 paper contains descriptions of several new species and two new vari- 

 eties of Eutomostraca, and is illustrated by four plates. 



The notes on the Entozoa of marine fishes of New England, with 

 description of several new species, is the second part of a series of pa- 

 pers by Prof. Edwin Linton, of the Washington and Jefferson College, 

 Washington, Pennsylvania. It comprises 149 pages of text and 15 

 plates, and relates to forty-two species of Cestod worms, of which 

 twenty-seven are described as new to science, eight of these represent- 

 ing new genera. 



These parasites were found in a variety of fishes, but principally in 

 the sharks and rays. This is one of the most important contributions 

 to the subject of fish parasites which has been given to the public.
