tlescrijition of L. lunar is is not sufficiently full to enable us to settle this question with certainty. 
Jordan and Snyder expressly state that the head of their specimen was naked; ours has a patch of 
well-developed scales upon the upper limb of the opercle, which may indicate specific distinction. 
Moreover, we are able to find but 2 anal spines, a character in which it differs from other species of 
Thalassoma. >

239. Thalassoma aneitense (Gunther). Plate 41. 
Head 3.7 in length to base of caudal; depth 3.4; snout 2.8 in head; eye 5.3; interorbital space 4; 
scales 26-11; D. vm, 13; A. ir, 11. 
Teeth in both jaws growing gradually shorter from before backward; no enlarged teeth or 
canines; head smooth; scales smaller on breast and belly than on sides and back; lateral line extend- 
ing along fourth row of scales to below base of eleventh articulated ray, where it bends downward 
across 3 rows of scales and passes along middle of caudal -peduncle; first dorsal spine equal in length 
to about two-thirds diameter of orbit, the others successively longer, the last being 1.6 times diameter 
of orbit; articulated rays higher, about twice diameter of orbit; anal spines rather strong, the first 
equal in height to third dorsal spine, the second equal to last dorsal spine; dorsal and anal rays about 
equal in height; pectoral 1.4 in head; caudal probably truncate; ventral 2 in head. 
Color in spirits, pale brownish, the head dusky above; 2 dusky bars passing backward from eye, 
the lower of which extends toward angle of opercle; a broad semicircular bar extending from chin 
toward eye and bending downward toward lower edge of opercle; a smaller semicircular bar below 
the latter; scales with small white spots; distal half of pectoral blackish, the color fading out toward 
the lower edge; dorsal with a dark spot about the size of pupil on membrane of second and third 
spines. Known to us from the Hawaiian Islands by only one specimen, 5.2 inches long, obtained at 
Honolulu by Mr. Berndt.

Genus 157. JULIS Cuvier. 
This genus as here understood differs from Coris chiefly in the more elongate body and especially 
in the smaller scales, which are 75 to 95 in lateral series. In most species the anterior dorsal spines 
are slender and prolonged. Brilliantly colored fishes of the coral reefs, some of the species burying 
themselves in the sand. The name Julis, originally based on the Girelle of the Mediterranean (Julis 
julis), has been wrongly transferred to the genus Thalassoma by Bleeker and by Gunther.

a. First 2 dorsal spines longer than the others, the first 1.4 to 1.8 in head.

on side behind pectoral. 
c. Eye 8 in head; scales in lengthwise series 76; body color in life dark reddish brown; a deep green cross band from

cc. Eye 7 in head; scales in lengthwise series 82; body color in life brownish orange or cinnamon-brown, no deep green 
cross band from dorsal to vent: middle line of throat whitish; posterior violet spots larger than in gaimard

bb. Scales in lengthwise series 90 or more (92); posterior part of body without violet spots; about 8 blackish vertical 
crossbars on side behind pectoral lepomis, p. 306
