282 DEEP SEA FISHES. 
structure in J. ferox is like that in J. antrostomus and has the same functions. 
Ventrals small, narrow, as long as the cleft of the mouth, below the fifth 
dorsal ray. Caudal narrow, deeply forked, with ten short rays above and 
eight below. 
Black, with glandular patches appearing like transverse or longitudinal 
series of grayish blotches; caudal yellow; inflated portion of the barbel 
light.

SALMOIDS. 
Very few deep sea species belonging to this group are known, and none 
of them occur in the material of the present report. Argentina, Micros- 
toma, Pterothrissus, and Bathylagus are given places in the lists of deep 
sea genera by different authors; but most of the species are ordinarily 
taken near the surface and it is only those of Bathylagus which are marked 
bathybial with any degree of confidence, they being least likely to have 
entered the net near the surface. Of the haul in which the first discovered 
species of this genus was secured Mr. Murray says the dredge was in the 
water seven hours and did not appear to touch the bottom, yet it brought 
up the fish, shrimps, medusze, and other animals, most of which, as he thinks, 
were taken ‘“‘in the mtermediate water between a depth of 100 fathoms 
from the surface and a short distance from the bottom” (Narr. Chall. Exp., 
1,903). Bathylagus is the genus of most interest at this time because of its 
distribution. Though, like the others of the group, it cannot positively be 
called a fish of the bottom, the probabilities are that it lives at the greater 
distances below the surface. One of the species was obtained by the 
“Challenger” in the south Atlantic at a station for which the given depth 
is 2040 fathoms, and another was brought by the same vessel from the Ant- 
arctic, taken in a depth of 1950 fathoms; two species were caught by the 
“ Albatross”’ off the eastern coasts of the United States in depths ranging 
from 600 to 1769 fathoms; and two others, also obtained by the “ Albatross,” 
have been described from the northwestern coasts of the United States, the 
stations being of various depths between 322 and 877 fathoms.
