diffuse; first dorsal spine of adult males elongate, and usually whitish; 

 fins all dusky except dorsal part of caudal and pectorals. 



Ecology. — C. quagga, like its relatives in the Marshalls, typically 

 occurs in the surf in the Lithothamnium ridge.

SPECIMENS STUDIED 



Bikini Atoll: 1 station, 2 specimens, 93 to 99.5 mm. in standard length. 



Rongerik Atoll: 2 stations, 4 specimens, 62 to 82 mm. 



Arno Atoll: 2 lots, 5 specimens, 45 to 81 mm. 



The above specimens represent the holotype and some of the paratypes. 



Description. — Certain counts are recorded in table 109. Dorsal 

 rays XII, 14 to 16, rarely 14 or 16; anal 11,15 or 16, rarely 15 (first 

 anal spine embedded on females); pectoral 14 to 16, rarely 14 or 16 

 (with lower 5 or 6 thickened) ; pelvics 1,4; bran^'-hed caudal rays 5+4; 

 fringe of cirri on nape 32 to 42, generally 35 to 42; nasal cirri 4 to 6; 

 supraorbital cirri 4 to 10 (more cirri on large adults). 



Head 2.9 to 3.1; greatest depth 3.1 to 3.3; longest dorsal spine 

 (first elongate in adult males) 1.9 to 2.9; longest thickened pectoral 

 ray 2.1 to 2.6; all in standard length. Eye 3.5 to 4.7; snout 2.4 to 

 3.1; interorbital space 7.7 to 13.3; postorbital length of head 1.5 to 

 1.7; least depth of body 2.5 to 3.0; greatest depth of body 0.87 to 

 0.96; all in length of head. 



Orbital tentacle with a broad flattened base, its distal edge with 

 numerous long cirri, more in adults; nuchal band of cirri simple, 

 those at middorsal line about same length as those laterally, nuchal 

 band of cirri curving posteroventrally so that the distance between 

 vertical lines through ventrolateral basal tip and anterodorsal edge 

 is contained 4.6 to 6.5 times in postorbital length of head; ventral 

 basal end of nuchal band of cirri is notably swollen and flattened even 

 in young; it is blackish and bears the lowermost 8 or 9 cirri, and ex- 

 tends ventrally to about upper edge of pupil; snout profile nearly 

 vertical; edge of upper lip with numerous short papillae or crenulate 

 in young; lower lip with mesial third smooth, lateral third on each 

 side somewhat plicate; no cirri on chin; lateral line arched over pec- 

 toral fin then curving to midlengthwise axis of body, ending at caudal 

 fin base; vertical line through dorsal origin passes just behind ventral 

 tip of nuchal fringe base and just behind pelvic bases; pectoral fin 

 reaches a little past anal origin; anal spines 2, first embedded on fe- 

 males past the Ophioblennius stage, both free on males; adult males 

 have crenulate and convoluted spongy masses on these spines; a
