longest pectoral ray 1.0 to 1.2; longest dorsal spine 1.7 to 1.8; all in 

 length of head. Fleshy interorbital space 2.0 to 3.0 in eye. 



Orbital tentacle single, much broader than thick basally, tapering 

 to a point distally, its length from 2/3 to a little more than eye diam- 

 eter; no nuchal cirrus; nasal tentacle with from 2 to 6 short chri; 

 snout profile with a backward slant of about 10 to 20 degrees from 

 vertical; both lips smooth edged; lateral line arched over pectoral fin, 

 then ending above midlengthwise axis of body about opposite anal 

 fin origin ; vertical line through dorsal origin passes a trifle in front of 

 pelvic bases; dorsal fin with moderately deep notch over last dorsal 

 spine; dorsal fin with membrane attaching last ray to upper edge of 

 caudal peduncle but not to base of caudal fin; anal origin under base 

 of next to last dorsal spine; last anal ray without membrane attaching 

 it to caudal peduncle; pectoral fin not quite reaching to anus; anal 

 spines small, embedded in females; first few anal rays, in adult males 

 with slightly swollen smooth tips; posterior canines present in lower 

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

 margin of caudal fin truncate to slightly rounded or a little undulating; 

 no cephalic crest developed in adult males. 



Color in alcohol. — Background coloration of adult males light tan, 

 with numerous brown spots on head separated by whitish intercon- 

 necting narrow streaks or lines; those on body larger but not as dark;

Background coloration of females very light tan, with numerous 

 faint but distinct light and dark spots on head and some on body, the 

 latter when examined microscopically are made of groups of b.'ackish 

 pigment cells; lower part of side a little above anal fin base with a 

 row of spots representing the obsolete vertical bars; dorsal and caudal 

 fins barred with small black spots; anal fin with a dusky spot basally

 first three dorsal spines with black spots. 



Color when alive. — Based on two kodachromes taken in field, one of 

 the holotype. Background coloration of males whitish below, tinged 

 with light pinkish brown dorsally, the white interspaces in alcohol 

 between the dark spots are light brick reddish, and form a reticulated
