in some cases. Height of anal 12 in head. Caudal deeply concave, 
length 12 in head. Pectorals broad, rather pointed posteriorly, 
2in head. Ventrals rounded, 12 in head; origin of fin below seventh

Lateral line straight except for a slight upward curve at its origin. 
Scales small anteriorly, growing gradually larger posteriorly, minute 
on breast and abdomen; 15 in a series, counting upward and forward 
from lateral line to a point midway between occiput and dorsal, about 
12 between lateral line and base of dorsal, 13 between lateral line and 
insertion of ventral. 
Color in spirits dusky above, lighter below; each longitudinal row 
of scales with a conspicuous light stripe which is equal to about one-

Described from the type, Cat. No. 61675, U.S.N.M., a specimen 153
