Goryphopterus urospilus, new species 



Description. — Form moderately elongate; body compressed, rather 

 stout; head subtriangular in cross-section, the height directly behind 

 eyes subequal to the greatest width at same point. Mouth rather small, 

 terminal, a horizontal through distal margin of upper lip passing ap- 

 proximately through lower margin of pupil; lower jaw about equal to 

 upper anteriorly. Maxillary rather short, its end falling under anterior 

 margin of pupil in male, slightly short of that point in female. An 

 elongate, soft, pad-like translucent area present under anterior half of 

 eye. Tongue entire, rather broad. Teeth in narrow bands of about four 

 rows at symphysis, tapering to two rows posteriorly ; teeth in outer and 

 inner rows moderately enlarged; in upper jaw outer row extending to 

 angle of mouth, a few enlarged teeth in inner row at symphysis ; in 

 lower jaw outer row confined to front, enlarged teeth in inner row 

 extending a little farther backward ; no caninoids. Shoulder girdle with- 

 out papillae. A rather feebly developed, short, fleshy ridge in front of 

 spinous dorsal, sometimes hardly perceptible. Scales on body ctenoid, 

 large, in 25-26 oblique rows to base of caudal ; anterior boundary of 

 scales marked bv a line extending approximately from origin of first 

 dorsal to upper posterior angle of opercle; no scales on antedorsal dis- 

 tance m front of that line, none on side of head ; rather large cycloid 

 scales on base of pectoral, on throat and on midline of belly. First dorsal 

 with 6 flexible spines (in all 8 specimens), the fin rather high, but 

 none especially prolonged, the third or fourth reaching base of first to 

 third ray of second dorsal in male, somewhat lower in female. Second 

 dorsal with 10 rays (in all 8); anal rays usually 10 (in 6), often 9 

 (in 2) ; posterior dorsal rays in the larger males reaching a vertical 

 through end of hypural or falling a little short, in smaller males and 

 females falling considerably short; those of anal not quite reaching as 

 far back as those of dorsal. Pectoral with 19 (in 4) or 20 (in 4) rays, 

 all connected by an interradial membrane, its posterior margin reaching 

 a vertical through base of second or third dorsal ray. Ventral with the 

 interspinal membrane of medium development, posterior margin of fin 

 reaching slightly past anus in male, reaching anus or falling a little 

 short in female. Caudal of medium length, truncate. 



Body with longitudinal rows of small dark spots; five rows on lateral 

 aspect of body, four on caudal peduncle; spots in lower two rows some- 

 what larger and darker, spots in upper three rows often connected by 

 faint lines, forming a network effect; the spots, especially those in the
