distinct but not very deep median groove ; the last loculus extends 
over more than one-third the shell, and is bounded posteriorly by an 
almost semicircular line ; the striae are very close ; the limbs of the 
inner cone arise about midway along the shell, pass backwards as low, 
narrow, smooth fillets, and unite behind without forming any deep 
cavity ; the posterior extremity is curved towards the ventral aspect 
and ends in a narrow blunt cone, to the apex of which is attached 
the straight somewhat dorsally directed spine.

The Body is long and narrow, widest near the anterior margin, 
and tapers gradually backwards. The fin is very narrow, only one- 
eighth of the body ; it commences 3 millim. from the margin 
of the body, and posteriorly passes on to the ventral surface 
and terminates 2 millim. from its fellow and 4 millim. from the 
extremity of the body. The mantle-margin has a narrow projection 
over the head, and is evenly truncated venfcrally. The siphon is 
short, not reaching half-way to the space between the ventral arms. 
The Head is of medium breadth, and the eyes prominent 
laterally. 
The Arms are subequal, the order of length being 2, 4, 3, 1, and 
less than one-third the length of the body ; the first two pairs are 
subconical and slender, the third broader and with a web running 
up the ventral aspect, the fourth wider and with a distinct ridge 
along the outer edge ; they all taper to very fine points. Many of 
the suckers are deficient, but they seem to have stood in four series 
throughout ; they are spheroidal and very oblique, the distal 
margin of many has a deep notch : the horny ring is smooth in most 
cases, but occasionally possesses a few angular teeth. The 
hectocotylus is not developed. The umbrella is but little developed, 
its greatest extent being on the ventro-lateral aspect, where it 
reaches the fourth row of suckers. The buccal membrane has the 
usual seven points, the two ventral being the least distinct (as 
usual in female specimens ) ; the spermatic cushion is small. The 
outer lip is narrow, the inner thick and papillate.
