Mus. No. 48871, a female specimen, 48 mm. 
in standard length, collected by J. Randall 
with a spear in the Moorea lagoon just east 
of Tareu pass at a depth of 8 feet on May 22, 
1956 (specimen was picking on the body of a 
female Scarus sordidus Forskal when speared) ; 
British Mus. No. 1956.8.14.1, a female speci- 
men with mature gonad, 45 mm. in standard 
length, collected with a spear by J. Randall 
within 75 feet of the locality of the May 22 
specimen at a depth of about 10 feet on 
March 29, 1956. 
Two more specimens collected by the au- 
thor, a male 46.5 mm. in standard length, 
from a depth of 7 feet in the Moorea lagoon 
near the entrance to Papetoai Bay on July 1, 
1956, and a 54.5 mm. female from 15 feet in 
the pass at Takaroa, Tuamotu Archipelago, 
Nov. 9, 1956, have been placed in the collec- 
tion of the University of Hawaii. Both speci- 
mens were speared, the former as it was pick- 
ing at the dorsal fin of Zebrasoma scopas 
(Cuvier). No external differences could be 
ascertained between the one male specimen 
and the female specimens. 
Some proportional measurements of the 
paratypes were difficult to make because of 
injury from spears. 
DESCRIPTION: Based on the holotype and 
the smallest (45 mm. in standard length, 55.3 
mm. in total length) and the largest (51 mm. 
in standard length, 62.5 mm. in total length) 
paratypes. Measurements are recorded for the 
holotype, followed in parentheses by data for 
the small and large paratypes, respectively. 
Meristic data are the same for the holotype 
and paratypes (with the possible exception of 
median predorsal scales which are obscure 
and difficult to count), hence only a single 
number is given for each count. 
Dorsal fin rays IX, 11; anal fin rays III, 10; 
pectoral fin rays 13 (the uppermost rudimen- 
tary, the next unbranched); pelvic fin rays 
I, 5; principal caudal rays 14. Lateral line 
scales 28, the last enlarged and bearing a 
prominent lateral line tube (scales extend 
posterior to lateral line nearly half the remain- 
ing length of caudal fin); scale rows above 
lateral line to base of first soft dorsal rays 3 
(the upper row extending on to base of dorsal 
fin); scale rows below lateral line to base of 
first anal soft rays 8 (two additional rows of 
moderately large scales on base of anal fin at 
this point); median predorsal scales 8 or 9; 
snout, chin, throat, and dorsal part of head 
naked. Gill rakers (including rudiments) on 
first gill arch of 48 mm. paratype 15. 
Head length 2.78 (2.67-2.77); depth of 
body 3.48 (3.50-3.69); snout to anus 1.66 
(1.70-1. 69); snout to origin of pelvic fins 2.70 
(2.59-2.66); snout to origin of dorsal fin 2.92 
(2.74-2.91); length of dorsal fin base 1.99 
(2.08-2.07); length of anal fin base 3.60 
(3.89-3.90) — all in standard length. 
Width of body at gill opening 2.70 (2.81- 
2.75); least depth of caudal peduncle 2.16 
(2.33-2.32); snout length 2.85 (2.91-2.87); 
diameter of eye 5.11 (4.82-4.98); width of 
interorbital 3.81 (4.02-3.88); length of pec- 
toral fin 1.50 (1.53 and 1.53); length of pelvic 
fin 1.96 (1.96-1.94)' — all in head length. 
First dorsal spine 8.64 (9.62-9.20) in head 
length; dorsal spines progressively longer 
(filaments of interspinous membranes extend 
beyond spine tips), the ninth 3.40 (3.75-3.58) 
in head length; first dorsal soft ray 2.43 (2.42- 
2.52) in head length; first anal spine nearly 
half as long as second; second anal spine 
about two-thirds as long as third; third anal 
spine 3.63 (3.47-3.57) in head length; first 
anal soft ray 2.18 (2.00-2.11) in head length. 
Caudal fin slightly rounded. 
Width of mouth (rictus to rictus) equal to 
eye diameter. Center of upper lip to rictus 
about 5 in length of head. Distance between 
lobes of lower lip about one-third diameter 
of eye. 
A pair of curved canine teeth (the uppers 
more curved than the lowers) anteriorly in 
each jaw, about one-fourth eye diameter in 
length. Upper canines fit inside lowers when 
jaws are closed (upper and lower canines on 
one side separated by a distance slightly less 
than diameter of base of one of the teeth) . A
