HOLACANTHUS POTTERI Jordan and Metz. new species. 

 Plate 71, fig. 1. 



Dorsal XIV, 19; anal III, 18 or 19; scales about 45; transverse 

 series between anal and dorsal 20. Measurements in hundredths of 

 length: Head 32 ; depth 58 ; eye 1 1 ; snout 1 1 ; postorbital part of head 

 11; interorbital 10; depth of caudal peduncle 14; snout to dorsal 40; 

 snout to anal 63. 



Body short, ovate, deep, greatly compressed, deepest through base 

 of ventrals; dorsal outline more convex than ventral; snout bluntly 

 conic, or rounded ; profile from snout to dorsal gently, evenly curved ; 

 dorsal fin rather liigh, last spine equal to depth of caudal peduncle; 

 first spme short, inserted above posterior margin of opercle; spines 1 

 to 5 graduated, remainder about equal, slightly shorter than first ray; 

 soft dorsal evenly rounded, middle rays longest; caudal rounded; anal 

 similar to- soft dorsal, but tapermg more rapidly in front; anal spines 

 graduated, third the longest; ventrals inserted slightl}'' behind pec- 

 torals, outer ray of each somewhat filamentous, reaching to third anal 

 spine; pectoral reaching to above second anal spine. Eye rather 

 large, high, almost entermg profile; interorbital slightly convex; 

 nostrils near eye, anterior with small flaps on posterior border; lower 

 margin of preopercle with three spines, the upper one large, equal to 

 diameter of eye, and reaching nearly to base of pectoral; margin of 

 preopercle above with a series of 8 to 10 small, spine-like serrae; 

 opercle unarmed; suborbital with three or four very small spines on 

 posterior margin; gill-rakers numerous, slender; teeth fine, setiform, 

 in single series.
