much uarrower, and the color of body and fins is much darker; tlie 

 preopercnlar denticuhitions are stronger, the snout longer and the eye 

 smaller. It is possible that the soutliern form may represent a tangible 

 variety, but our material is not sufficient to enable us to characterize it. 

 The Charleston specimens showed in life the following coloration ; 

 The basal half of eacli scale dark brown, the terminal half silvery, with 

 bluish tinge; snout and lower jaw dark chocolate-brown, the end of the 

 snout and the tip of lower jaw white; sides of head with brassy luster, 

 and marked with about 18 very narrow, often wavy, blue lines, the 

 widest on the snout being less than half width of interorbital space ; 

 a few of these lines are extended on the body for a very short dist- 

 ance (less than diameter of eye) ; two or three stripes run concentrically 

 around snout above, joining anterior margins of orbits ; mouth very bright 

 scarlet. A dark brown bar across base of pectoral, continued half way 

 down on axil; fins brownish olive ; ventrals and anal blackish, the ven- 

 trals margined externally with white. Scales below pectorals with 

 numerous very short and narrow, horizontal, black lines ; scales on 

 lower part of sides, and above lateral line, with dendritical clusters of 

 dark lines diverging from the base. No blue streaks on low^r part of 

 sides. 



73. Lobotes surinamensis (Bloch) Cnv.— Black Perch; AV« Perch. 



Occasionally taken ; a single specimen seen during the summer. 



74. Calamus bajonado (Bloch iS: Schneider) Poey. White-hone Porgy, 



A well-known food-fish at Charleston, averaging much larger than 

 the common Porgy, specimens 18 inches long being of not infrequent 

 occurrence. 



Our specimens fail in many respects to answer the incomplete de- 

 scription given by Poey (Monogr. des Sparini, 176), notably in the num- 

 ber of canines in each jaw (8 instead of 0) ; but this is in all probability 

 the species described by him. 



Head 3^ in length ; depth '2\ ; pectoral .3 ; snout two-thirds head ; 

 eye two-ninths ; maxillary three-sevenths, and ventral five-eighths head. 

 D. XII, 12 ; A. Ill, 10. Pores in lateral line 44. 



The young (5 inches long) is olivaceous, with white longitudinal lines 

 above and on sides, formed by series of spots, one on each scale ; sides 

 of body with many irregular narrow dusky blotches, with a tendency 

 to form bars on lower half of sides ; belly whitish ; vertical fins and 

 ventrals with irregular wavy bars of dusky and whitish ; pectorals with 

 a dusky bar at base. Adults have all the markings less evident, with 

 usually no trace of vertical bars on sides; the dusky and whitish bands 

 on fins persisting. 



75. Steuotomus chrysops (Linn.) Bean.— /'orj/y. 



An abundant food-fish, usually not reaching a length of more than S 

 inches. The second ray of the dorsal is frequently filamentous. The
