blotches on the lateral line and about half the width of a scale lower a 
second series of twice as many smaller and fainter ones. There are faint 
indications of transverse bands on the back, connecting with the larger 
blotches on younger individuals. Dorsal and caudal darker backward ; adi- 
pose fin with light edges; ventrals and anal yellowish white. On the older 
individuals the markings are obsolescent. 
Distinguished from S. Evermanni J. B., by the greater number of scales 
and the larger dorsal and anal, and from S. Jenkinsii J. B., by the smaller 
number of scales, the smaller anal, the coloration, ete.

This is one of the stoutest known species of the genus; it is compressed, 
being about three fifths as wide as deep, and tapers from nape and dorsal 
to snout and tail. The greatest depth is three sixteenths of the entire 
length. Head large, three elevenths of the total length, rounded across the 
crown, narrow at the throat, the sides converging rapidly from the middle 
of the eye, pointed at the snout, nearly one third deeper than wide. Snout 
long, hardly as long as the eye, chin produced to form the angle at the ex- 
tremity. Eye large, rather longer than the snout, more than twice the 
width of the interorbital space. Mouth wide, upper border formed by the 
intermaxillaries ; maxillary not reaching to the middle of the eye, curving 
up and backward on its hinder margin; lower jaws longer, prominent in 
front of the upper. Teeth very small, subconical, strongly-hooked, in villi- 
form narrow bands on the jaws, the sides of the vomer, and the forward 
portions of the palatines. Lingual teeth present, but hardly perceptible. 
Nostrils small, close together, nearer to the front edge of the eye than to 
the end of the snout. Interorbital space narrow, less than half as wide as 
the eye, slightly concave. Opercles thin, flexible. Gill openings very wide; 
membranes not united, free from the isthmus. Four gills, a slit behind the
