Description
Size: 100 mm.

Color: In preserved specimens brownish or greenish, some of the rings sometimes darker. Body and tail sometimes spitted with black pectorals and often also dorsal with black dots.

Much flattened, the greatest depth about 14 in length without caudal. Head 3-3.3 in length without caudal. Snout 1.8-1.9 in head, slender, much flattened, rounded in front, sides with a row of antrorse spines which are less conspicuous in larger specimens. Greatest breadth at base of pectorals 5.6-6.9 in length without caudal. Tail consisting of 12 rings, the posterior rings fused. The anterior tail rings quadrangular in cross section, the posterior ones much depressed. Two ridges on back, parallel to each other, starting from a supraorbital ridge and continued to end of tail, but almost flattened out on 5 posterior rings. A lateral ridge on each side, beginning above pectoral and disappearing on sides of tail. In young specimens the dorsal and lateral ridges have a spine at the end of each ring, the spines being directed backwards, but they get more obtuse and almost disappear in older specimens, excepting those of the lateral ridge in the posterior part of the tail, where there are two spines on each ring, one directed forward at the beginning, and one directed backward at the end of the ring. Anus slightly nearer tip of snout than base of caudal. Dorsal and anal opposite to each other, on second to fourth tail ring. First dorsal and anal rays longest, the following gradually decreasing in length. Caudal obliquely truncate. All pectoral rays flexible and articulated, the fifth to seventh longest, somewhat longer than snout. Ventral spine close to the first ray, which is long, curved, and articulated in its distal part. The second ray minute.

Remarks: Values in above description denote proportions.
