ICHTHYOLOGY OF VENEZUELA — SCHULTZ 119 



brown blotch circled with pale, then posteriorly at base of fin a dark 

 circle; a dark bar extends downward from eye ending on subopercle; 

 pelvic fins very dark brown or blackish; anal and pectorals brown; 

 membranes near tips of dorsal spines anteriorly blackish; soft dorsal 

 mottled with brownish. 



Paralabrax dewegeri is related to that group of fishes now represented 

 by the following species: humeralis Cuvier and Valenciennes, cal- 

 laensis Starks, castelnaui Jordan and Eigenmann, clathratus Girard, 

 nebulifer Girard, maculatofasciatus Steindachner, maculata Howell- 

 Rivero, tortugarum Longley, and beta HUdebrand. 



From nebulifer and maculatofasciatus (of Pacific coast), which have 

 the third dorsal spine much longer than the fourth, it differs by having 

 the third dorsal spine a little shorter than the fourth, and in having 

 fewer scale rows above the lateral line; clathratus (of Pacific coast) has 

 more scales, 90 to 100, and more gill rakers, 20 to 24 on the lower part 

 of first arch, instead of 75 and 13 or 14 respectively for dewegeri. Two 

 other Pacific coast species, humeralis and callaensis, have 18 to 22 gill 

 rakers on the lower part of first gill arch and the former has too many 

 scales. Paralabrax maculata Howell-Rivero of the Atlantic has but 

 X,ll dorsal rays and only 45 scales. P. castelnaui from Rio de 

 Janeiro has but X,12 dorsal rays. There remain two species that 

 may be related to the Venezuelan one, but not closely: They are 

 Serranus tortugarum Longley (Carnegie Inst. Washington Year Book 

 No. 34, p. 87, 1935; Longley and Hildebrand, Carnegie Inst. Washing- 

 ton Publ. 517, p. 238, fig. 8, 1940 [south of Tortugas, Fla.]) and Serranus 

 beta Hildebrand in Longley and Hildebrand (l. c), p. 239, fig. 9, 1940 

 (south of Tortugas, Fla.). Both of these species have too few soft 

 dorsal rays, X,ll or 12 and X,12, and, in addition, too few scales, 50 

 or 60, respectively.
