blenniidae: salariinae — schultz and chapman 321 



Remarks. — The darkly pigmented spots on this species occurred 

 along the midlengthvvise axis, whereas in R. rhabdotrachelus the dark 

 pigment spots were a little above that axis, especially posteriorly; the 

 dark spot at midbase of caudal fin was persistent even in the smaller 

 specimens.

 4.1 to 4.7; snout tip to anus 2.4 to 2.5; anal fin base 1.9 to 2.1; all 

 in standard length. Eye 3.5 to 4.2; snout 3.1 to 3.5; postorbital 

 length of head 1.6; greatest depth of body 1.3 to 1.4; least depth 3.0 

 to 3,2; longest pectoral ray 1.0 to 1.1; longest dorsal spine 2.0 to 2.1;

Orbital tentacle simple, slender, rounded in cross section, its length 

 from half to nearly as long as eye diameter; no nuchal cirrus; nasal 

 cirrus simple, short, snout profile with a slight backward slant of 

 about 5 degrees from the vertical; edge of both upper and lower 

 lips smooth; lateral line arched over axil of pectoral, descending 

 to near midlengthwise axis of body opposite last third of length 

 of pectoral fin and ending opposite tip of pectoral fin, notably in 

 front of a vertical line through anus; vertical line through dorsal 

 origin passes through base of pelvic fins; dorsal fins without an 

 emargination over last dorsal spine; last soft dorsal ray with a mem- 

 brane attaching it to dorsal edge of caudal peduncle but not to caudal 

 fin base; last ray of anal fin with a membrane attaching it to ventral 

 edge of caudal peduncle ; anal fin origin under base of second or third 

 from last dorsal spine; pectoral fins reaching to anus; anal spines 

 small, in females the first embedded; fij'st anal rays of adult males 

 not notably swollen at tips; posterior canine on lower jaw present;
