pectoral counting the splint above; no black 
dot on the caudal peduncle above. 
This species will be described elsewhere by 
Dr. L. P. Schultz. 
*Pseudocheilinus hexataenia (Bleeker) 
Fowler and Ball, 1925, 6 specs. This record 
undoubtedly refers to either Pseudocheilinus sp. 
or P. octotaenia. 
Pseudocheilinus octotaenia (Jenkins) 
2 specs., 73 and 85 mm., 1951; 1 spec., 76 
mm., Brock, 1948. 
First dorsal rays not longer than those of 
the middle of the fin; three longitudinal rows 
of scales on cheek below eye; six to eight 
black longitudinal lines on sides, the lower- 
most well below the middle of the body; 14 
rays in the pectoral fin counting the splint- 
like ray above. 
Stethojulis axillaris (Quoy and Gaimard) 
17 specs., 30-71 mm., 1951; 1 spec., 82 
mm., Brock, 1948. 
One or more black dots along the middle 
of the caudal peduncle. 
Thalassoma ballieui (Vaillant and Sauvage) 
Fowler and Ball, 1925, 1 spec. As Julis 
verticalis Smith and Swain, 1882, 1 spec. 
Fowler and Ball’s specimen has been re- 
examined. Though in poor condition, it does 
show the concentration of vertical markings 
on the scales on the caudal peduncle. 
Thalassoma duperrey (Quoy and Gaimard) 
16 specs., 55-162 mm., 1951; 1 spec., 146 
mm., Brock, 1948. Halstead and Bunker, 
1954, 1 spec. As Julis clepsydralis Smith and 
Swain, 1882, 1 spec. 
A distinct light brown cross band through 
shoulder region in life, the fish becoming 
plain dark in preservative without marks ex- 
cept often for a dark mark on the upper edge 
of the pectoral base. 
Thalassoma lutescens (Lay and Bennett) 
5 specs., 53-116 mm., 1951. As Thalassoma 
aneitense , Fowler and Ball, 1925, 1 spec. 
This species, of greenish yellow coloration 
in life, agrees well with Jordan and Ever- 
mann’s plate (1905, pi. 41, as T. aneitense ) 
except that each scale has an indistinct ver- 
tical stripe. However, there seems to be no 
way besides color by which to distinguish 
these specimens from T. duperrey , and it 
might prove difficult to refute the view that 
they simply represent a color variant of T. 
duperrey (similar to the yellow phase of Epi- 
bulus insidiator). The absence of canine teeth 
given by Jordan and Evermann {op. cit .) is 
valueless. Johnston specimens of T. lutescens 
have canine teeth exactly as in T. duperrey. 
Thalassoma purpureum (Forskal) 
Fowler and Ball, 1925, 1 spec. 
This specimen has been reexamined. It has 
the broad band, branching below, extending
