Description
Color: The head, dorsal mantle, fins and arms are uniformly of chestnut brown color.

The mantle is long, muscular and cylindrical upto the point of origin of fins and tapers abruptly to a narrow point at the posterior end. The dorsal margin is slightly produced in the middle. The fins are short, muscular and broad with convex anterior margin and from an angle of about 65° laterally. The head is large and as wide as mantle and bears comparatively short arms. The funnel is short, compact and set in a deep pit present on the ventral side of the head; faveola with 7 to 9 longitudinal folds in the central pocket and 3 to 5 lateral pockets on either side. Funnel locking apparatus is fused in its middle portion with the mantle groove so that separating the funnel free from mantle-lock is difficult. The arms are large, strong and compressed with the third pair strongly keeled. Arm suckers are biserial; the protecting membranes have prominent trabeculae; the larger arm suckers are provided with about 12 sharp teeth around the entire rim of the horny rings. The tentacles are short and muscular and laterally compressed. The clubs are small and slightly expanded; the suckers are quadriserial with the inner rows on the manus larger. The larger suckers of the club bear about 20 sharp teeth on the rims of which four are larger and located one in each quadrant. An oval photophoric patch is present on the anterodorsal surface of mantle; there are also two photophores on the intestine.
