Description
Color: The external colouration is very characteristic. In live condition the whole body is dusty brown in colour with a number of blue to violet coloured small rings over the mantle, head and arms; the colouration of the rings is very intense and bright; sometimes dark bands appear on the body. The coloured rings are very conspicuous against the general dusty brown colour of the body. The somewhat wide circular rings assume the form of small speckles and the dusty brown colour of the body is lost on preservation.

The mantle is small, globular to elongate and smooth. The head is small, slightly narrower than the mantle, the pallial aperture is not more than the width of the head. Eyes are very small and not prominent. The funnel is small and narrow, the anterior free portion is about half the length of the funnel. The arms are moderately long, subequal in length, slightly stout at the base and have attenutated tips. The web is well developed between the arms and continues along the margin of the arms for some distance forming a wide membrane. The web between the third and fourth arms is wider than that between other arms. The third right arm in the male is hectocotylized and the modification is simple; the ligula is very small and rounded at the tip, having only a shallow groove in the middle with faint transverse ridges. The calamus is well developed and the spermatophore groove is broad.
