272 BULLETIN OF THE BUREAU OF FISHERIES. 
men 5 inches long from southern Negros has the body a little more slender (depth 2.60) and the caudal 
notch deeper, its depth being greater than eye. Otherwise this specimen is not different from the rest. 
In using the name Siganus oramin for specimens the most of which have a slightly emarginate 
tail and a dark blotch on the shoulder, while the figure of Bloch & Schneider shows a fish with a deeply 
forked caudal and without humeral blotch, we are of opinion that the poorly characterized Ampha- 
canthus guttatus, var. oramin, of Bloch & Schneider is not really different from the Amphacanthus dorsalis 
of Cuvier & Valenciennes. Doctor Giinther states that Teuthis dorsalis is without the dusky humeral 
spot, but later says that in the closely related Teuthis albopunctatus the shoulder spot becomes indistinct 
in older specimens. Were it not for the fact that Doctor Giinther found the depth of specimens of 
Teuthis albopunctatus to be 3.50 in the total, we should have no hesitation in regarding it as 
identical with the present species, from which it is unlikely that it is different. Some of Doctor 
Giinther’s specimens of Tewthis albopunctatus were from the Philippines. 
Family TRIACANTHID. 
TRIACANTHUS Cuvier. 
228. Triacanthus blochi Bleeker. 
Three specimens from Iloilo and four from Manila, 3 to 4 inches long. In life silvery white; face 
yellow; several large spots of yellow on side, one under each dorsal; dorsal spine black at tip; caudal 
peduncle dusky above, fins yellowish. 
Family MONACANTHID.

Tour specimens from Cuyo, 2.50 to 3 inches long, and one from Lubang, 2 mches. Color in life 
pale dirty green, slightly mottled; two incomplete dark bars across tail. 
Two specimens from Panay, recorded by Jordan & Seale as Monacanthus nemurus, belong to this 
species. It is well distinguished from M. nemuris by the oblique pale bar above the pectoral and by 
the stouter and more strongly serrate dorsal spine. 
Family BALISTIDA.

. 
231. Balistes flavimarginatus Riippell.

black on each scale; above, from mouth to eye and from eye to pectoral and about dorsals, mottled 
black; pectoral yellowish; two bands of dull green over snout to corner of mouth. : 
232. Balistes chrysopterus Bloch & Schneider.

A fine example from Cuyo, 6.50 inches. Colors in life: A yellow band over snout extending back- 
ward to below pectoral, its posterior portion salmon; on the snout the band includes a sky blue band 
which extends to the corner of the mouth; interorbital with four blue and three dark green bands, 
three of these extending below eye and uniting at base of pectoral; a black mark at base of pectoral 
and over gill-opening; a brown saddle in front of dorsal, extending forward and downward and merging 
into a dark area behind the gill-opening; spinous portion of caudal peduncle black; four parallel 
diagonal white bands from anal upward and forward to middle of body; fins colorless; lower parts white.
