ART. 33. NOTES ON" FISHES OF HAWAII E. K. JORDAN 36 



PSEUDOSCARUS HELIOTROPINUS Bryan. 



This species, known only from a single specimen and a painted 

 cast in the Bishop Museum, is extremely close to the East Indian 

 P. xantho'pleum (Blecker), differing only in certain details of color. 



Below I quote Bryan's original description of Pseudoscanis helio- 

 troplnus from the Director's report of the Bishop Museum for 1905 

 (p. 23, fig. 3). This paper, in which a number of Hawaiian Scari 

 are described, three of them new, is little known. 



Head 3.2 in body; depth 3.1; eye 8 in head; interorbital 2.6; D. IX, 9; 

 A. II, 9 ; P. 14 ; scales 2-25-7. 



Body very stout; head deeper than long; snout blunt, the dorsal outline 

 strongly convex, the anterior profile rising almost vertically from the lips; 

 teeth blue ; upper jaw with one or two blunt canines ; depth of caudal peduncle 

 2 in head ; scales deeper than long ; two rows of large scales on the cheek, 

 one row on the subopercle ; lateral line interrupted under the last dorsal ray, 

 but continued on the second row below ; pores with two or three irregular 

 branches ; anal and dorsal about equal in height ; caudal deeply lunate, the 

 outer rays extending beyond center rays twice the length of latter; ventral 

 J .8 in head, falling short of anal by 0.6 their length ; pectoral broad, 1.2 in 

 head. 



Color in formalin -j- alcohol. General color, grayish brown ; brownish over 

 the snout ; an indistinct greenish patch on the cheek and lower lip ; ventral 

 margined and tipped with greenish, remaining portion pale; dorsal with a 

 greenish base and margin ; caudal like the body, but with outer streamers and 

 two or three ill-defined spots greenish ; base and outer third of the anal 

 greenish, portion between pale; pectoral pale, with an indication of green. 

 Teeth blue. 



Color (based on plaster cast colored from life). General color of lower 

 half of body, pale salmon, varied with bluish scale markings; dorsal anterior 

 half of body back to tip of pectoral heliotrope brown ; remainder of dorsal 

 portion as well as caudal peduncle pure green, varied with pinkish scale 

 markings ; interorbital region greenish brown ; upper lip green, edged with 

 orange-ochraceous ; an ill-defined brown stripe over the middle of the snout; a 

 broad orange-ochraceous patch on the lower lip, which is bordered above and 

 below with blue, the latter color joining at the angle of the mouth, becoming a 

 greenish blue patch on the cheek which is crescent-shaped on its posterior 

 outline, one point of the crescent reaching to the eye ; greenish stripes radiat- 

 ing from the eye, narrow greenish stripe connecting the points of the crescent 

 on the cheek ; scales on the cheek greenish ; chin flesh color, with a few irregu- 

 lar blue spots; dorsal edged with blue; blue marks along the bases of the 

 third to sixth spine ; remaining rays with serrate green ray marks ; re- 

 mainder of the fin salmon color ; anal broadly margined with blue ; blue mem- 

 brane spots at base, forming an irregular line; remaining portion salmon- 

 pink ; caudal with the outer rays blue passing into green, the green extending 

 over most of the elongated rays ; inner edge of the elongated rays and central 

 portion of the tail ochraceous-salmon ; four large irregular green blotches on 

 the middle rays arranged so as to form a subterminal bar, with its posterior 

 edge one-fourth of the length of the middle rays from the margin of the 

 caudal ; a few blue spots between the blotches and the base of caudal ; ventrals 

 salmon color, the outer ray for its entire length, the second for its distal half 

 blue ; pectoral green ; iris yellow. 



The type (B. P. B. Museum No. 3363) here described was secured in Hono- 

 lulu market February 8, 1903, and measures 22 inches.
