Dorsal vii-i, 9; anal ii,8; scales 3 + 6 — 25. 



General form oblong, compressed; head 2.68, regular in outline; 

 body slender, curvature of dorsal and ventral surfaces similar, depth, 

 2.86; caudal peduncle strongly compressed, depth 2.03, length, 

 1.37; eye 2.93, small; snout 3.73, pointed; mouth large, obhque: 

 maxillary 1.82, long, not reaching vertical from posterior border of 

 orbit; interorbital 5.12, flattened; margin of preopercle armed with 

 weak serrations; intramarginal preopercular crest and orbital bones 

 smooth or with traces of weak serrations; well-developed vilhform 

 teeth on jaws, vomer and palatines; peritoneum sUvery white; 

 scales regular. 



Dorsal spines slender, third longest, 1.80; height of soft dorsal 

 1.64, its distal margin nearly truncate, becoming concave posteriorly; 

 caudal forked; anal similar to soft dorsal, 1.78; ventrals 1.58; 

 pectoral 1.46. 



Color in alcohol: Ground color silvery white with three dark red- 

 dish brown stripes on sides and one along middle of back, width 

 about two-thirds that of interspaces; median dorsal stripe extends 

 from interorbital, dividing at nape, along base of dorsals, uniting 

 again behind dorsals and extending as a narrow line to base of caudal; 

 the first lateral stripe separated from its fellow by a median white 

 line, near tip of snout, extends over eye to upper base of caudal, 

 bends downward to meet the second near tip of median caudal rays; 

 the second margined above and below on side of snout by white lines, 

 encircles snout, passes through middle of eye to tips of median caudal 

 rays; the third from middle of maxillary along lower margin of eye, 

 through lower pectoral base, following curvature of belly to base of 

 caudal, then bends upward to meeting place of first and second ; a fourth, 

 quite distinct on head, from tip of mandible to near base of ventrals, 

 very indistinct on breast; two white lines on ventral surface of headj 

 spinous dorsal hyaline, tips of membranes posteriorly black; a black 

 bar margined above and below with white near base of soft dorsal to 

 tips of last rays, remainder of fin hyaline; caudal rays whitish, mem- 

 branes hyaline except portions crossed by connivent stripes; anal 

 similar to soft dorsal; paired fins hyaline; base and lower axil of 

 pectoral black, very characteristic of the species. This description is 

 of an example 7 cm, in length from tide pools at Gubat Bay, Luzon. 



There are 25 examples in the collection from the coasts of Luzon 

 to the Celebes. These have been compared with specimens from 

 Apia, Samoa, in the reserve series of the United States Bureau of 

 Fisheries and with examples from the Fiji Islands in the United 

 States National Museum. The slender, compressed form, trim 

 appearance, narrow stripes connivent near tip of caudal, and black 

 pectoral base are characteristic of this species. 



In the original description of the species, Cuvier and Valenciennes 

 mention as types two specimens, one from Timor and the other from
