NO. 2294. FISHES FROM WEST AFRICA— FOWLER. 259 



above, front one little lower or about three-fifths of pupil length before 

 eye. Interorbital broadly convex. Rakers, 3 + 9 or 10 weak points, 

 about 4 in filaments and latter 1§ in eye. Scales ctenoid, with about 

 14 basal striae, in oblique rows above and below lateral line, become 

 much smaller and greatly crowded over rayed vertical fins. Cheeks 

 with five rows of scales. Lateral line greatly arched; ends close 

 below last dorsal rays. Dorsal with stronger and slightly longer 

 spines in front; fifth spine, 1^^ to 1| in head; fin edge notched. Soft 

 dorsal rounded, fifth ray 1| to 2 in head. Spinous anal inserted 

 about midway between hind preopercle edge and caudal base; second 

 spine 2 in head, and fifth ray about If to 2. Caudal convex behindj 

 If to 1^ in head; pectoral, 1{; ventral spine, If to 1|. 



Color in alcohol pale brownish generally, lower or under surfaces 

 pale or whitish. Deep brown broad band begins just below and 

 before spinous dorsal origin, but not meeting its fellow on predorsal, 

 extends forward to eye, which it intersects, leaving hind portion of 

 iris whitish. This also continued below over cheek to front branchi- 

 ostegals. Second broad band begins on spinous dorsal, including 

 third to fifth spines, extends down, including pectoral base, hind 

 edge of opercle broadly to ventral base, though about haK its width 

 before these fins so its fellow converges. Third broad band extends 

 from last two dorsal spines basally and front dorsal rays basally, 

 down toward front of soft anal, narrowed and paler below, but quite 

 dark and conspicuous at its origin above. Dark transverse band 

 across caudal peduncle, followed by narrow white border. All dark 

 bands noted with rather narrow pale borders. Edges of soft dorsal 

 and anal dusky. Fins all pale, and caudal base with dull brownish 

 crescent transversely. Each scale on breast and along side of abdo- 

 men between dark bands with srqall pale spot. Two examples, 63 to 

 66 mm. 



Compared with examples of Chaetodon striatus (Linnaeus) from 

 Delaware Bay and the West Indies, 68 to 136 mm. long, one finds a 

 constant difference in coloration. In C. hoefleri the second broad 

 dark band extends more obliquely forward to include hind portion of 

 opercle entirely, besides pectoral and ventral bases likewise; third 

 band deeply black above and not joined by dark band on basal por- 

 tion of soft dorsal. Due to youth, likely, my examples of C. Tioefieri 

 differ somewhat from Steindachner's figure, as dark edges on soft 

 dorsal and anal are broader; second dark band extends more forward 

 to include more of opercle besides ventral base and area well before it.
