spine, from whence it slopes gradually downwards to opposite the third or fourth dorsal ray, and 
then proceeds nearly straight to the centre of the caudal. 
The air bladder extends far backwards on each side of the haemal spines. 
Colours—Upper surface of head and back bluish grey, fading to silvery on the opercles and 
abdomen. A bluish grey spot on the upper portion of the opercle, and a series of from six to 
eight, or sometimes a double row, above the lateral hue. Pectoral and caudal yellowish, the last 
stained with black at its margin. Summit of the second dorsal blackish, the rest of the fins 
white. Iris silvery. 
Grows to twenty inches in length. 
Habitat—Eastern coast of Africa, Seas of India, Malaysia, and China.

Eyes—Their diameter equals their distance from the anterior extremity of the snout.

resemblance to that of the C. lysan. 
Teeth—Eesembling those of the C. tala, C. fy V. 
Lateral line—Scarcely curved.

Cleft of mouth rather small, muzzle swollen and very obtuse. Infraorbital bones do not articulate with 
the preopercle. Two dorsals, the first composed of free spines, with a small interspinous connecting 
membrane, and a horizontal procumbent spine directed forwards anterior to the fin, the base of which is of 
less extent than that of the soft dorsal or of the anal, the anterior margins of each of the latter fins are 
pointed and elongated: no finlets. Two spines, in front of but separated by an interspace from the 
anterior margin of the anal fin. Ventral thoracic. Teeth small on jaws, vomer, and palatine bones, usually 
lost with age. Scales small. Lateral fine continuous and unarmed. An air bladder bifurcated posteriorly. 
Pyloric appendages numerous or in moderate numbers.
