FISHES. 
face, breast, and belly to the anal fin, are of a deep carnation colour; posteriorly the 
body is coloured with light green and vertically oblong spots of brown ; still more 
posteriorly, and above, it is dark olive green; abroad band vertically margins the straight 
caudal fin, on the base of which scales encroach ; and lines converge to the margin of 
the orbit beneath.” — C. 
The other fishes observed at Loo-Choo were a new species of Scarus, L.?, a variety ? 
of the Exocodus volilans, L., in which the pectoral fins, brown and dirty yellow spotted, 
did not reach the caudal; this was taken in nets by the natives, and most probably used 
only as bait for Dolphins: a Tetrodon, L., “white beneath, with the back of a light slate 
ground, tinged with green and yellow, with darker patches, and spotted irregularly and 
variously with white; iris silvery, above and below golden, abdominal spines obso- 
lete” — C.: and the Batistes aculeatus, L. 
At the Bonin Islands but few fishes were observed: they included a Dentex, Cuv., a 
Glyphisodon, Cuv., a Pimelepterus, Lacep., a Xirichthys, Cuv.?, and a fish referred to the 
Gymnodontes, Cuv. The latter presents a remarkable form. It is “a somewhat trian- 
gular fish, the pelvic bones projecting backwards, and keeping the lateral parts of the 
abdomen extended ; about two feet in length, and having the dorsal (the second if two) 
and the anal fins falciform; the spines are short: above it is dark grey, spotted with a 
very dark brown, lighter on each side of the dorsal fin, and whitish beneath ; a lateral 
silvery white band, somewhat irregular on its edges, extends on a level with the pectoral 
fins from the mouth to the tail: the air-bladder is strong and simple; there are two large 
milts, and portions of crustaceous animals were found in the stomach.” — C. The Dentex 
possessed “four hooked teeth in the upper jaw, and two in the lower, the latter so 
placed as to be on the outside of the four upper when the jaws are closed, and having 
two smaller intermediate teeth: the colour is greyish silvery, with somewhat indistinct 
yellowish silvery longitudinal bands below the lateral line: all the fins are inclined to 
red; the dorsal has ten, and the anal three, spines: the upper jaw is extensile: the 
stomach is en cul de sac; there are three short cceca; the testes are unequal, obtuse and 
joined before the anus, of a reddish colour ; the air-bladder is large and simple ; there 
are two eminences set with pharyngeal teeth, their crowns being flattish and rounded ; 
the lower pharyngeal teeth are indistinct.” — C. 
On the coast of California, at Monterey, Mr. Collie’s notes mention the occurrence of 
a species of Sparus, of two Scombri, and of a Clupea. The first of the Scombrida is 
apparently a Scomber, Cuv.; it was “ smaller than the Mackarel ; it was marked on theback 
with cross waved narrow bands of black and greenish blue; its first dorsal fin had nine 
spines, and there were four small pinnules behind the second dorsal and the anal: it had 
a simple air-bladder of moderate size, and an immense number of cceca, with a stomach ex- 
tending the whole length of the abdomen, narrow, tapering to the posterior part, and covered 
throughout nearly its whole length with the milt.? Its internal membrane forms longi- 
tudinal folds ; the intestines have three convolutions.” — C. This fish occurred in 
shoals. The second species was met with but once. It is a Caranx, Cuv., of which “the 
teeth in the upper maxillary are scarcely to be felt: the pectorals reach nearly to
