FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 35 



Amia koilomatodon (not Bleeker) Jordan and Seale, Bull. Bur. Fisher., 

 vol. 25, 1905 (190G), p. 240, fig. 34 (Apia and Pago Pago). — Evermann 

 and Seale, Bull. Bur. Fisher., vol. 26, 1906 (1907), p. 71 (Bacon).— 

 Fowler, Copeia, No. 5S, June 18, 1918, p. 63 (Philippine materials). 



Depth 2}4 to 2]/ 2 ; head 2}/ 2 to 2%, width V/ s to 2. Snout Z% to 

 4 in head from snout tip; eye 2% to ?>%, greater than snout or 

 interorbital or subequal with snout with age; maxillary reaches 

 opposite Yi to % in eye, expansion \% to 2}/$ in eye, length 1% to 

 2 in head; bands of villiform teeth in jaws, on vomer and palatines; 

 interorbital ^/i to 4%, nearly level; preopercle ridge and edge both 

 strongly denticulate; preorbital edge with age, also lower orbital 

 ridge, spinescent. Gill rakers 6 + 15, above and below 3 or 4 as 

 rudiments, others lanceolate, greatly longer than gill filaments or half 

 of eye. 



Scales 22 or 23 to caudal base and 4 to 6 more on latter; 2 above, 

 6 below, 3 or 4 predorsal, 2 or 3 rows on cheek; muzzle, including 

 maxillary, preorbital and interorbital naked. Tubes in lateral line 

 large, simple, each well exposed. Scales with 13 or 14 basal radiating 

 striae; apical denticles 122 to 194 with 1 or 2 transverse series of 

 basal elements; circuli fine and absent apically. 



D. VI-I, 9, i, second spine 1% to \% in total head length, first 

 branched ray 134 to 1^; A. II, 8, i, second spine 234 to 23^3, first 

 branched ray \% to \}/ 2 \ caudal 1-jV to l 1 ^, emarginated moderately 

 behind with lobes rounded; least depth of caudal peduncle 234 to 

 2H; pectoral \% to 1%\ ventral \% to \y 2 . 



Back and upper surfaces brown, lower and under surfaces paler. 

 From lower eye edge deep brown bar obliquely across cheek to 

 preopercle angle. Iris pale yellowish to brown, neutral or slate. 

 Dusk} 7 brown transverse band from bases of longest dorsal spines 

 down to level of pectoral, about scale or more in width and usually 

 broken or incomplete opposite body axis laterally. Second narrower 

 dusky brown transverse band from bases of last dorsal rays, extends 

 downward well toward anal, also similarly broken at body axis. 

 Small rounded dusk} 7 brown spot, less than half of pupil, at base of 

 caudal medianly. Fins all dull brownish, variously marbled or 

 clouded with darker, especially basally. Paired fins usually much 

 paler than others. Often small inconspicuous dusky spot at bases 

 of last anal rays. In small examples upper and lower caudal edges 

 show more distinctly darker in most cases. 



Only known previously from three examples Bleeker described 

 from Singapore. It is greatly like Apogon taeniatus as figured and 

 described by Day, but different. All our examples show the vertical 

 dark bands different. They are always broken, besides the second 

 extends from the bases of the last dorsal rays and not the median as 

 Day shows. They also differ in the ridge as well as the edge of the 

 preopercle denticulate. Day shows the ridge of the preopercle entire.
