Abudefduf antjerius (not Cuvier) Fowler, Copeia, No. 58, June 18, 1918, 

 p. 64 (Philippines). — Fowler, Proc. Acad. Nat. Sci. Phila., 1918, p. 54 

 (Philippines) . 



Depth 2}4 to 21^; head 3 to 33^, width \% to \%. Snout 33^ 

 to 33^; eye 3 to 3 3^, about equals snout or interorbital, larger in 

 young; maxillary % to eye, to front eye edge in young, 33^ to 33^ in 

 head; interorbital 3% to 43^, broadly convex. Gill rakers 8 + 14, 

 lanceolate. 



Tubes 17 in lateral line, pores in straight section 7 or 8+ 1 or 2; 

 3 scales above lateral line to spinous dorsal origin, 8 below, 14 pre- 

 dorsal; 2 rows of cheek scales, infraorbital and preopercle flange 

 naked. Scales with 9 or 10 basal radiating striae; apical denticles 

 68 to 125, with 2 or 3 transverse series of basal elements; circuli very 

 fine. 



D. XIII, 13, I, variably 9, i, thirteenth spine 2 to 23^ in head, 

 seventh ray 1% to 2%; A. II, 12, i, second spine 2 to 2 3^, seventh 

 ray 13^ to 13^; caudal 1 to 13^, well emarginate; least depth of 

 caudal peduncle 2 to 23^; pectoral lr& to 13^; ventral 23^ to 33i in 

 combined head and body. 



Body largely uniform chocolate brown, bases of scales only showing 

 slightly darker. Usually short gray blue line on side of snout to eye 

 and another usually broader, more extensive, along lower edge of infra- 

 orbital. Some examples with gray blue spots on cheek and opercle. 

 Some examples also show gray lines or vertical blotches on some of 

 scales on costal region, variably extensive. Iris brown. Dorsals 

 brownish, paler basally, margin of spinous fin rather deep grayish 

 and blackish blotch, variably rounded to angular on last dorsal rays 

 basally. Also sometimes it extends backward little on front of caudal 

 peduncle. None of our examples show^ it ocellated as in Bleeker's 

 figure. Caudal and caudal peduncle pale yellowish brown, uniform, 

 or even hind marginal portion of caudal lobes little brownish. Anal 

 dusky brown. Pectoral pale yellowish, rarely or symmetrically with 

 dusky blotch and upper front edge of fin narrowly dusky. Ventral 

 dusky, often little paler, at least marginally, in young. 



East Indian region. Our specimens agree largely with Bleeker's 

 figure, except as now preserved all have pale uniform caudal peduncle 

 and caudal fin in contrast. Some also show abdomen or breast quite 

 pale. This is one of the smaller, modestly colored species, though the 

 black blotches variable. 



1 example, Batan, Rapurapu Strait. June 5, 1909. Length, 27 mm. [1606.] 

 Body slaty; top of head and anterior body bright red; median and three lateral 

 stripes above eye of narrow blue, limited on each side with black; these break into 

 dots posteriorly ; below eye two or three irregular stripes of dots parallel to above; 

 dorsal red, crossed by about three bars of blue; large black centered blue-rimmed 

 ocellus on soft fin; caudal 3''ellow, base whitish; anal dusky; ventrals blackish; 

 pectorals dusky yellow with small black spot in upper axil.
