Description
Size: Max length 14.0 cm ML (male); common mantle length 5.0 to 11.0 cm.

Color: Light brownish with conspicuous streaks on the surface of the dorsal mantle and base of the arms. The presence of the transverse stripes gives a 'Zebra' pattern to the animal which makes this species distinctive.

Body is rather slender, elongate and oval in outline; the anterodorsal margin projects strongly with well excavated sides. The fins are moderate in width, begin a short distance before the anterior mantle margin and extend along the sides. At the posterior end of the mantle they are distinctly separated. Hie head is rather small, as long as broad. The arms are subequal and well tapering. The arms are provided with but narrow protective membranes. The dorsal arms are slightly keeled on the outer sides at their distal ends, the lateral arms are strongly keeled along their ventral margins, whereas the ventral ones have strong outer swimming membranes. The arm suckers are more or less globular in males and arranged quadriserially throughout the length. The outer marginal suckers of the arms are smaller in size than the inner ones in the greater proximal portion of the arms; but at the distal tapering end, the outer suckers are slightly bigger than the inner ones except on the ventral pair of arms. The left ventral arm is distinctly hectocotylized in males. It has two groups of normal quadriserial-suckers at its base. The modified portion occupies the greater length of the arms with prominent transverse folds., The suckers are very much reduced in size, the two ventral rows of suckers are arranged very closely and it appears as though they are set in a single row. The dorsal series of suckers are larger in size in the transformed portion. There are 12 to 14 transverse rows of four suckers each on the modified portion. The tentacles end in short and broad clubs. The stem is rounded, A strong swimming membrane is present on the dorsal side of the tentacular clubs and extends a little beyond the end of clubs, the manus of the club is distinctly separated from the tentacles by a deep furrow under the dorsal protective membrane. The protective membrane are well developed and come very closely at the base but they do not unite. The club suckers are arranged in eight oblique transverse series. The suckers are very much unequal in size. In the middle portion of the clubs, three suckers of the third series are Very much enlarged. The cuttlebone of this species is very distinct, its dorsal surface being pinkish in colour. The cuttlebone is elongately ovoid; the dorsal surface is rugose with granulose texture especially in the anterior region and the lateral margins of the posterior end and bears three longitudinal ridges. On the ventral side, the striated zone is rather thick and convex and has a median distinct furrow along the entire length of its ventral surface. The striations are very closely set and broadly truncated with lateral corners slightly produced forwards. There is a small slender but strong spine at the posterior put which is slightly directed upwards.
