 Penultimate trunk segment septangular in a decidedly pre- 

 dominant number of specimens, sometimes novemangular. 

 Attains to but a medium maximum size.

 specimens of both sexes. Pectoral rays 15 to 18. 

 i^. Caudal segments modalh' 39, varying 38 to 40; dorsal rays 

 modally 20, varying 19 to 21. Snout averaging shorter, 

 postorbital longer, trunk longer and slenderer (see table 

 2). White dots coarser and more numerous. Atlantic

 modally 19, varying 18 to 21. Mediterranean coast of

K^. Snout 5.9 to 7.3 percent of length in medium-sized specimens 

 of both sexes. Pectoral rays 13 to 15. Caudal segments 

 36 to 38. Dorsal ra5^s 17 to 19. Atlantic coast of Europe. 



europaeus (p. 546) 



/-. Trunk with large yellowish or whitish or variegated blotches in 



young, usually partly or wholly replaced with brownish lines 



in full-grown specimens. White dots on side of trunk very 



sparse. Western Atlantic. 



g^. Caudal segments usually 36 to 38, varying 35 to 39; dorsal and 



pectoral rays in comparatively smaller average numbers; 



trunk in full-grown specimens rather deep; tubercles well 



developed; snout medium; white dots usually not profuse. 



Atlantic and Gulf coasts of United States, north and west of 



Florida hudsonius hudsonius (p. 551) 



g2. Caudal segments usually 35 to 37, varying 33 to 37; dorsal and 

 pectoral rays in comparatively larger average numbers; trunk 

 in full-grown specimens notably deep; tubercles compara- 

 tively not so well developed, sometimes nearly obsolescent 

 in full-grown males; snout rather long; white dots usually 

 profuse except on side of truak. Florida and Cuba. 



hudsonius pxinctulatus (p. 561) 



g^. Caudal segments usually 35 or 36, varying 33 to 36; dorsal rays 



in comparatively smaller average numbers; pectoral rays in 



medium numbers; trunk of medium depth; tubercles usually 



rather low, tending to become nearly obsolescent in large males; 



snout medium. Bermuda hudsonius kincaidi (p. 568) 



e^. Tubercles on upper ridge in medium-sized and large specimens ob- 

 solescent or nearly so, or very low and narrowly rounded above, 

 not pointed, not forming broad stout stumps. Typically covered 

 profusely with small brown spots. 

 p. Snout 6.1 to 7.9 percent of length and depth 16.4 to 19.4 in speci- 

 mens 68 to 104 mm long. Pectoral rays modally 14, varying 

 13 to 15. Coronet blunt but not low. Tubercles on upper 

 ridge of trunk usually evident as low rounded elevations.

p. Snout 10 to 12.7 percent of length and depth 12 to 15.3 in speci- 

 mens 58 to 137 mm long of both sexes. Pectoral rays usually 

 15 or 16, varying 15 to 17. Coronet very low. Tubercles on 

 upper ridge of trunk mostly obsolescent in large specimens.
