23. Cynoscion magdalenae (Steindachner) Jor. & Gilb. 

 Common in the bay of San Diego. 



24. Menticirrus elongatus (Gunther) Gill. 



A large species of Menticirrus, probably Umhrina elongata of Giinther, 

 is taken occasionally in the bay. We have obtained one specimen. 



25. Corvina saturua (Girard) Steindacliuer. 

 Not uncommon. 



26. Roncador stearnsi (Steindacliner) Jor. & Gilb. (gen. nov.). 



Common. This species, having a serrated preopercle and only villiform 

 teeth in either jaw, is not a Corvina as that genus is understood by many 

 recent writers. Its relations are rather with Scicenops ocellatus, with which 

 it is, however, hardly congeneric. We propose to consider it as the type 

 of a distinct genus or subgenus, for which the name Roncador, applied 

 to it by the Italian fishermen, may be adopted. This word appears also 

 in the Latin name of a related species, Umhrina ronchus. 



Roncador, gen. nov. Allied to Corvina and Scicenops. 



Body moderately elongated, the head deep, the profile declivous, lower 

 jaw included; both jaws with a broad band of villiform teeth only; no 

 enlarged teeth or canines ; pseudobranchite present ; i)reopercle strongly 

 and evenly dentate posteriorly, entire below ; spines strong, the second 

 of the anal very robust, but not very long ; caudal fin lunate, air-blad- 

 der large. 



This species, Roncador stearnsi, is as readily distinguished by the black 

 pectoral spot as its relative, Scicenops ocellatus, is by the black spot on 

 the caudal.
