THE FISHES OF EASTER ISLAND 63 
4. Holocentrus punctatissimus Cuv., Val. — KENDALL and RAp- 
CLIFFE |. c. p. 94. 
Three specimens, 48—-53 mm (s. c.). 
5. Kuhlia nutabunda Kendall and Radcliffe 1. c. p. 105, pl. III, f. 1; 
K. mutabunda REGAN |. c. p. 369, pl. LVI and Proc. Zool. Soc., 1913, p. 381; 
FUENTES 1. c. p. 13, lam. IV. 
Nine specimens, caught in pools on the shore; g2, 40—23 mm (s. c.). 
REGAN (I. c. p. 375 and 381) points out, that the base of the anal fin 
is decidedly shorter in this species than in the allied K. sandvicenszs Steind. 
In my largest specimen the anal is 0,7 length of head, thus agreeing with 
REGAN’'s statements. 
A matter of interest is that the young fishes, as to the coloration of 
the fins, show very great resemblance to the young XK. sandvicensis as described 
by JORDAN and EVERMANN (Bull. U. S. Fish Comm. XXIII, 1903, p. 208). 
The soft dorsal has an intermarginal bar of dusky, and the caudal is margined 
with dusky all round, the rest of the fin being white. 
6. Acanthistius fuscus Regan l. c. p. 368, pl. LV; FUENTES, I. c. p. 
13, lam. III; A. cewctus KENDALL and RADCLIFFE l. c. p. 107. 
Native name: Copoco mangara. — Two specimens, 186 and 176,; mm 
fs) c.) 
REGAN based his description of A. fuscus on a single specimen, 230 mm 
total length. The present two specimens show that several of the characters 
stated by REGAN as distinguishing this species from the nearly allied A. czctus 
Giinth. fall within the limits of individual variation, so that the resemblance 
to the latter is much greater than indicated by the type specimen, which is 
illustrated by the table below.

The two species can, however, be separated from each other at a glance 
on account of the quite different coloration. 
7. Trachypoma macracanthus Giinth. — T. macracanthum, KENDALL 
and RADCLIFFE |. c. p. 107. 
Native name: Copoco kava. — One specimen, 167,5 mm (s. c.). 
The proportions of the present specimen are: Height 2 %/, in length 
without caudal; head 21/s in the same; snout 4,4 in head and 0,88 diameters
