Engraulis perfasciatus Poey, Meraorias, II, 1860, 313 (Cuba), 



Stolephorus perfasciatus, Jordan & Evermann, Fishes of North America, 441. 



23. Stolephorus brownii (Ginelin). Anchovy Fry. 



Atherina brownii Gmelin, Syst. Nat., 1397, 1788 (Jamaica). 



Stolephorus b>ownii, Jordan & Evermann, Fishes of North America, 443. 



24. Stolephorus robertsi Jordan & Rutter, new species. 



Head 3 in length ; depth 4 ; dorsal 14 ; anal 23 ; scales about 35 ; 

 eye 4 in head ; pectoral 2i ; base of anal If ; caudal 1}. 



Body deep, strongly compressed, abdomen compressed to an edge. 

 Head large, compressed, the snout rather sharp, projecting beyond 

 lower jaw, a little shorter than eye ; cheek triangular ; opercle large ; 

 distance from lower angle of cheek to edge of opercle equal to dis- 

 tance from same point to posterior edge of eye ; maxillary short, not 

 reaching root of mandible, its end rounded ; lower jaw not reaching 

 beyond anterior edge of orbit ; gill-rakers longer than eye, as long 

 as orbit; origin of dorsal midway between base of caudal and front 

 of eye ; scales caducous. 



Color translucent ; head silvery, punctulate above ; a silvery 

 lateral band nearly as broad as eye ; caudal with dark points, other 

 fins colorless. 



This species seems to be related to Stolephorus opercularis, but the 

 lateral band is distinct and the opercle is shorter. 



One specimen in the collection about 2 inches in length, No. 

 4,853, L. S. Jr. Univ. Mus.

 eye 3 i in head ; pectoral 1| ; base of anal 1|. 



Body rather elongate, not greatly compressed ; edge of belly 

 moderately sharp. Head sharp ; snout projecting beyond lower 

 jaw, shorter than diameter of eye ; tip of lower jaw reaching a little 

 past anterior edge of orbit ; maxillary reaching gill opening, its end 

 tapering to a sharp point ; eye longer than snout, nearly 2 in post- 

 orbital part of head ; gill-rakers two-thirds eye ; a slight keel on top 

 of head. 



Origin of dorsal midway between base of caudal and eye ; scales 

 caducous. 



Translucent, head silvery ; sides without lateral band, a dark spot 

 on top of head, back with black points.
