48 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 62. 
spicuous black blotch, little smaller than pupil, at origin of pectoral 
fin and adjoining forward pale or whitish area of nearly equal 
extent. Iris dull bluff-yellow. 
Length, 70 mm. 
Type—Cat. No. 76644, U.S.N.M. Takao, Formosa. Dr. Fred 
Baker. 
Only the type known. In some respects the species superficially 
resembles Pomacentrus jerdoni Day, of which we have compared a 
Philippine example in the Academy. This is largely in general col- 
oration of the preserved examples and the black blotch at the pec- 
toral origin. The structural characters of distinction for P. for- 
mosanus are the shorter body and greatly smaller scales. 
(Named for Formosa.) 
ABUDEFDUF COELESTINUS (Cuvier). 
One 142 mm. long. Cebu. Compared with Samoan and Philip- 
pine material in the Academy. 
ABUDEFDUF CURACAO (Bloch). 
Head, 34; depth, 14; D. XIIT, 12,1; A. IT, 18, 1; tubular scales 18 
in upper arch of lateral line and 8 pores in horizontal hind section to 
caudal base; 3 scales above lateral line to spinous dorsal origin, 10 
below to spinous anal origin; 27 predorsal scales; snout, 34 in head; 
eye, 3; maxillary, 2}; interorbital, 24. Teeth uniserial, truncate in- 
cisors. Suborbital and preorbital edges entire. Gill-rakers, 8-+-20, 
14 in gill-filmaments or 2 in eye. Scales with 9 or 10 marginal 
striae and often 2 to 10 irregular or incomplete auxiliaries, apical 
denticles 120 to 170, circuli very fine. Color in alcohol olivaceous on 
back, paler to whitish below. Four broad transverse or vertical 
bands of olivaceous-dusky; first at predorsal and front of spinous 
dorsal to pectoral base and postventral region; second from middle 
of spinous dorsal to spinous anal; third from last dorsal spines; 
fourth on caudal peduncle. Spinous dorsal dusky, fins otherwise 
pale. Pectoral and ventral pale yellowish. Length, 110 mm. Zam- 
boanga. 
Our example differs a little from Bleeker’s colored figure of Gly- 
phidodon trifasciatus in that its bands are less sharply defined. He 
shows two dark bands from the front of the spinous dorsal, whereas 
in our example they largely appear as one. The species is variable. 
Three Philippine examples in the Academy, though structurally in 
agreement, show the first and second dark transverse bands quite 
diverse. 
ABUDEFDUF LEUCOGASTER (Bleeker). 
Head, 32; depth, 18; D. XIII, 11,1; A. II, 12; tubular scales 17 
in upper arch of lateral line and 8 pores in horizontal hind section
