DESCRIPTIOIV OF NEtV fSPKCIEJ^ OF NORTH AITIFKICAIV FISHES. 



By DAVID S. .lORDAN. 



1. BOLEOSOMA VEXILLARE, sp. IIOV. 



Allied to Boleosoma effulgens. Body rather short and stout ; candal 

 peduncle not contracted; head moderate, the muzzle somewhat de- 

 curved ; eye moderate ; gill membranes scarcely connected ; cheeks and 

 breast naked ; opercles scaly ) a naked strip in front of the dorsal fin ; 

 opercular spine moderately developed ; second dorsal very short and highy 

 higher than long ; pectorals and ventrals not reaching to anal. 



Coloration olivaceous, the sides with traces of vertical bars, probably 

 greenish in life ; male with the iirst dorsal, ventral, and anal black ; sec- 

 ond dorsal and caudal strongly barred with black and white in fine 

 pattern ; head black ; female not seen, but probably without black. 

 Lateral line complete. Scales very large, 4-35-6. 



Head 4 in length to base of caudal ; depth 4§ 



Fin rays. Dorsal VIlI-10; A. I., 7. 



Length of type 2^ inches. 



This species differs from its relatives in the larger scales and the much 

 shorter and higher second dorsal. (D. IX-13 in B. effulgens.) 



The type was taken in the Kap])ahannock River at Warrenton, Va., 

 by a correspondent of "Forest and Stream," and forwarded to me for 

 idenliflcation by the editor of that journal, Mr. Charles Hallock.
