192 " ENDEAVOUR " SCIEKTIFIC RESULTS. 



margin close to the profile, its upper part beset with spinules 

 which are most numerous in the larger specimen ; inter- 

 orbital space almost flat. Preoperculum finely serrate on both 

 the hinder and lower margins. Opercular membranes united 

 across the throat, those of the branchiostegals broadly at- 

 tached to the isthmus. 



Scales largest on the middle of the sides, and arranged in 

 obhque rows above the lateral hne, which become more hori- 

 zontal below. They commence before the nostrils and extend 

 over the preorbital, opercles and throat, leaving only the end 

 of the snout bare. Lateral fine forming a liigh arch, and 

 extending to the hypural joint ; it is formed of about forty- 

 seven tubules. There are about forty rows of scales between 

 the scapula and the hypural joint ; six between the base of 

 the last dorsal spine and the lateral hne, and twenty-two more 

 to the first anal spine. 



Dorsal spines strong, increasing in length backwards ; the 

 last is shghtly longer than the head, and but httle shorter than 

 the longest rays. The soft dorsal is evenly rounded, with the 

 hinder margin subvertical when the rays are laid back. Anal 

 similar to the dorsal. Caudal subtruncate. Ventrals reaching 

 the second or third anal spine. 



Colour- -Ground colour whitish in formahne, probably yeUow 

 in Ufe. A broad ocular band extends from the nuchal region 

 through the eye, to the isthmus. A second band commences 

 bslow^ the anterior dorsal spines and crosses the end of the 

 operculum and base of the pectoral fin, to the ventrals ; it is 

 united below w ith another band extending from the bases of 

 the posterior dorsal spines to the belly. A less definite and 

 broader grey band crosses the body betw^een the middle of 

 the soft dorsal and anal, and extends onto the bases of those 

 fins. A broad blackish band encircles the base of the tail, and 

 has its posterior margin angular with the apex directed back- 

 ward. The membrane between the second and third dorsal 

 spines is black. Soft dorsal and anal fins with tw'o intra- 

 marginal, narrow, dark fines, separated by a white interspace, 

 and wdth broad, fighter borders. The anterior portion of the 

 soft dorsal within the dark fines is dusky, and the smaller 

 specimen has a large oceUus between the eleventh and seven- 

 teenth rays. Ventrals black. 



Described from two specimens 107-135 mm. long, the larger 

 of which is figured, and is selected as the type. They are 

 closely alfied to C. chrysozonus,. Cuvier & Valenciennes, but 

 differ in having a shorter spinous dorsal, with only eight 

 spines, and longer and more numerous rays.
