occipital scute is dark brown; a squarish dark blotch surrounds a 

 small light median patch between the ends of the occipital ridges. 

 The character of the highly variegated markings is similar in the 

 two specimens, and is sufficiently well shown in the figure. The pos- 

 terior portion of the tail is marked by a series of dorsal and anal 

 blotches, extending from the fin bases almost to the lateral line. 

 The first dorsal and pectoral fins are light dusky; the second dorsal 

 and the anal are light except near their anterior ends; the ventral 

 fin is dark, with a white filament. The buccal cavity is lined with 

 dusky except near the gape ; the upper walls of the branchial cavity 

 are brownish black; the opercular and branchiostegal membranes 

 are bordered along their free edge by a light streak; the parietal 

 peritoneum is purplish brown underlain with silvery.

C. cingulatus is a specie's not closely related to others found in the 

 same or adjoining waters. It is probably most closely related to inno- 

 tabilis, an Australian species with which it is compared in the pre- 

 ceding key to the species of the genus. It also bears some resemblance 

 to gladius, an Hawaiian species.
