The following counts were made, respectively: Dorsal rays 1,8 (1,9;

 base of anal to base of midcaudal fin rays 11 (11; 11; 11); plates in 

 front of dorsal fin always 4; spines on interopercle always 2 long ones 

 with 2 to 4 or 5 very short ones posteriorly on the interopercular bony 

 elements. For additional coimts see table 16. 



Head and body depressed, interorbital space a little convex; no 

 enlarged prickles around eye; prickles on head continuing to snout, 

 but there is a small naked area near tip of snout, on males a few 

 enlarged prickles occur at sides of snout; supraoccipital plate bounded 

 posteriorly by a paired plate; belly naked to anal fin; lips papillate; 

 the posterior margin of lower lip with about 20 to 25 lappets; teeth 

 on jaws bifid, slender, very numerous, 75 or more on each ramus; 

 spines of interopercle graduated, one very long spine reaching past 

 head, then a shorter one, both with hooked tips, then two to four or five
