maxillary ending under pupil. Preorbitals coarsely serrate on lower 

 margin, their greatest width 7 in head. Preopercle toothed strongly 

 at angle, less strongly above, three larger teeth at angle very acute 

 in adults, longest less than half diameter of pupil. Serrations on 

 lower hmb abruptly smaller. Two opercular spines, the upper nearly 

 obsolete, lower very strong, extending the distance of length 

 of maxillary from hinder margin of preopercle. Clavicle with live 

 coai-se teeth, pointing back and upwards, of nearly same size as 

 those of preopercle. Post-temporal serrated similarly to preorbital. 

 Teeth in outer row conical, somewhat canine-like, not closely set, 

 larger near middle of jaw; mner bands villiform, and smaller in size. 

 Teeth on vomer and palatines present in young, but deciduous or 

 few in number in adults. 



Dorsals deeply divided; fh'st spme very small, usually lacldng in 

 adults and much longer in the very young. Fourth and fifth spines 

 longest, slightly less than two in head; penultimate three-fourtlis of 

 eye diameter; last 4^ in head, adnate to first ra}', which is 2|- in head. 

 Second anal spme 3|, third 4 in head, or equal to the second. First 

 anal rays nearly twice length of third spine. Soft dorsal, anal, and 

 caudal margms deeply concave. Pectorals short, 2 in head. Ven- 

 trals 1§ in head, not reaching anus. 



Scales small, roughly ctenoid, absent on inter- and preopercle, 

 suborbital regions, snout and jaws. A temporal band of four or five 

 series of scales present; a low sheath present along bases of dorsal 

 and anal. 



Body with three concentric black bands, first along bases of 

 dorsals from first spines to first ra3's, leavmg a clear space above m 

 which lies a black streak from sixth to tenth dorsal spines; second 

 from nuchal region to last dorsal rays, its upper edge passing through 

 lateral line, but not below; third narrower, from occiput to middle 

 caudal rays, fourteen scale rows below lateral band at its middle. A 

 black blotch on spmous dorsal from fourth to seventh spines, another 

 from ninth to eleventh or twehth. First four soft rays tipped with 

 black on distal halves, as are sixth and seventh, frequently a black 

 spot present on last two rays. Caudal with central longitudinal 

 stripe, an obhque band above and below, and upper lobe tipped 

 with black. Other fins colorless. Peritoneum clear. 



We have specimens of what is generally termed the same species 

 from Formosa (2); Swatow, Chiaa (4); Samoa (2); Austraha (2); 

 Arabia (1); Manila, Cavite, and San Fabian, Philippine Islands (5); 

 and Sumatra (1). Of these the Arabian specimen seems to be dis- 

 tinct in several respects. Its body bands are more convex, the upper 

 nearly touching the lateral line, the second droppmg four or five 

 scales below the lateral line instead of as above. The maxillar}^ ends 

 under the anterior margin of the eye instead of the pupil; the body
