FAMILY POMACENTRIDAE — WOODS AND SCHULTZ 91 



Depth of body 2.2 to 2.4; head 3.2 to 3.4; both in standard length. 

 Snout 3.8 to 4.1; eye 3.2 to 3.3; preorbital width 9.1 to 11.3; length 

 of upper jaw 3.3 to 3.4, postorbital part of head (hind margin of eye 

 to upper edge of gill opening) 2.4 to 2.6; interorbital width 3.6 to 4.5; 

 depth of caudal peduncle 1.9 to 2.2; length of pectoral fin 1.2 to 1.3, 

 of pelvic fin 0.9 to 1.0, of 13th dorsal spine 1.8 to 2.0, of upper caudal 

 rays 0.9 to 1.0, of lower caudal rays 1.0 to 1.1; all in length of head 

 (tip of snout to hind margin of opercular membrane). Depth of 

 caudal peduncle in its length 1.1 to 1.3; angle of snout profile with 

 lengthwise axis of body 63 to 66 degrees, snout profile slightly concave 

 in large examples but upper profile strongly convex. 



Teeth of jaws crowded, long, slender, curved, basally cylindrical, 

 tips flattened and rounded, in two rows, teeth of inner row slightly 

 smaller and fitting between teeth of outer row near tips; scales of 

 interorbital region not extending as far forward as nostrils; snout and 

 preorbital naked; suborbital naked, both margins of preopercle naked; 

 opercular spines 2, the ventral one largest, both flat, triangular; dorsal 

 spines subequal after 3rd, soft dorsal and anal outlines angular, caudal 

 lobes rounded, pectoral rounded. 



Color in alcohol. — Light reddish brown to dark grayish brown or 

 black; opercle pale, membrane black between spines, dusky below 

 spines; body with 3 pale transverse diagonal bars, the first from upper 

 posterior edge of opercle behind pectoral axil to near pelvic insertion, 

 the second from below 5th to 7th dorsal spines to anus, the third 

 across caudal peduncle just behind last soft dorsal rays, the second 

 and third bars may be indistinct or absent and the body uniformly 

 black, except area behind pectoral usually pale; very dark brown or 

 black bar across pectoral base; spiny dorsal membrane brownish with 

 black submarginal line and tips of membranes pale, soft dorsal basally 

 dark brown or black and distal half of soft rays pale; anal entirely 

 dark brown or black; posterior part of caudal peduncle and base of 

 caudal fin intense black (in young the black is confined to upper part, 

 the remainder being merely dusky) rest of caudal fin pale, except that 

 some specimens have outer edges of upper and lower rays dusky and 

 tips of median rays dusky, pelvics dark brown or black, pectorals pale. 



Remarks.— Ovily very few specimens from the Marshalls bore the 

 middle transverse bar, several had the anterior part of the caudal 

 peduncle pale ; all possessed the pale opercle and light area behind the 

 pectoral; in our numerous examples from the Marianas the ratio was 

 reversed, nearly all specimens having the 3 transverse bars and only 

 a few being uniformly dark colored; when all specimens were carefully 

 compared, intermediate color patterns were observed.
