of the ship — were let down after dark, one of the nets containing the 

 incandescent lamp. It was found that in the illuminated net there was 

 an abundant gathering of crustaceans, while in the dark net there was 

 practically nothing. 



In connection with the work carried on at the Puffin Island Biological 

 Station, Mr Isaac C. Thompson has very completely investigated the 

 copepoda, and has published several papers in the Proceedings of the 

 Liverpool Biological Society on this group of organisms. Mr Thompson's 

 observations have resulted in adding a number of species new to Britain 

 and new to science, — the most remarkable addition being probably 

 Cymbasoma lip.rdmani, a previously described species of this genus, 

 C. rigid am, discovered by Mr Thompson at Tenerift'e, having necessitated 

 the constitution of a new family for its reception, the Cymbasomatida?. 

 Mr Thompson, in a report on the copepoda of the Maltese Seas,* has 

 described 68 species, 3 of which are new to science. 



Dr Day, after an interval of ten years since the publication of his 

 1 Fishes of India,' now issues a supplement! to that great work, so as to 

 make it as complete as possible. Many new forms have been obtained 

 from the seas and inland waters of India, and these Dr Day has described 

 in a supplement of about 40 pages, which includes a very full index to 

 the genera and species described. Dr Day adds to his former work the 

 sub-class Leptocardii, and notes that one or more species of Amphioxm 

 are common to India, Burmah, Ceylon, and the Andaman Islands. By 

 this work Dr Day makes all interested in pisciculture more than ever 

 indebted to his patient and painstaking researches. 



THE UNITED STATES. 



The Report of the United States Fish Commissioner for 1886 has not 

 yet come to hand ; but we have received four volumes, in continuation of 

 those previously published, on the Fishery Industries of the United 

 States. This elaborate work has been prepared by Professor Brown 

 Goode, assistant secretary of the Smithsonian Institution, and a staff of 

 associates, through the co-operation of the Commissioner of Fisheries. 

 Sections III. and IV. are published in the same volume. Section III. 

 contains a most extensive and elaborate account of the Fishing Grounds of 

 North America, — the location, character and the productiveness of the 

 numerous grounds resorted to by the fishermen of the United States 

 being described. These extend from Greenland to Mexico, from Lower 

 California to Alaska. The text is illustrated by 49 charts, showing the 

 position of the grounds, depth of water, &c. ; and is accompanied by an 

 appendix on the ocean temperatures of the eastern coast of the United 

 States, with 32 graphic charts. This section contains also an account by 

 Dr S. Jordan of the geographical distribution of fresh-water food fishes 

 in the several hydrographic basins of the United States. Section IV. 

 deals with ' The Fishermen of the United States,' and is profusely illus- 

 trated. The men engaged in the various fisheries, at different parts of 

 the coast, their life, &c. are described, an account being, as a rule, given of 

 their economic and social condition. There are also chapters on the 

 dangers of the fisheries and on the management of the vessels. 



Section V., which is published in tw T o volumes, deals with the History 

 and Methods of the Fisheries, and is illustrated by an atlas of 255 plates. 

 Each of the fisheries is described with a wealth of details not often found 

 in fishery works published in this country, — for instance, 119 pages are
