THE FISHES OF EASTER ISLAND

4. Holocentrus punctatissimus Cuv., Val. 



CLIFFE 1. C. p. 94. 



Three specimens, 48 — 53 mm (s. c).

5. Kuhlia nutabunda Kendall and Radclifife 1. c. p. 105, pi. Ill, f. 1; 

 K. niutabiinda Regan 1. c. p. 369, pi. LVI and Proc. Zool. Soc, 1913, p. 381; 

 FUENTES 1. c. p. 13, lam. IV. 



Nine specimens, caught in pools on the shore; 92, 40 — 23 mm (s. c). 



Regan (1. 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. sandvicensis 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 K. 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 1. c. p. 368, pi. LV; Fuentes, 1. c. p. 

 13, lam. Ill; A. cinctus Kendall and Radcliffe 1. c. p. 107. 



Native name: Copoco mangara. — Two specimens, 186 and 176,5 mm 

 (s. 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. cinctus 

 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. Trachyponia macracanthus Giinth. — T. macracanthum, Kendall 

 and Radcliffe 1. 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 2^/4 in the same; snout 4,4 in head and 0,88 diameters
