The same zoologist has also described eleven species of Cy- 

 prinodontidae, Cyprinidae and Catostomidae from the various parts 

 of North America. 



On the Atlantic coast the labors of the Fish Commission have 

 added several new species to our fauna. Professor G. B. Goode 

 (Proc. U. S. Nat. Museum, Nov., 1880) describes seven new spe- 

 cies of fishes that were the result of a single day's work of the 

 Fish-hawk at the edge of the Gulf Stream in Southern New Eng- 

 land. In this one day 120 species of invertebrates and fishes 

 were added to the fauna of the region south of Cape Cod. The 

 two new Pleuronectidae are ranged under as many new genera, and 

 the genus Hypsiconetes is instituted for a species which is appa- 

 rently gadoid, but in some respects resembles the blennioids. 

 The same naturalist contributes to the Bulletin of the U. S. Fish 

 Commission, 1 881, an account of the habits, range and economic 

 values of the carangoid fishes, pompanoes, crevalles, amber fish, 

 etc., of the Atlantic coast; and also a digest of the recent litera- 

 ture upon the life-history of the eel. There appears to be but 

 little doubt that the organs of Syrski are the testes, but no one 

 has as yet observed the spermatozoa in the common eel. Mr. 

 Goode, however, has omitted any reference to a paper in this 

 journal (Vol. xnr, May, 1879, P- 3*9) b >* Professor A. S. Packard, 

 Jr., and J. S. Kingsley, who were the first to discover the male eel 

 in America, three specimensjiaving been obtained at Wood's 

 Holl, while Mr. Kingsley claims to have seen the spermatozoa. 



Dr. Theodore Gill, in his review of Dr. Gunther's Introduction 

 to the study of Fishes, severely criticises the latter's definition 0/ 

 a fish, and also the bibliography. The treatise is valuable from 

 the thorough acquaintance with both external and internal char- 

 acters which it displays. 



Dr. Franz Steindachner { Ichthyologische Beitrage ix, Sitz. kais. 

 Akad. Wiss., Wien, July, 1880), describes two species of Agonus 

 from California, which have been shown to be identical with two 

 species of Brachyopsis (Agonus pars) described a short time be- 

 fore by Lockington and Jordan respectively. The description is 

 accompanied by figures. In No. xi of the same series (188 1 ), 

 Dr. Steindachner describes Trichodon japonicus, which ranges 

 from Japan to Sitka. 



Mr. Henry J. Rice (Amer. Nat., Jan., 1880) contributes a valu- 

 able article upon tbe habits, structure and development of Am-
