The largest specimens that we have at our disposal have a length of 0.58 m, the smallest about 0.37
m. The dorsal outline of the fish runs almost straight from the tip of the snout to the dorsal fin, and only
from this point onwards is slightly bent; the ventral outline, on the contrary, near the anal fin makes a slight
curve, it slightly ascends from the ventral fins to the gill cover, but from there till the tip of the lower jaw it
ascends steeply. Behind the dorsal and anal fins the tail is patch shaped [?] extended and soon passes into a
small caudal fin. The body is becoming shallower to the front; but its greatest depth is found between the
ventral and anal fins, and the ratio body depth/ body length is ¼. The body is strongly compressed; the
ratio body width /body height is ½. The back is almost as broad as the middle of the flank, but ventrally the
body is tapering rather acutely. The head is of an average size; its length fits about four times in the total
length of the specimen. The dorsal surface of the head runs almost in a straight line towards that of the
back; its ventral outline on the contrary, ascends forwards so very steeply, that it, just like the mouth
opening, forms an angle of about 45 degrees with the dorsal outline of the head. Dorsally the head is a bit
rounded towards both sides; the width at the nasal openings is almost half of the width of the caudal part of
the head, where the ratio head width / head length is ½. The snout is very short and in lateral view is shaped
like a triangle with sides hardly longer than the diameter of the eye. The nasal openings, of which the upper
one on every side is slightly larger and a little more caudally situated than the lower one, are situated
between the tip of the snout and the eyes, but a bit closer to the eyes. The eyes are situated laterally, but
very close to the dorsal outline of the head; they are perfectly circular, and their diameter is about 1/5 of the
