Head 3; long dorsal rays 2 ; pectoral 2f ; long anal rays 2^ ; depth li, 

 the young much deeper. D. VII -I, 23;* A. II-I, 18. Anterior prolile from 

 tip of snout to occiput almost perfectly straight in the adult. Diameter 

 of eye, length of opercle, and distance from eye to profile about equal ; 

 eye 2 in maxillary, 21 in preorbital ; mandibles very deep, the dentary 

 bones thin, approximate ; one or two of the dorsal spines greatly elongate 

 and filamentous in the young, short in the adult ; ventrals variable in 

 length, usually about as long as the eye in the adult, variously elongate 

 in partly grown specimens. Color uniform silvery iu the adult. Our 

 observations of this species tend to confirm the correctness of Dr. Lutken's 

 views (Spolia Atlantica, 139) as to the transformations incident to its 

 growth. Tropical America, on both coasts, from Capo Cod to Brazil, and 

 from Lower California to Peru. Very common southward on sandy 

 shores, both iu the Atlantic and Pacific. The Pacific Coast form, hre- 

 %-oortn::^pacificu!i, is not evidently diiferent from Sdeue vomer. {vomer, 

 a plowshare.)
