tapper jaw longer, longer than the head, one sixth of total 

 length, flat and narrow: body cylindrical olivaceous brown a- 

 bove, white beneath: dorsal fin with eight rays, anal fm with 

 ten, abdominal with six, lanceolate acute, spotted with black; 

 lateral line straight, but raised upwards at the base. 



This is a Very distinct species by the shape of the jaws and 

 tail. It is found in the Ohio; but is by no means common. It 

 Teaches six feet in length. Its flesh is not very good to eat, ra« 

 ther toagh and strong smelling, like that of some strong stur- 

 geons. The individual which I observed was caught at the fallsj 

 and was SO inches in length, with the upper jaw 5 inches long, 

 •while the lower jaw was only four inches: the upper one has 

 three furrows and juts over the lower by a thick curved obtuse 

 point with four small openings or nostrils, although there were 

 two other cblcng nostrils in obliciual furrows, at the base before 

 the eyes. This does not appear in L.jilatosiomus. Lower javr 

 straight with a membrane between the lateral lines. Teeth 

 unequal straight very sharp and on a single row. Breadth of 

 the jaws one eighth of t4ie length. Iris large and gilt. Head 

 rough nearly square, covered with six broad plates, two of 

 which on each side, and of a fulvous grey colour. Body cylin- 

 <?rlcal covered vviih the usual hard scales in oblique rows; but 

 r.ct two bcales exactly alike either in shape or size; they are 

 generally elongated obliquely with the two longest lateral sides 

 straight, the upper one concave and the lower one convex, but 

 these is a row of obccrdated ones on the back. All the fins 

 fulvous, the pectoral lanceolate acute with 12 rays, the abdom- 

 inal lanceolate acute and with only S rays. Dorsal and anal 

 trapezoidal elongated, serrated by scaly rays anteriorly. Cau- 

 dal fins with 12 rays, one sixth oi total length, covered with a 

 few large black spots, df a lanceolate shape, with an oblique 

 jRcxuose fease decurrent beneath Bnd acute at the end, serrated 

 toth upwards and downy, arda and serratures extending on the 

 boay. Lu.'oral line not obsolete, quite straight, but raised a lit- 

 tle upwards* ,.t the base.
