170. Chsetodon trifasciatus Park. 
Color in life (field No. 183, 5.75 inches in length), general color of sides of body orange, with 
numerous longitudinal lines of dark brown, those above the middle line of body slightly convex 
toward dorsal line, those below slightly convex toward ventral outline; ocular band black, narrower 
than eye, with narrow bright yellow borders, the band continuous around the head above and below; 
in front of ocular band is a bright yellow band, continuous above and below; tips of jaws black; 
behind ocular band is a bright yellow band, adjoining this a narrow black band; the opercle and pre- 
opercle behind this are yellow; an orange patch on middle line of body just in front of origin of spinous 
dorsal; breast yellow; anterior portion of spinous dorsal orange with light green border; beginning on 
the body parallel with base of soft dorsal fin and including the whole of the fin are 7 bands of color; 
first (innermost) yellow; next black, wedge-shaped, broadest end on caudal peduncle, narrow end 
on posterior portion of spinous dorsal; third band bright yellow, fourth yellow, fifth dusky; sixth 
yellowish-green, on posterior portion round dots of orange; seventh reddish-brown (the outer) ; caudal 
base (except black of above-mentioned band) light with violet tinge, exterior to this a series of cross- 
hands; the first aboutthe middle, a narrow orange; next a broader black; next a narrow bright yellow; 
and the next, the outermost, a broader white; just above anal on body parallel to base a yellow band, 
exterior to this and on base of fin also a black band, then (on soft portion) next a narrow orange, 
then a broad, brownish-red band; last (the extreme border of soft anal) a narrow bright yellow; 
area covering the first 2 anal spines a bright reddish-orange; ventrals bright yellow; base of pectoral 
bright orange, fin transparent. 
Two specimens of this most beautifully marked species, 5.6 and 5.75 inches in length, were taken 
by me in 1889; and one, 4.8 inches long, by the Albatross in 1896 at Honolulu, where it does not seem 
to be common. This seems to be the first record of this species from the Hawaiian Islands.

171. Chaetodon quadrimaculatus Gray. 
Color in life (field No. 293), the upper half of side of body dark brown, almost black; lower 
half orange, with each scale with a brown spot; 2 white areas on the upper brown portion; ocular band 
wide as eye, dark brown above eye, orange below, bordered on both sides through its whole length 
by white borders; before and behind ocular band on head orange; tip of snout brown; base of dorsal 
dark brown, the brown extending about half its height on soft dorsal; a white longitudinal band above 
this on soft dorsal, extending a distance on to the spinous dorsal; this band is bordered above by a 
narrow line of dark brow-n, above this the fin is orange, with a very narrow- outer margin of dark 
brown, outer portion of spinous dorsal orange; caudal peduncle orange; dark-brown crossband at base 
of caudal fin, the fin a bright orange, with narrow posterior border of white; inner portion of anal 
bright orange, a curved white band, convex outwardly, extending on it from base of first spine to near 
posterior outer angle of soft portion; bordering this band exteriorly a narrow brown band; exterior to 
this both spinous and soft portions are bright orange; ventrals bright orange; pectoral transparent. 
This is a very common form about the reefs at Honolulu. Nineteen examples were obtained, 3 to 
5 inches in length.
