The Proc. U. S. Nat. Mus. for 1 88 1, contains descriptions of 

 forty new species from Mazatlan, thirty from Panama and a few 

 others from the Gulf coast, all by the same hard-working ich- 

 thyologists. 



In the same volume Mr. C. L. Mackay reviews the genera and 

 species of Centrarchidse, and describes a new species of 

 Lepomis. 



W. N. Lockington (Proc. U. S. Nat. Mus., 1880) describes ten 

 new species of fishes from various parts of the Pacific coast, the 

 most noticeable of which are Prionotus stephanophrys, taken near 

 San Francisco ; Myriokpis zonifa-, a singular Chiroid, and the curi* 

 ous soft-boned Tc <steus tznigm itiats, for the reception of which and 

 his own Icich rofessor Jordan subsequently insti- 



tuted the family Icosteidae. In the long low dorsal and anal, as 

 well as in the extreme flexibility of the skeleton, these species agree, 

 but while Icosteus is scaleless, with groups of spinules along the 

 lateral line and spinules upon the fins, Icicthys is entirely scaly 

 and without spinules. 



The same writer (Proc. Phil. Acad. Nat. Sci.) describes some 

 new species from the Gulf of California, and a Catostomus from 

 the Gila. 



Miss Rosa Smith describes a Cremnobates and a Gobiesox from 

 Southern California. 



Dr. T. H. Bean (Proc. U. S. Nat. Mus., 1880) describes a new 

 hake from South Carolina, and in the same volume S. Garman 

 gives a synopsis of the American Rhinobatidae, and Professor Jor- 

 dan notices a new Caranx from S. Carolina. 



S. Th. Cattie, of Arnheim, Holland, also contributes some in- 

 formation respecting the structure of the organ of Syrski in the 

 male eel, and the external characters of the sexes in that fish ; 

 and Professor O. P. Hay describes fifteen new species from the 

 eastern part of the State of Mississippi, from affluents of the 

 Mississippi and Tombigbee, and from the Chickasawha. Eight 

 of these specie- im hid ng th n _ < n is Opsopueodus) are Cyp- 

 rinidoe, the remaining seven Etheostomatidae. 



The U. S. Coast Survey Steamer Yukon proceeded, in 1880, 

 along the coast of Alaska, calling at various points to make col- 

 lections. The expedition was accompanied by Dr. W. H. Dall 

 and Dr. Tarleton H. Bean, the latter of whom made a valuable 

 collection of fishes, of which he gives a preliminary description
