teeth of upper jaw on outer edge of dental plate, alternating, in 2 series for about half length of jaw, 

 where they are followed by a single strong curved canine which projects outward and backward; 

 below and posterior to the canine the dental plate bears on its surface a row of small blunt teeth ; 

 lower jaw with 3 rows of teeth anteriorly, 2 laterally, and 1 posteriorly, all on outer edge of dental 

 plate, whirl] has a rather rough flat surface within the rows of teeth; dorsal spines stiff and sharp, the 

 first i I mgesl ) contained about 2.5 times in head, rays somewhat shorter, there being but little differ- 

 ence in the height between the spinous and soft dorsals; anal spines 3, small and slender, the soft rays 

 nearly equal in height, 2.6 in head; dorsal and anal extending an equal distance posteriorly; ventral 

 rounded, 1.7 in head; pectoral 1.5 in head; upper lobe of caudal slightly concave, the lower rounded, 

 the middle and upper rays longest, basal portion of tin with large scales; lateral line following contour 

 of back to a point below posterior end of dorsal, where it is abruptly bent downward, passing along 

 middle of caudal peduncle; scales on occiput and on opercles, a single row passing obliquely downward 

 on cheek below eye; a scries of ± scales anterior to origin of dorsal fin. 



Color dusky, indistinctly mottled with lighter and darker shades; a broad diffuse hand of bright 

 brassy yellow, extending obliquely across the side from between the third and seventh dorsal spines

to the anterior end of base of anal; dorsal mottled with blackish; other tins dusky; base of pectoral 

 and chin blackish. 



The type no. 57786, U. S. National Museum, from the market at Honolulu, measures 11.5 inches 

 in length. Another specimen 13.5 inches long, does notdiffer from the type, except that the teeth are 

 somewhat worn, the canines being broken off; the yellow cross-band is less distinct. 



25. Callyodon perspicillatus (Steindachner). (PI. xm, fig. 2.) 



We present a colored plate of this handsome species, taken from a fresh specimen, in which, 

 however, certain evanescent shades, as of golden on the opercular flap and rosy on the base of the 

 dorsal, had faded. 



Family CH/ETODONTID^E. 



26. Chaetodon ephippium (Bloch). 



A cast of this most handsome species, which is rather common in the South Seas, is in the Bishop 

 Museum. The specimen came from Honolulu, and this is the first Hawaiian record. 



Probably the name Zanclvs cornvtus should be retained for the common species of Zanciu*, as /. 

 canescenx is probably a distinct species.
