In the Proceedings of the Royal Society of Victoria (1909), 

 Miss Ethel E. Morris and Miss Janet Raff discuss the structure 

 of the little lancelet of the coast of Victoria, which they call 

 Asymmctrou bassanum. The generic name E piganichthys of 

 Peters has priority. 



In the Journal of the Royal Society of New South Wales, Vol. 

 XLI, Mr. H. C. Dannevig, of the Department of Fisheries, dis- 

 cusses the effects of the coastal winds of Australia on the abun- 

 dance of fish in inshore waters. He shows that the relative 

 abundance of many species in different places is due to the nature 

 of the winds. 



In the Annals of the Carnegie Museum, Volume V, Dr. Charles 

 R. Eastman describes a new fossil shark, Helodus comptus, from 

 Meadville, Pa. 



In the Aniui/s and Magazine of Natural History, Series 8, 

 Vol. 4, Mr. C. Tate Regan describes a number of new species of 

 fishes, mostly eels, from the South Seas and Australia. 



In the same journal, Mr. Regan discusses the three-spined 

 sticklebacks of the world. He finds those of the Atlantic coasts 

 of Europe and America and those of the Pacific coast alike, 

 including all the species of three-spined sticklebacks hitherto 

 described under the name of Gastrosteus aculeatus, with the 

 exception of G. algeriensis, which has a smaller number of ver- 

 tebra?, 29 instead of 31 to 33. He also describes a species with a 

 slender snout, from Rome, under the name of Gastrosteus holo- 

 gytnnus, and a new species, Gastrosteus santa-annic, from the 

 Santa Ana River in California. This he regards as distinct from 

 the naked specimens of Gastn>sl> u.< hitherto known as G. wilham- 

 soni, by the presence of 29 instead of 32 vertebra. The specific 

 distinction of G. santa-annn is very doubtful, but Mr. Regan is 

 doubtless correct in saying that mailed, half-mailed and naked 

 forms in Europe and America are the same species, those living 

 in the sea being fully mailed, those living in fresh water mostly 



In the same Annals, Mr. Regan discusses the caudal fin of 

 Elops and of other fishes. He finds the tail of Flops distinctly 

 heterocercal, like that of some of the fossil forms of earlier 

 periods. He also shows that the tail of Fit 

 cereal. In its general structure, it is like that of related i 

 but the caudal fin has disappeared.
