One of the specimens from station 5518 contained in its stomach 
one of the horny jaws (1 cm. long) of some cephalopod. 
The lateral line courses along a low curve anteriorly. The large 
scales are in but four series between the lateral line and the origin of 
the second dorsal fin; they are covered with small suberect spinules, 
arranged in quincunx over most of the body, but aligned, more or 
less definitely, into strongly divergent series anteriorly, especially 
on the head. The scale characters of the species agree with those 
of quincunciatus in contrast with those of argentatus,; the median 
occipital scute is preceded by a similar scale on each side; a narrow 
scaleless groove extends backward along the upper surface of the 
snout just outside the series of scales bounding the median rostral 
series. The under surface of the head is completely scaled, with the 
exception of the gular and branchiostegal membranes, and of the 
rami of the mandibles, which have only a few scales posteriorly 
(the rami are completely scaled in C. quincunciatus). 
Fin measurements of specimens from southern Luzon—length of 
first dorsal base 1.2 (1.0 to 1.35) in the interval between the dorsal 
fins, 1.8 (1.65 to 1.9) in the length of the head behind the orbit; 
length of pectoral fin, 3.05 and 3.3 in the head (two specimens) ; 
outer ventral rays, 4.8 (one specimen) ; second ventral ray, 5.1 (one). 
Fin measurements of specimens from station 5518—first dorsal 
base, 0.9 and 1.2 interdorsal, 1.65 and 2.0 in postorbital; outer ventral 
ray, 3.6 (one specimen) ; second ventral ray, 4.65 (one). 
The origin of the anal fin is slightly before (or directly below) 
that of the second dorsal. 
The dark markings of the young become indistinct in the adult. 
In the specimen 150 mm. long there are several dark dorsal saddles 
anteriorly—one just before the first dorsal fin, another below that 
fin, a third below the posterior part of the interdorsal space and the 
anterior end of the second dorsal fin, and two posterior to these; of 
these saddles the penultimate and the one under the first dorsal ex- 
tend a short distance below the lateral line. Posteriorly the tail is 
crossed by dark vertical bars about as wide as the interspaces between 
them. The occipital region is dusky. The silvery area covers the 
sides of the head, the trunk below the lateral line, and the median 
third of the sides of the tail. The belly is dusky between the ventral 
fins and the isthmus and about the anus, from which region a black 
streak extends forward to an anterior elliptical dilation covering the 
eland-like organ in the body wall. The axil of the pectoral is black. 
The snout is dark along its margins and mid-dorsal line, and dusky 
below. The concealed region about the tip of the premaxillaries is 
dark; the inner wall of the sensory cavity just above the ventral
