Precision measurements were made on the 3 specimens from the 

 East Pacific and are expressed in thousandths of the standard length, 

 respectively. Standard lengths 275, 465, and 460. Length of head 

 360, 367, and 370; greatest depth 342, 410, and 370; length of snout 

 146, 177, and 176; diameter of eye 58, 43, and 41; fleshy interorbital 

 space 131, 129, and 135; postorbital length of head 171, 183, and 

 182; least preorbital width 73, 85, and 91; least depth of caudal 

 peduncle 138, 149, and 145; length of caudal peduncle 167, 184, and 

 165. Length of longest dorsal spine 127, 116, and 117; of soft dorsal 

 ray 124, 131, and 137; of anal spine 135, 99, and 117; of soft anal ray 

 145, 114, and 119; of pectoral 244, 228, and 229; of pelvic 193, 205, 

 and 187; of caudal fin 320, 485, and 327. 



The lips do not cover the green teeth, the angle between them 

 varies from 34 to 50 degrees; the inner hp is joined to upper Up much 

 closer to snout tip than to corner of mouth; two canine teeth at rear 

 corner of upper jaw; distal margin of caudal fin deeply concave. 



Background coloration of specimens preserved in alcohol brownish, 

 darker dorsally, paler ventrally. The details of color pattern are 

 illustrated in figure 2 (p. 19) ; the green marks are represented by 

 black shading. 



The Soccoro Island specimen, which is a mature male, had the 

 following color pattern when alive (based on a Kodachrome taken by 

 Richard Rosenblatt, University of California at Los Angeles) : 

 Edge of upper lip light orange, snout green, shading into dark brown 

 posteriorly; edge of lower lip green, then an orange crossband, followed 

 by an irregularly shaped green crossband; posterior to the latter on 

 under side of head light orange; ventral part of pectoral fin pale, 

 dorsally brownish green; outer margin of pelvic fin broadly green, 

 inner half pale; distal half of anal fin green, basal half light orange; 

 distal edge of dorsal with a narrow green band, basal % orange pos- 

 teriorly, brown anteriorly; outer margin of caudal green, then sub- 

 marginally pale, center rays of caudal green, except distal tips pale 

 and basally pale. Dorsal part of body greenish with a reddish brown 

 tinge anteriorly; side of body light orange, tinged with green ventrally. 



At first I considered the specimens from the Eastern Pacific to 

 represent a distinct species closely related to S. jordani but further 

 study of a specimen caught by Richard Rosenblatt in full color indi- 

 cates sexual dichromatism. The mature females are reddish brown, 

 whereas the mature males predominate in greens. 



The coloration of the Roqueta Island specimen was described as 

 follows by Carl L, Hubbs in his field notebook: "Largely blue-green, 

 becoming pale rosy brown on opercles, and on midsides. Teeth green. 

 Edge of upper lip orange-yeUow; snout deep blue-green above this 

 border. Lower lip has a narrow blue border and then a broad band
