 diameter; nuchal cirrus single, simple; snout profile with backward 

 slant of about 15 to 20 degrees from the vertical; upper lip crenulate; 

 lower lip smooth; lateral line broadly arched over pectoral fin, curving 

 to midlengthwise axis of body over region of anus and ending there; 

 vertical line through dorsal origin passes through pelvic bases; dorsal 

 fin with a deep notch at last spine, last soft ray with membrane at- 

 tached to dorsal edge of caudal peduncle; anal origin about under 

 base of second from last dorsal spine, last anal ray without membrane 

 attaching it to caudal peduncle; pectoral fins reaching only about %

 in adult male; posterior canine tooth each side of lower jaw present; 

 teeth fine, numerous, movable of equal size in both jaws; distal edge of
