pectoral; dorsal and anal edged with gn anteriorly ; ventrals with 
considerable light yellow. 
This species is known to us from upwards of a hundred specimens 
taken in sweep-nets between the Golden Gate and Point Reyes. 
All the specimens are small, ranging from 8 to 12 inches in length. 
Its abundance, in the San Francisco market at least, seems to be con- 
fined to the month of April. 
Its relations are not intimate with the two species of this genus pre- 
viously known—ZH. platessoides of the North Atlantic and H. jordani of 
the North Pacific. From both it differs in the elongate form, much 
larger scales, fewer fin rays, smaller teeth, &c. With H. jordani, which 
inhabits the same waters, it agrees in scarcely any respect, excepting 
in the characters of the genus Hippoglossoides, 7. e., the large mouth, 
conical teeth, ctenoid scales, simple, straight, lateral line, convex caudal, 
dextral eyes, Se.
