 large, thin, smooth, deciduous, 30 in lateral line. 



Body oblong, compressed, the forehead evenly rounded; lower jaw extending slightly beyond upper; 

 deptlt of caudal peduncle 3 in head, cental to diameter of eye: maxillary equal to postocular part of head, it- 

 distal end extending beyond eye a distance equal to one-half of orbit; mandible 1.7 in head; mouth oblique.
