fishes of Brazil, this volume treating of the sharks, with de- 

 scriptions of each species, and analytical keys. The memoir is 

 beautifully printed and illustrated by photographs of very many 

 of the species. The synonymy is given in an appendix, and the 

 nomenclature is in general in accord with the rules adopted by 

 American naturalists and by the International Congress. 



Dr. C. T. Regan continues the catalogue of the fishes of Cen- 

 tral America. Brycon guatemalensis is described as new from 

 Guatemala. Tetragonopterus macrophthalmus is described 

 from southern Mexico, as is also T. angustifrons. Mr. Regan 

 recognizes a number of additional species of Lepidosteus. It 

 is very desirable that the garpikes of the United States should 

 receive a critical review. It is quite possible that more species 

 really exist than the three which have been recognized by Jordan 

 and Evermann. Mr. Regan proposes the name Conorhynch- 

 ichthys in place of Conorhynchus, the latter name being pre- 

 occupied. This paper completes the study of the fishes in the 

 fauna of Central America. It is a very important and very well 

 executed piece of systematic work. 



In the Transactions of the Linnean Society of London, Mr. 

 Regan gives an elaborate account of the fishes collected by the 

 Percy Sladen Trust Expedition to the Indian Ocean in 190b, 

 under the leadership of Mr. J. Stanley Gardiner. One hundred 

 and eighty-five species were obtained, many of them new to 

 science, these being figured in the present volume. Among other 

 interesting forms are six new species of the genus Champsodon. 



Under the head of "Edible Fishes of New South Wales," Mr. 

 David G. Stead, naturalist of the Board of Fisheries at Sydney, 

 gives a popular account of the fishes which appear in the 

 markets of Sydney, illustrated by numerous photographs. This 

 interesting and valuable report is accompanied by a map of the 

 state of New South Wales. 



Under the title of "Trout Fishing in New South Wales," Mr. 

 Charles Thackeray, of Sydney, gives an account of the various 

 streams in the state, in which trout from Europe and the United 

 States have been introduced. The little volume is extremely 

 valuable to Australian anglers, and is also interesting as showing 

 the remarkable success which has attended the introduction of 

 the California rainbow trout in the Antipodes.
