figure ami in each of a large number of fresh and preserved examples the spots are on the upper parts 
alone, mostly anterior, and are in vertical rows on about every third row of scales; in some, intercalary, 
faint vertical rows appear between the dense black conspicuous ones, making a characteristic pattern. 
Common at Honolulu. I obtained nine examples, 3 to 4.S inches in length, and examined a large 
number of others.

167. Chaetodon fremblii Bennett. 
Life color, body bright yellow with 7 longitudinal light blue bands on side directed slightly upward, 
some of these extending on posterior portion of dorsal fin, second band interrupted; a bluish-black 
spot in front of dorsal; a black area on caudal peduncle extending up on posterior part of soft dorsal, this 
area with blue border anteriorly; dorsal bright yellow, with two longitudinal bands; caudal peduncle 
I black, base of caudal fin white, posterior to this a yellow crossband, posterior to this (the margin) white. 
Fairly common at Honolulu, where 8 examples, 3.6 to 5.75 inches in length, were obtained. 
Chsetodon fremblii Bennett, Zool. Jour., iv, 42, 1828 (Sandwich Islands); Gunther, Fische der Siidsee, Ii, 39, taf. xxrx, fig. B, 
1874 (Sandwich Islands): Steindachner, Denks. Ak. Wiss. Wien, ixx, 1900, 488 (Laysan). 
168. Chaetodon lunula (Lacepede). 
Color in life (field No. 149, 5 inches long), prevailing color yellow; black ocular band broader 
J than eye extending over head, including both eyes and reaching down on each side as far as lower 
edge of preopercle; front margin of this band bordered by a whitish line; immediately posterior to 
ocular band, not extending so far down as it, is a broad white band; space in front of ocular band to 
mouth yellow; tips of jaws red; a large black area on back including base of first 5 dorsal spines; a broad 
black band, lower portion as broad as length of caudal fin, extending from humeral region upward 
and backward to about origin of seventh and eighth dorsal spines, this black band bordered anteriorly 
and posteriorly by a bright orange yellow band; posterior and below this on the side and belly and 
breast, shading to olivaceous above, to bright yellow below; side with longitudinal narrow bands of 
orange, made by rows of orange dots, 1 on each scale; breast with orange dots; dorsal fin mostly 
j-ellow, with a narrow brown border, a yellow band running from body just in frontof caudal peduncle 
upward on to the dorsal and along it; a long black area on middle of posterior portion of soft dorsal; 
caudal peduncle black, the black extending on base of caudal posterior to this, caudal yellow for 
nearly half its area; posterior to this a dusky crossband, then yellow, then a'dusky band and most pos- 
teriorly white (the border); anal base and inner two-thirds yellow, outside of this a dusky longitudinal 
narrow band, then yellow, next this the brown border of the fin; ventrals bright yellow; pectoral 
transparent. This species varies much in the degrees of development of this pattern with age. 
Another specimen, young, 1.25 inches in length, gives the following coloration: Snout red; ocular 
band black, next to this a broad white band followed by a broad black one; body yellow, darker 
1 above, brighter below, black spot on caudal peduncle covering whole of peduncle; white crossband on 
base of caudal fin, posterior to this a narrow black line, behind this dusky; black spot on soft dorsal 
| surrounded by bright yellow line which behind becomes white. 
Quite common in the market. Nine specimens, 1.3 to 6.25 inches in length, were obtained.

Chsetodon lunula Cuvier & Valenciennes, Hist. Nat. Poiss., vn, 59, pi. 173, 1831; Gunther, Fische tier Siiilsee, tr, 42, taf.

Chsetodon tau-nigrum, Fowler, Proc. Ac. Nat. Sci. Phila. 1900, 513 (Sandwich Islands). 
169. Chaetodon sphenospilus Jenkins. 
Twelve specimens were obtained. In a large number of fresh examples seen by me since the 
description was published, each one shows the wedge-shaped dusky area projecting from the spot on 
the side; in some the point of the wedge-shaped area extends nearly to the ventral outline.
