Canine teeth in jaws small, not markedly longer than inner villiform 

 teeth, and nearly uniform in size; palatine teeth absent; free margin 

 of preopercle serrate, the serrations on upper limb coarse; curved hind 

 margin of preorbital free for about one-fourth the distance from lower 

 edge to eye; interorbital not scaled; 3 rows of large scales on cheek 

 with a few forming an incipient fourth row; depth of body 4.4 to 4.6 in 

 standard length (Bohlke and Briggs, 1953, p. 375, reported the depth 

 of seftoni as 4.2; however their figm-e shows a depth of about 4.4 in 

 standard length) ; snout very elongate, its length about 2 in head length ; 

 dorsal profile of head slightly concave; 2 to 4 cirri from membrane near 

 tip of each dorsal spine (1 or none from last 2 spines); membranes 

 between dorsal spines deeply incised, the one between the fifth and 

 sixth spines notched nearly half the length of these spines; fourth dor- 

 sal spine the longest, its length 1.28 to 1.46 in body depth; first dorsal 

 soft ray not produced into a filament; pectoral fin length variable, the 

 tips of longest rays not reaching pelvic tips in Indo-Malayan form but 

 extending to or beyond origin of anal fin in eastern Pacific form; 

 longest branched pectoral ray contained 1.2 to 1.35 in length of longest 

 unbranched pectoral ray; tips of pelvic fins reach slightly posterior to 

 anus; caudal fin emarginate. 



Color in alcohol pale, some specimens retaining 9 bars which slant 

 diagonally posteriorly as they pass downward on the body, and 4 

 lengthwise dark bands, resulting in a cross-hatching effect on the body. 

 The dark marldngs are red in life and the ground color whitish. Two 

 lengthwise dark bands in dorsal fin. 



Kemarks. — Known in the literature from 4 specimens: the type 

 from Amboina, a specimen from Mauritius (Giinther, 1860, p. 76), the 

 type of mormi from the Philippines, and the type oisejtoni from Baja 

 California. The holotype of tyjpus is in the Rijksmuseum van Natu- 

 urlijke Historic at Leiden (No. 5846). M. Boeseman kindly supplied 

 the following information on the specimen: standard length 84 mm., 

 total length 100 mm., depth of body 19 mm., head length 36 mm., 

 snout length 18.9 mm., postorbital part of head 11.2 mm., diameter of 

 eye 6 mm., length of longest unbranched pectoral ray 18 mm., length 

 of longest branched pectoral ray 15 mm., length of third dorsal spine 

 12.2 mm., length of fourth dorsal spine 13 mm., length of tenth dorsal 

 spine 10.1 mm., length of second anal spine 13.7 mm., length of pelvic 

 spine 9 mm., caudal indentation 4.5 mm., indentation of membrane 

 between fifth and sixth dorsal spines 5.4 mm., number of serrations on 

 preopercular margin 23 (20); number of pectoral rays (both sides)

The type of 0. morrisi Fowler (USNM) measures 72 mm. in standard 

 length, and it is uniformly pale (probably faded). In his description of
