ICHTHYOLOGY OF VENEZUELA — SCHULTZ 139 



lateral line; posterior tip of premaxillary process not reaching to verti- 

 cal from center of eye, its length (from tip to snout), 1.8 to 2.4 in 

 distance between its posterior tip and origin of spinous dorsal fin; 

 second anal spine shorter than diameter of eye, more than 3 in distance 

 between posterior tip of premaxillary process and origin of spinous 

 dorsal fin; spinous dorsal fin more or less dusky, but without a jet- 

 black blotch at its tip, or definite whitish or colorless area below it. 

 4o. Greatest depth of body 2.3 to 2.6, usually 2.4 or 2.5 in standard length; 

 head 2.8 to 3.1, usually 2.9 or 3.0 in standard length; the distance 

 between tip of snout and origin of spinous dorsal fin, 2.1 to 2.3, 

 usually 2.2 in standard length; eye 2.7 to 3.1, usually 2.8 to 3.0 in 

 distance between origin of anal fin and caudal base; area over 

 premaxillary processes usually crossed by scales anteriorly leaving a 

 naked area behind. Eucinostoraus gula (Cuvier and Valenciennes) 

 46. Greatest depth of body 2.8 to 3.3, usually 2.9 to 3.2 in standard length; 

 head 3.1 to 3.5, usually 3.2 to 3.4 in standard length; the distance 

 between tip of snout and origin of spinous dorsal fin, 2.3 to 2.5, 

 usually 2.4 in standard length; eye 3.1 to 3.6, usually 3.2 to 3.5 in 

 distance between origin of anal fin and caudal base; area over pre- 

 maxillary processes usually depressed and narrowly U-shaped some- 

 times slightly restricted by scales anteriorly. 



Eucinostoraus argenteus Baird and Girard 

 36. Gill rakers 8 on lower limb of first arch (not counting rudiments or gill 

 raker at angle); maxillary less than 2.3 in distance between posterior 

 tip of premaxillary process and origin of spinous dorsal fin, usually 

 about equal to, or somewhat greater than perpendicular distance 

 between origin of spinous dorsal fin and lateral line; posterior tip of 

 premaxillary process reaching to or somewhat beyond vertical from 

 center of eye, its length (from tip of snout) 1.3 to 1.8 in distance 

 between its posterior tip and origin of spinous dorsal fin; second anal 

 spine equal to or greater than diameter of eye, less than 3 in distance 

 between posterior tip of premaxillary process and origin of spinous 

 dorsal fin; spinous dorsal fin with a conspicuous jet-black blotch at 

 its tip, separated from the basal dusky area by a whitish or colorless 



area Eucinostoinus pseudogula Poey 



26. Funnellike cavity in anterior interhaemal bone less conspicuous, more than 

 4 times as long as wide, the lateral ridge high and reaching beyond lower- 

 most part of edge of funnel; anal rays II, 8; greatest depth of body 3,1 

 to 3.5, usually 3.2 to 3.4 in standard length. 



Eucinostoinus lefroyi " (Goode) 

 16. Anterior interhaemal bone spoon-shaped; maxillary shorter than second anal 

 spine, less than diameter of eye, somewhat less than least depth of caudal 

 peduncle; second anal spine less than 2.6 in head, usually about equal to, 

 or slightly longer than distance between tip of snout and center of eye; 

 snout shorter than second anal spine; pectoral fin scaled.
