Bony interorbital space wide; its width 117% of orbit length, and 34% of head length. 

 In young individuals (25 mm standard length), axis of olfactory organ short, not exten- 

 ding to middle of the organ, five primary lamellae present; in adult individuals (52.0 mm 

 standard length), axis extends to posterior portion of the organ, 1 1 primary lamellae pre- 

 sent. 



Body not strongly compressed. Its maximum depth 22% of standard length. Caudal pe- 

 duncle short and high, its length 25% of standard length, its depth 43% of its length. 

 Genital papillae short and small; longer and more slender in female than in male; its po- 

 sterior end far forward of anal fin origin. 



Pectoral fin fan-like, sharper in female. In breeding male, first four or five rays, especi- 

 ally the first one, thicker, stronger, and darker than rest of pectoral rays; segments of the- 

 se thick rays shorter and wider; 13-16 fin-rays, usually 14 or 15. Pelvic fin originating in 

 advance of dorsal fin origin, prepelvic length 50% of standard length; fin rays eight, oc- 

 casionally nine (two of the 17 specimens counted with nine rays). 

 Dorsal fin originating posterior to pelvic fin origin, predorsal length 57% of standard 

 length, and 113% of prepelvic length; with two procurrent rays and eight rays, only one 

 of the 1 8 specimens with nine rays. Anal fin originating under or slightly behind the in- 

 sertion of dorsal fin; with one or two procurrent rays and eight fin rays. Caudal fin shal-
