THE FISHES OF EASTER ISLAND 65 



One specimen, 115 mm (s. c). 



The coloration of the present specimen agrees with Kendall and Rad- 

 CLIFFE's figure pi. V, fig. 2 (1. c). The small, white (in spirits) spots on the 

 body sides are very distinct. 



11. Labrichthys semifasciatus n. sp. 



Two specimens, 222 (type) and 205 mm (s. c), bought in preserved state 

 on Easter Island. , 



D. XL it; a. JII. 10; P. 12; V. 1,5; scales in lateral line 26; 1. tr. ^/g. 

 Dorsal scales extending on the base of the fin. A posterior canine tooth. 

 Four anterior canine teeth in the lower jaw and two in the upper; cheek with 

 eight series of small scales. 



Proportions of the two specimens, 222 and 205 mm resp. Height 3,7 — 3,6 

 in total length with the caudal, 3,2 — 3,1 without that fin; head 3,5 in total 

 length c. c. and 3,0 — 2,8 s. c; eye in head 6,6 to a little more than 6 ^/s; 

 eye in snout 2,3 — 2,2; eye in interorbital space nearly 1,1; pectoral 1,7—1,6 in 

 head; height of caudal peduncle 6,6 — 6,7 in total length s. c. 



Caudal squarely truncate with the exception that the lower and especially 

 the upper lobes are produced and attenuated. 



Ground colour in spirits pale orange yellow, sides of head red (carmine?). 

 The upper parts of the head longitudinally striated with dark brown bands, 

 which also extend on the anterior back. The lowermost of these bands runs 

 from the upper lip, just touches the eye and ends with a dark semilunar spot 

 at the base of the opercular flap. The second stripe, counted from below, is 

 incomplete, only occupying the opercle and likewise ending in a dark spot at 

 the upper margin of the opercular flap. The number of bands is about 8 to 

 9 on each side of the head. The space occupied by the longitudinal stripes 

 is abruptly limited behind on the 3d — 4th vertical row of scales. Just at the 

 root of the caudal there is a broad, dark brown (purplish in life.'') cross-bar, 

 and between this and the striated area of the anterior back five triangular 

 cross-bars of similar colour. These cross-bars begin broadly above at the base 

 of the dorsal, except the hindmost, which joins with its fellow on the upper 

 side of the caudal peduncle. The hindmost bar does not quite reach the 

 lateral line with its tip, the second and third counted from behind reach two 

 scales below the lateral line, the fourth 3 — 4 and the fifth 4 — 6 scales below 

 the lateral line. 



The parts of the body next to the base of the dorsal and caudal fins 

 are probably red in lifetime. A narrow dusky line along upper and lower 

 margin of caudal as well as at the base of the pectoral. Membrane of dorsal 

 fin dark between 1st and 3d spines, otherwise the fins are pale orange yellow 

 as the body; very small scattered dark spots are to be seen on the dorsal in 

 the type specimen.
