Description. — Segmented dorsal fin rays 14 or 15 (15 in 84 percent 

 of specimens); segmented anal fin rays 15 or 16 (16 in 89 percent of 

 specimens) ; posteriormost anal pterygiophore supporting 1 or 2 

 external elements (supporting 2 in 92 percent of specimens) ; total 

 giU-rakers on first arch 15-23 (16-20 in 94 percent of specimens); 

 pseudobranchial filaments 4-7 (6 in 76 percent of specimens) number 

 not increasing with increase in SL; vertebrae 34 (10 specimens); 

 supraorbital cirri 1-8, number increasing with increase in SL (table 

 54), main, or longest, supraorbital cirrus with most branches mesially, 

 sometimes with 1 or 2 branches laterally; nape with 1 cirrus on each 

 side; predorsal commissural pores 3-12 (usually less than 9), number 

 increasing with increase in SL (table 55) ; preopercular series of pores 

 with all positions with simple pores (only 1 specimen with 1 pair of 

 pores included in preopercular series) ; 1 pore before each anterior 

 nostril; lateral line pores terminating on side in area below and 

 between dorsal fin rays 4 and 7; ventral margin of upper lip crenulate 

 on lateral thirds, entire on middle third ; lip crenulae usually number- 

 ing 7-11 on each side. 



Proportional measurements: See tables 3, 4, and 56. 



No males with the skin of the anal spines and rays modified into 

 fleshy rugose pads were seen. It is presumed that all males available 

 were immature. The largest of these was 60.5 mm SL. The largest 

 female examined was 54.8 mm SL. The smallest specimen examined 

 was 18.5 mm. No ophioblennius stages were seen. 



Color pattern of preserved material. — The most striking and 

 characteristic marking of this species is a dark subquadrate blotch 

 in the humeral region between the pectoral axil and the lateral line. 

 This mark was present in all specimens examined. 



In specimens with the most developed color pattern there are seven 

 pairs of bands on the sides of the body (fusions between the mid- 

 portion of the members of a pair as in E. chiostictus were not noted). 

 Each member of the posterior six pairs of bands may be broken 

 vertically into tliree subquadrate sections, the middle section of 

 which is usually most intense (whether or not the band is broken 

 into sections), and the ventral section usually least intense. The 

 posteriormost two pairs of bands are usually paler than the others 

 and may be only dift'usely represented or absent. The anterior pair 

 of bands consists of an anterior, slender, dark to faint member and the 

 posterior much darker and larger subquadrate humeral blotch pre- 

 viously mentioned. The dorsal portions of the body bands extend
