163. Pomacentrus pristiger Cuvier & Valenciennes. alata. 
A single specimen, 3 inches long, from Cuyo. Dorsal spines 13; a black spot at tip of opercle. 
We follow Sauvage in identifying the present specimen with Pomacentrus pristiger (=littoralis of 
Bleeker, and Giinther, part). This species is near Pomacentrus tripunctatus Cuvier & Valenciennes 
(=trilineatus of Sauvage), but is distinguished by having all the suborbital denticulations equal, and 
by the absence of a black spot on the top of the caudal peduncle. 
The specimen from Cuyo had the following colors in life: Body dull dark green; fins dark brown; a 
line under eye and a spot in front of eye; some spots on top of head of a rich violet color; opercles faintly 
washed with violet. 
164. Pomacentrus littoralis Kuhl & Van Hasselt. 
Four specimens, 2 to 3 inches long, from Cavite, collected by Dr. G. A. Lung and recorded by 
Jordan & Seale under the name Pomacentrus tripunctatus Cuvier & Valenciennes, evidently belong to 
this species as redefined by Sauvage, from the types. The anterior suborbital denticulation is enlarged 
and followed by a notch, and there is a round black spot on the tip of the opercle, as in Pomacentrus 
tripunctatus, but the top of the caudal peduncle is without blotch; dorsal spines 13. 
165. Pomacentrus emarginatus Cuvier & Valenciennes. 
Two young specimens from Ticao and a well-colored adult, 2.50 inches long, from Cuyo, should 
probably be referred to this species; dorsal spines 13. 
We can find no differences between the species called emarginatus and chrysurus by Cuvier & Valen- 
ciennes. Sauvage states that Pomacentrus chrysurus has only two rows of scales on the preopercle. The 
scalesare in three rowsin our largest specimen, which has the caudal deep yellow, in strong contrast with the 
contiguous color on the caudal peduncle. All the other fins are without spots or ocelli. The two young 
specimens both have an ocellus at the back of the soft dorsal, like Pomacentrus delurus Jordan & Seale, 
but lack the fully developed third row of scales on the preopercle present in the type of Pomacentrus 
delurus as figured by Jordan & Seale. A cotype of P. delurus, however, agrees with the present specimens 
in having only two developed rows. It is probable that Pomacentrus delurus is the young of the forms 
called Pomacentrus emarginatus and chrysurus by Cuvier & Valenciennes, and it is not impossible that 
these in turn, when a full series is examined, will prove to be not different from Pomacentrus littoralis. 
166. Pomacentrus fasciatus Cuvier & Valenciennes. 
Two specimens from Ticao Island, 0.75 and 1.25 inches long. Color in spirits brown, with 4 light 
cross bands, narrower than the dark interspaces; one ot these crossing opercle, one crossing the body 
in front of the fourth dorsal spine, one originating at junction of spinous and soft dorsal, and the last one 
crossing the root of the caudal peduncle; the two middle bands are continued upward on the dorsal fin; 
on the top of the opercle there is a small black spot, and behind this several dark specks, forming two 
indistinct series, ceasing over tip of pectoral; the suborbital is smooth and the preopercle only weakly 
denticulated, or crenulate. 
ABUDEFDUF Forskal. 
167. Abudefduf saxatilis (Linneus). 
One specimen 2 inches long from Manila, and one from Calayan, 1.50 inches, in tide pools. Color in 
life of Calayan specimen: Pale bluish white; body and dorsal crossed by four vertical bands of dark- 
blue (washed out on belly), between which are three golden yellow areas; head black; belly white. 
168. Abudefduf dicki (Liénard). 
A single example from Cagayancillo, 3 inches long. Color in life brown; a black band at beginning 
of soft dorsal, the color behind the band light fawn; pectoral rich yellow. 
169. Abudefduf zonatus (Cuvier & Valenciennes). (Glyphidodon brownriggii Giimther, not of 
Bennett.) 
One specimen from Cagayancillo, 2 inches long. 
170. Abudefduf unimaculatus (Cuvier & Valenciennes). (Glyphidodon dispar Giinther.) 
Eight specimens from Calayan, 1.50 to 2.50 inches long, and one from Cagayancillo, 2.50 inches. 
These specimens have the dorsal xi, 12 or 13, and the anal m, 11 or 12, and each scale of the body with 
a more or less distinct vertical light streak, these forming longitudinal rows on the sides. Four of the 
Calayan specimens, probably males, have all the fins except pectorals dusky, the dorsal with a distinct 
black spot at the base of the last four rays. The others, probably females, have the body and fins paler,
