Squalus Carcharlas ?
I had no opportunity of examining the numerous sharks of the Gambia,
and neighbouring ocean, but they appeared to be of the species common
to all seas.
Tetraodon Lmvissimus, Bowd., fig. 18.
This new species of Linnaeus's genus Tetraodon has no spines, nor any
visible branchial orifice. The back and sides are of a beautiful rose-
colour, irregularly marked with a deep black; the belly is of a fleshy
hue, and the lips are red; the pectoral fin has 13 rays, and the anal,
dorsal, and caudal fins, each 7 rays. It is found at Porta Praya, in the
Island of St. Jago;
Balistes Radiata, Bowd., fig. 45.
The ventral fin of this species seems to be more decided than that of
any yet known, and probably classes it with the sub-genus Triacanthus
of Cuvier. Its distinct rays, 8 in number, and its very strong spine,
have so positive an appearance, that we with difficulty admit the generic
character of having no ventrals. There are two small spines, and a very
strong one} in the first dorsal fin, the lower part of which is rayed with
blue; the second dorsal has 27 rays, six of which are considerably
prolonged beyond the membraneous part of the fin, they are of a yellow
colour, and the rest of the fin is spotted with yellow. The caudal fin
has 12 branching rays, the pectoral 13, and the anal 25; the latter is of
a blue colour, spotted with brown; the body of the fish is gray, spotted
with black, and lighter towards the belly. There are two large orange
patches, and one white spot behind the pectoral fin; 14 rays of a bright
lilac encircle the front of the eye, and there are two rays of the same
colour in the iris; three rows of small scales cover the bottom of the
second dorsal and anal fins: the teeth are disposed in the manner
represented in fig. 45, b. Found at Porta Praya.
Hippocampus.
I only saw a dried specimen, which was too carelessly preserved for me
to determine the species, but it was of a considerable size. !H
