440 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



observations of Verrill and others, that nearly all the fishes 

 which are most prized for richness and delicacy of flavor 

 the shad, the salmon, the trout, the white-fish, and the Otse- 

 ii'0 Lake bass 'are those whose diet is to a great extent 

 crustacean. Hence Mr. Lintner infers that the Crustacea are 

 the best food upon which fishes can feed. lie concludes that 

 food for fish should be transplanted, and streams and ponds 

 stocked with insects, Crustacea, etc. ; for he infers, first, that 

 in any stream having the same character of water, the addi- 

 tion of a similar fauna and flora should fit it for an equal 

 abundance of trout ; and, second, that streams, ponds, and 

 lakes having a different character of water (as to current, 

 temperature, substances in solution, etc.), by the addition of 

 a similar fauna and flora, may be fitted for an equal abun- 

 dance perhaps greater of some species offish desirable for 

 food. It is shown by the writer that insects and Crustacea 

 can be readily transplanted, and made to multiply in profu- 

 sion. In this connection he states that the craw-fish (Asta- 

 cus), under liberal appropriations made by the government, 

 is at the present time extensively cultivated in the rivers 

 and brooks of France for table use. 



Henry Woodward's catalogue of British fossil Crustacea, 

 just published by the British Museum, contains a record of 

 197 genera and 1051 species and varieties, or more than three 

 times as manv as were known in 1854. Of these, more than 

 300 are of trilobites, the largest of them (the JParadoxides 

 Davidis) being nearly two feet long. The Ostraeoda are 

 most numerous, amounting to more than 450. These are 

 largely represented throughout the entire series of fossil ifer- 

 ous formations, and are equally well represented among liv- 

 ing animals. Some important beds are chiefly composed of 

 these accumulated valves. 



The oldest short-tailed crab has recently been described 

 by Dr. Woodward, under the name of Brachypyge carbonis. 

 Before the discovery of this crab, the oldest one known was 

 from the great Oolite; the present species is from the car- 

 boniferous formation of Belgium. 



A fossil decapod crustacean (Anthracopalwmon IUllia- 

 num), represented by a carapace, is the first of this order 

 found in the coal formation of Nova Scotia. 



A fossil nebaliad crustacean and a species of Ih'mes, or
