Body strongly compressed, elongate. Caudal peduncle deep, com- 

 pressed, length about three-fifths its width. Head greatl}^ com- 

 pressed, width 2f its length. Eye small, round, elevated; hind edge 

 slightly advanced in head length. Maxillarj^ about two-thirds to eye, 

 not quite to front nostril. Lips rather fleshy. Teeth conic, even in 

 front of jaws, slightly curved, uniserial, pair of canines in front of 

 each jaw. Nostrils small pores, hind one level with upper eye edge 

 and close to its front edge. Interorbital convex. Rakers about 6 + 9 

 short points, one-fourth of iilaments; latter nearly long as eye. 

 Pseudobranchiae about three-fourths of fdaments. Head naked. 

 Scales reticulate medially, basal striae 23 to 47 and apical striae 11 

 to 24. Scales on breast smaller than sides, still more so on predorsal 

 and caudal base. Lateral line complete, high on back at first, drops 

 midway on caudal peduncle and tubes simple to four-branched. 

 Spinous dorsal inserted slightly before pectoral origin, slightly be- 

 hind in young, last spine longest or 3§ to 4| in head. Soft dorsal 

 inserted about opposite depressed pectoral tip, fifth ray 2J to 2^ in 

 head. Anal inserted little behind soft dorsal origin, third or largest 

 spine, 4^ to 4| in head; first anal ray, 2f to 3. Least depth of caudal 

 peduncle 1| to 2^. Caudal emarginate behind, corners pointed, 

 IJ to IJ in head. Caudal rounded convexly behind in yoimg. 

 Pectoral H to 1^ in head; ventral 1^ to 3-^ and inserted little 

 behind pectoral. Ventral nearer anal. 



Color in alcohol generally brown; lower surface paler. Each 

 scale with dark median and basal vertical line so whole trunk ap- 

 pears evenly and finely cross-barred. Membranes between first 

 three dorsal spines black. Also small black spot at pectoral origin. 

 Dorsals and anals each with lengthwise brown band medially entire 

 length of fins, otherwise pale brownish. Caudal pale yellowish, 

 edges above and below, also base, deep brown. Pectoral and ventral 

 darker at ends, general color broMTi. Iris pale brown. Young with- 

 out dark vertical lines very distinct, though broad longitudinal dark 

 band, from snout tip to caudal base medially, conspicuous. Length, 

 79 to 153 mm., three examples. Ascension Island or St. Helena. 



The smallest of the above is doubtless identical with Julis as- 

 censionis Quoy and Gaimard,* based on an example 90 mm. long. 

 Their figure shows the red band through the eye much narrower than 

 over the costal region, and a dark line transversely at pectoral base, 

 whereas in my example the small spot at the fin origin is character- 

 istic as in the larger examples. Quoy and Gaimard also figure a 

 scale showing but 11 basal and as many apical striae, which is a 

 lower number than I find for basal striae. The adult is next described 

 as Julis sanctae-helenae Valenciennes.^ Though Gunther only
