Dorsal fin originating above base of pelvic fin, ending above anal fin origin; predorsal 

 length 54% of standard length, and 114% of prepelvic length; with one or two procurrent 

 rays, eight rays. Anal fin small, with one procurrent ray, seven or eight fin rays. Anal fin 

 longer in females than in males. Caudal fin deeply forked, lobes nearly acute, with eight 

 or nine dorsal procurrent rays, seven or eight ventral procurrent rays, and 19 (10+9) prin- 

 cipal rays. 



Scales small, especially on belly. Scales poorly-embedded or well embedded on sides, 

 deeply embedded ventrally. Scales on the caudal peduncle less embedded than that the re- 

 maining body. 



No cephalic line pore present in individuals less than 25 mm standard length. Left and 

 right supratemporal canals short and far from each other, with six pores. Supraorbital ca- 

 nal broadly interrupted at different points, with 10 pores. Otic canal with five pores. In- 

 fraorbital canal with 13 pores. The preopercular canal with 12 pores. Mandibular canal 

 with four pores. 



Body lateral line varying from absent in young to complete in adults. Body lateral line 

 straight in adults and extending from posterior of the opercle to base of the caudal fin. 

 Lateral line interrupted in different places. Pored scales about 62.
