PISCES 165 
orbital space concave, its edges forming low ridges; the snout is 
flat but pointed in profile, its length little more than half that 
of the eye; nostrils small, close together, slightly nearer the eye 
than the snout, the anterior with a flap behind; the mouth is 
moderate, slightly oblique and the lower jaw projects noticeably 
beyond the upper, the maxilla reaches nearly to beneath the 
middle of the eye, and its distal extremity is one-fifth greater 
than the interorbital space; gills four, a slit behind the fourth, 
pseudobranchiz present. 
Body sub-cireular in section, with a ridge from the occiput 
to the beginning of the dorsal fin which stands on a slight 
eminence, lower surface of body rather flat. 
Teeth—A broad band of villiform teeth in the jaws; they 
extend outward over the lips, a large patch of similar teeth on 
the vomer, subcontinuous with a narrow band on the palatines; 
the tongue is spatulate and truncate, and bears teeth on the 
front and sides. 
Fins.—The dorsal commenees a little nearer the snout than the 
adipose fin, the first ray is half the length of the second, which 
is the longest, and more than four-fifths the length of the head, 
or one-third the height of the body, the remaining rays regularly 
decrease in length, the adipose fin terminates evenly with the 
anal, the rays of which are but three-fourths the diameter of the 
eye in length; the pectoral is equal to the ventral in length 1.4 
in the head and reaches below the hinder insertion of the dorsal; 
caudal deeply cleft, the upper lobe one-third longer than the 
lower, peduncle long, and, except quite posteriorly, as wide as 
deep. 
Scales.——Cheeks and upper part of opercle with scales smaller 
than those of the body, all cycloid and nearly smooth; the lateral 
line arises over the opercle and gradually attains the median line 
passing along the middle of the peduncle, minute scales along 
the ventral (which has an enlarged axillary), and caudal fins. 
Colours.—Green above and silvery below; head green with 
brilliant silvery opercles, edge of premaxillary blue, upper lip 
black, dorsal fin and caudal lobes tipped with black, the 
colouring on the lower lobe of the caudal broader than on the 
upper; inner rays of ventrals clouded. 
Length.—192 mm., attains to 210 mm. 
When we first obtained the fish I recognised it as of the same 
species taken so commonly off the coast of New South Wales in 
1898, and it is an addition to our marine fauna. C. mgripinnis
