Three species of this family were taken at the Cortes banks and 
three in the neighborhood of San Diego. All were taken from the 
mouths of Rock Cod. They are not found in the regions inhabited by 
Rock Cod except on stormy days, and it is only during rough weather, 
therefore, that they can be procured. The explorations of the Albatross 
would seem to show that in deep water there lives still another series 
of this family. 
The littoral species of this family, known from the Pacific coast of 
America, may be distinguished by the following key: 
a. Lat.1l.none. Greatly compressed. Scales crenulate..--... Tarletonbeania BE. & E, 
b, Origin of dorsal equidistant from tip of snout and base of caudal peduncle; 
ventrals reaching half way to 7th anal ray; no spines on caudal 
peduncle ; dorsal and ventral profiles equally arched . Tenia E.& E. 
bb. Origin of dorsal nearer snout than base of caudal; ventrals not reaching half 
way to vent; caudal peduncle with three spines above and 
below; ventral profile more strongly arched than dorsal profile.
