1078. Callyodon gilberti (Jenkins). Hawaii; Laysan. 



fScarus hataviensis, Steindachner, Denk. Ak. Wiss. Wien, lxx, 1900, 508, Honolulu, Laysan. 

 Scarus gilberti Jenkins, Bull. U. S. Fish Comm., 1899 (1900), 59, fig. 17, Honolulu. 



This scaroid is rather rare at Honolulu. It is close to C. bataiiiensis, but apparently distinct. 



1079. Callyodon abacurus Jordan & Seale, new species. Fuga meamea. Samoa. (PI. xxxin.) 

 Head 2.85 in length; depth 2.90; eye 8.50 in head; snout 2.20; interorbital 3; dorsal ix, 10; anal 



in, 9; scales 2-26-6, two rows on cheek, the lower preopercle limb bare. 



Body oblong, compressed, the anterior profile bluntly rounded, the snout slightly gibbous; 

 two large posterior canines on upper jaw, none on lower; upper lip broad, covering two-thirds or 

 more of upper jaw; lower lip narrow, covering less than half of jaw; depth of caudal peduncle 2.45 in 

 head; longest ray of dorsal 3; base of anal 1.30, 2.10 in base of dorsal; pectoral 1.35 in head; ventral 

 2; caudal slightly lunate. 



Color in life of a specimen from Apia, bright green, the tail bright blue, a golden shade before it; 

 belly creamy yellow; a dark shade behind pectoral; scales with broad brown bar which becomes an 

 orange spot on posterior parts; cheeks green; forehead purplish olive; lips orange, yellow-edged, with 

 a bright blue stripe across each, these meeting, running through the eye and sending a blue stripe to 

 angle of mouth; the blue stripe green behind with an orange stripe below it; opercle edged with orange, 

 preceded by a green stripe, a brown blotch above; dorsal bright blue with a continuous median stripe 

 of golden; caudal (slightly lunate) bright blue, with golden bronze stripe on each lobe and cross spots 

 and vermiculations at base; ventral golden with bright blue anterior edge; pectoral black, golden 

 washed, and edged in front with blue. 



A larger example is rather golden than green, the dusky purplish area above pectoral more 

 marked, the dorsal and caudal with marks of purplish brown rather than orange; eye blue above a 

 green streak before it. In all specimens the blue caudal peduncle has a large golden spot on each 

 scale, giving a checkered appearance. 



A specimen from Pago Pago was colored as follows: Upper and under lips, bars on under side of 

 head, ventrals except a pinkish salmon median blotch, margin of dorsal and anal, and median longitu- 

 dinal ventral line, all light blue; darker blue suborbital line from upper lip; postorbital blotches dark 

 green next eye, lighter green farther back; top of head smoky olive green, farther back lighter green; 

 body anteriorly yellowish-reddish-greenish with pinkish yellow coloration on sides of head and 

 almost yellow on underside of head and bordering median ventral blue line; body posteriorly bluish- 

 green with pinkish-yellowish-brown markings or checkers, one on each scale; portions of dorsal, anal, 

 and caudal which are not blue, yellowish salmon. 



Color in spirits, dull yellowish; caudal peduncle green with three longitudinal rows of round yel- 

 low spots; a broad dusky band occupying all the nuchal region to base of third dorsal spine, this band 

 extending obliquely down and back on the side to a line with base of anal fin and lower margin of 

 pectoral; margin of lips yellow; top of head and snout purplish; a green line with dark margins at 

 upper margin of orbit, another short one at posterior margin of orbit, and a third from opercle along 

 lower part of orbit down side of snout around upper lip, a branch descending to axil, and another 

 branch around lower jaw posterior to yellow margin; dorsal fin yellowish white, the margin and base 

 each with a band of green; anal colored similar to dorsal except the distal blue band is broader; pec- 

 toral dark purplish; ventral yellowish with a slight trace of bluish margins; caudal green with some 

 scattered round yellowish spots, the middle portion of fin lighter; iris golden; teeth green. 



We have 13 specimens of this beautiful species from the coral reef at Apia and 2 from Pago 

 Pago. The type is no. 51754, V. S. National Museum, 12.75 inches long, from Pago Pago. 



1080. Callyodon lauia Jordan & Evermann. Hawaii. 

 This may be the same as Callyodon formosus. 



1081. Callyodon formosus (Cuvier & Valenciennes). Hawaii. 



Scarus formosus Cuvier & Valenciennes, Hist. Nat. Poiss., xiv, 283, 1839, Sandwich Is. 



The description of Callyodon formosus seems to apply fairly well to Callyodon lauia. Callyodon 

 jenkinsi is also closely related. 



1082. Callyodon dimidiatus (Bleeker). Papua; Shortland I. (Seale). 

 Scarus dimidiatus Bleeker, New Guinea, 17, Papua.
