﻿54 HOLBROOK, FISHES OF FLORIDA, GEORGIA, &c. 



tremity of the upper jaw reaching to the middle of the orbit; the lower jaw is the 

 the larger, and makes part of the facial outline when the mouth is closed- The lower 

 jaw and the intermaxillary bones are armed with small, pointed, closely set teeth, re- 

 curved and placed in a broad group with an outer row of larger, conical, and pointed 

 teeth. The vomer is furnished with a small, arrow-headed patch of very minute 

 teeth, and the palate bones with a narrow band of similar teeth. The tongue is broad, 

 and armed with a patch of similar teeth or asperities. 



The dorsal fin is long, but not much elevated ; it has ten spines, the anterior short, 

 the sixth and seventh longest, and ten branched rays longer than the spines. The 

 pectoral is rather broad ; it begins just at the back of the opercle and terminates at 

 the root of the second anal spine, and has fourteen rays. The ventral arises nearly 

 with the pectoral, and ends rather behind the vent ; it has one stout spine and five 

 soft rays. The anal arises opposite the root of the ninth dorsal fin and terminates in 

 a rounded extremity with it behind; it has three spines, the anterior short, the others 

 long and stout, and ten branched rays. The caudal is large, broad, slightly notched 

 behind, and has seventeen rays. 



The scales are large, quadrilateral, straight and broadest before, rounded and ciliated 

 behind. The lateral line runs parallel with the dorsal arch to the extremity of the 

 dorsal fin, whence it descends to the median plane. 



Color. See Specific Characters. 



Dimensions. The distance from the opercle to the tip of the tail is equal to two 

 heads and a half; the greatest elevation without the dorsal fin, is equal to one head 

 and one eighth ; total length, ten inches. 



Geographical Distribution. St. John's river, Florida. 



General Remarks. This fish, though it bears a close resemblance to the Calliurus 

 rnaculatus of Eafinesque, may be distinguished from it by the breadth of the bands 

 of its vomerine and palatine teeth ; by the larger scales, and by the lesser thickness 

 of its body in front of the dorsal fin. Specimen in the collection of Prof. Agassiz. 



Genus PIMELODUS, Ouvier. 



Pimelodus marmoratus.
