NO. 1853. FOUR NEW PHILIPPINE FISHES— RADCLIFFE. 255 



tinct, well separated, the anterior provided with a raised flap; inter- 

 orbital 4.55, rather broad, nearly flat; preopercular margin serrate; 

 intramarginal preopercular crest weakly serrate, the serrations least 

 distinct at angle and on lower border; orbital bones smooth or with 

 slight traces of serrations; small, regular, villiform teeth on jaws, 

 vomer and palatines; peritoneum silvery white; scales regular, firm, 

 ctenoid, somewhat deeper than long; 27 pores in lateral line. 



Dorsal spines strong, first 2.38 in second, 5.55 in third, second 1.94 

 in third, third longest and strongest, 1.72; soft dorsal somewhat 

 higher, 1.61, its distal margin obliquely truncate; caudal forked, 

 lobes rounded; anal 1.92, its distal margin sinuous; ventrals 1.51, 

 not reaching base of anal, their base a little in front of base of pec- 

 toral; pectoral 1.39. 



Color in alcohol: Ground color yellowish bronze with iridescent 

 reflections; four stripes on side and one along middle of back, hght

reddish brown in color, varying in width, but approximately equal 

 to interspaces; the median dorsal stripe begins above anterior margin 

 of eye, divides on nape, following row of scales along base of dorsals, 

 uniting behind soft dorsal, continues to base of caudal; from front of 

 dorsal posteriorly it is broken up into a series of blotches, one on each 

 scale; the first lateral stripe, narrower than the others, joins its fellow 

 near tip of snout, in this respect differing from arouhiensis and novem- 

 fasciata, extends backward over eye, touching upper half of anterior 

 scales of lateral line, decurved near base of caudal, the coloration 

 rapidly fading out on rays; a short stripe of lighter color crosses upper 

 fourth of eye, below pores of lateral line to eleventh scale, where it is 

 decurved and merges into second stripe; the latter encircling snout, 

 passes through middle of eye to base of caudal, enlarging into a darker 

 colored blotch at this point, a dusky shade along caudal to tips of 

 median rays; the third from middle of maxillary, along lower border
