bluntish and equal, pectorals long, ventrals short. Dark olive brown, 

 gradually paler below, young with pale streaks along the rows of scales ; 

 a faint dark spot above pectoral ; tips of dorsal and caudal more or less 

 dusky. Head 4| ; depth 5| to 6. D. 11 ; A. 8. L. 12 inches. Rivers of 

 Carolina and Georgia from the Catawba to the Chattahoochee ; abundant 

 about rocks and rapids, representing the next species from the Catawba 

 southward, (rupiscartes, rupis, rock ; aicapTw, jumper, a word used by 

 Swaiuson for a blenny which jumps on rocks like a lizard.)

323. MOXOSTOMA CERVINUM, (Cope). 



(JUMPING MULLET.) 



Head very short, roundish above, rather pointed forward, about 5 in 

 length. Cheeks subvertical, their depth less than I the distance from 

 snout to preopercle. Mouth rather large, with thick lips, which are 

 strongly plicate, the folds somewhat broken up. Eye small. Fins very 

 small; the dorsal rays 10 to 12; free edge of 'dorsal straight, its longest 

 ray less than head. Scales rather large, 6-43-5, 13 before dorsal. Color 

 greenish brown ; a pale blotch on each scale, these forming continuous 

 streaks along the rows of scales, back with more or less distinct brownish 

 cross blotches; fins brownish, not much red, the dorsal and caudal inky 

 black at tip. Size smallest in the genus, length 8 to 10 inches. Rivers 

 of the South Atlantic States from the James to the Neuse, abundant in 

 rapids and pools among rocks, (cervinus, fawn color.)

98. PLACOPHARYNX, Cope. 



Placopharynx, COPE, Proc. Am. Phil. Soc. Phila., 1870, 467, (carinatus). 



Suckers like Moxostoma in all respects, except that the pharyngeal 

 bones are much more developed and the teeth reduced in number, those 

 011 the lower half of the bone very large, 6 to 10 in number, nearly cylin- 

 dric in form, being but little compressed and with a broad, rounded, or 

 flattened grinding surface.* Mouth larger and more oblique than usual 

 in Moxostoma, the lips thicker. Size large. (7r/ld, a broad surface ; 

 pharynx.) 



* The forms and position of these enlarged teeth vary considerably ; in a specimen before us 

 tli- first tooth is the highest and most compressed, its summit being rounded and then abruptly 

 truncate ; the second tooth is notably shorter and thicker, much larger, and rounded on top, the 

 body of the tooth serving as a peduncle for the swollen grinding surface ; the third tooth is still 

 shorter and similar in form ; the fourth tooth is similar to the first, being much higher than the 

 second and third, and flat on top ; the others seem to be irregularly alternated or arranged in 

 pairs, a long one and a short one, the long teeth in all cases being the moat truncated, as if 

 their surfaces had been most worn off.
