Chaetodon collaris Bloch. 



Chsetodon collaris Day, Fishes of India, Atlas (1878), PI. 27, fig. 6; 

 Bleeker, Atlas Ichth. (1877), 9, PL 23, fig. 2; Gunther, Cat. 

 Fishes Brit. Mus. (1860), 2, 21; Jordan and Evermann, Proc. U. S. 

 Nat. Mus. (1903), 25, 356. 



This species, which is without doubt C. collaris of Day, of 

 Bleeker, and of Gunther, is characterized by the dark ventrals, 

 comparative narrow ocular band which does not extend to the 

 origin of the ventrals, and the color of caudal which is broadly 

 margined with white with a broad black bar near its center. 

 Chxto&on collaris Gunther 3 is possibly a variety of C. reticulatus 

 Cuvier and Valenciennes with the black ocular band extending 

 backward on the thorax to the origin of the ventrals ; it certainly 

 has but slight resemblance to Bloch's type of C. collaris. The 

 species described by Jordan and Evermann 4 is probably distinct 

 and should be described as such. 



Chsetodon modestus Temm. and Schleg. 



Chsetodon desmotes Jordan and Fowler, Proc. U. S. Nat. Mus. (1902), 

 25, 539. 



This species is related to C. rafflesii Bennett which is, however, 

 probably a valid species. (6293.) 



Chaetodon hella-maris Seale, sp. nov. Plate I, fig. 1. 



Head, 3.10 in length without caudal; depth, 1.45; eye, 3.15 in 

 head; snout slightly greater than diameter of eye; interorbital 

 space slightly greater than snout; dorsal, XII, 23; anal, III, 21; 

 lateral line strongly curved, ending at axil of soft dorsal, pores 

 46 ; scales in 34 series between head and end of caudal vertebra, 

 23 in a vertical series; head covered with fine scales; mouth 

 small; teeth setiform; gill rakers low and pointed, about 17 on 

 lower arch; spinous dorsal fitting into a scaled sheath at base, 

 the 4th, 5th, and 6th spines the longest; soft dorsal rounded, 

 no rays prolonged, length of longest ray but slightly less than 

 head; caudal 1.35 in head, its margin almost straight; anal 

 similar to soft dorsal ; ventrals equal to length of head without 

 opercular flap; a large axillary scale; pectorals equal to head 

 with opercular flap. 



Color in life yellowish, a black ocular band which is slightly 

 greater than width of eye above the eye and slightly less than 

 width of eye below; this band is continuous above, and extends 

 to margin of subopercular below the eye ; the band is margined
