Color in spirits pale-brown, a little darker above; a dark-brown 

 vertical band through the eye, equal to its width, and margined with 

 white narrowly in front; 7 or 8 narrow, oblique, dark stripes sloping- 

 forward from the base of the dorsal till they meet on the sides; a 

 series of 10 similar l)ands obliquely sloping in the reverse direction: 

 edge of soft dorsal with a narrow dark-brown margin, below which 

 and adjoining is a narrow white stripe; a large blackish-brown ocellus 

 nearly as large as the eye in the upper corner of the soft dorsal 

 behind the elongated rays; margin of soft anal pale with a narrow 

 white line, above and adjoining is a narrow dark-))rown line; about 

 the middle of the caudal is a ])road white bar, narrowl}' edged with 

 brown. Here described from specimens from OkinaAva, Riukiu. 

 Leng-th 4 inches. 



This species is verv abundant throughout the tropical Pacific Ocean 

 from the Red Sea to the Hawaiian Islands. We have received 2 speci- 

 mens from Nafa, in Okinawa, from Yonekichi Koneyama. 



Bleeker identities Chaitodon setifer' with Chsetodon auriija without 

 raising any question. But in Chxtodon aurlga the black dorsal mark- 

 ing is not a spot, as in setifer^ but becomes an "oblique cuniform 

 blackish ])and from the origin of the soft dorsal to the ])osterior part 

 of the anal."" This certainly indicates specific distinction. Chs&todon 

 nesogalUeiis^ also included by Bleeker under Oh. auriga^ has a broad 

 band across the tail, the soft dorsal and the anal, with a white ring on 

 the dorsal part. This is probably the 3'oung of aurlga. The figures 

 of Bleeker and Day represent Chsetodon setifei\ not Chsetodon aurlga. 

 Cuvier and Valenciennes describe Chsetodon aurlga as "a Chsetodon 

 setlfer without ocellus on the dorsal," a difference which is probably 

 valid for distinction.
