Habitat : Coast of California from San Diego to San Francisco. This species is 
but rarely found at San Diego, only one or two specimens having been seen there. It 
is, however, one of the commonest species of Embiotocidce in the San Francisco markets. 
Body elliptical, ventral profile much straighter than dorsal; caudal peduncle 
slender, head considerably depressed above the eye ; lower jaw included ; rays of dorsal 
fin equaling or higher than spines. The maxillary reaches about eight-ninths distance 
to front of orbit, included under the orbital; premaxillaries anteriorly about on a level 
with lower rim of pupil. The anal fin very short, placed far back, the rays closely 
crowded together and spines small; fourth to sixth dorsal spines highest.
