246 DEEP SEA FISHES. 
The twelve (in cases eleven) branchiostegal light facets occupy the intervals 
between the rays. 
Black, lighter on fins and snout, silvery on cheeks, eyes, and flanks. 
The silvery area of the head passes through the eye across the cheek to the 
suboperculum. Below the scales the skin appears more or less of silver 
color. Linings of mouth, gill chamber, and belly black.

Apparently this species is less slender than Cyclothone acclinidens. The 
positions of the fins, and the formule, do not vary greatly from those of 
that species, but the coloration is very different; it is in this that the 
greatest distinction occurs. The colors of each of these species were taken 
from fresh specimens, and the figures, Plate J, figs. 3 and 4, show them 
as they existed at the time. In the present types the ground color was 
white ; on this the eyes and light organs appeared black with silver facings, 
the belly was blackish, from the black abdominal linings, tinted with bluish, 
and near the edges with reddish, and there were blackish markings in 
various parts of the surface: a pair of elongate spots on the forehead, 
diverging from the nape toward the eyes, a series of transverse streaks on 
the flank, as if to outline the vertebre, a broken line along the flank, a 
series of spots along the bases of the rays on dorsal and anal, a group of 
several spots behind the angle of the mouth, a group behind the abdominal 
cavity on the flank, several spots on the base of the tail, and a transverse 
streak across the bases of the caudal rays. 
The light facets are comparatively large ; below the eye one is present ; 
there are eleven in the branchiostegal series, four or five on the isthmus, 
fifteen or sixteen between the isthmus and the anal, and fourteen or fifteen 
from the anal to the caudal. 
On these specimens the teeth may be pressed forward against the jaw 
to spring out again on removal of the pressure, but whether the animal can 
place its teeth close along the jaws and extend them out at will in life is
