We may notice the eye well advanced. It further differs in the den- 

 tition and by the extreme division of its pyloric appendages. The teeth 

 are in a large band, a little narrower in the lower jaw ; the external 

 margin shows a row of teeth a little stronger, especially the two first, 

 but there are no differentiated canines ; the extreme inner series in front 

 has some stronger teeth. The palatine and vomerine teeth are in finer 

 bands. The cceca and their divisions are innumerable." {Poey.) Else- 

 where the cranium is described as short, broad, and flat, the occipital 

 crest very low. Size enormous, as in the genus Stereolepis. This genus 

 and Trisotro'pis should probably be considered as sections of JEpinepJie- 

 lus. {-po, before ; /j.r/.poq, small ; wv, eye ; in allusion to the shortness of 

 the anterior part of the cranium, due to the advancement of the orbit.;

 pressed above than below. Mouth large, maxillary reaching beyond 

 the orbit; preopercle feebly serrated ; opercle with 3 flat points; fins 

 all very low, caudal rounded. Head 3^; depth 4. D. XI, 16; A. Ill,

 (Cnvier, R^gne Anim. ed. 2d, ii, 1829: type Dules auriga C. & V.) 



Body oblong, ovate, compressed and elevated, covered with rather 

 large scales. Mouth large, the lower jaw projecting ; the maxillary 

 reaching to opposite the middle of the eye. Teeth moderate, the ante- 

 rior in the upper jaw enlarged, wide-set, but hardly forming canines. 

 Preopercle sharply serrate; opercle with 2 strong spines. Dorsal 

 with 10 spines, anal with 3; the third dorsal spine filamentous, the 

 second anal spine longest. Branchiostegals 6. Fishes of the warm 

 seas, sometimes entering rivers. (t?oD;.o<r, a slave ; the fish being under 

 the lash of the long dorsal spine.)

Yellowish gray, with two or three darker cross-bands and faint dark 

 longitudinal streaks. Opercle with two or three strong spines, the upper 

 one the largest; pectoral and ventral fins large; third dorsal spine fila- 

 mentous, reaching the middle of the caudal; caudal truncate. D. X,

 said to have been taken on our coast.
