HOYLE: REPORTS ON THE CEPHALOPODA. 16 
The Body is oblong, rounded behind, very little longer than broad ; with a 
slight depression in the ventral median line. The mantle-opening extends less 
than halfway round the body, terminating some distance below and behind the 
eye. The siphon is small and bluntly terminated, and would reach only about 
one-third of the distance from the mantle-margin to the edge of the umbrella. 
The Head is short, and, owing to the prominenee of the eyes, considerably 
wider than the body. 
The Arms are sub-equal in length, the dorsal being somewhat shorter than 
the others: on the average they are three times as long as the body (measured 
to the eye). The umbrella is well developed between each pair of arms, though 
between the dorsal arms its radius is only 12 mm., whilst between the ventral 
itis 18 mm. (measured from the mouth). The suckers are of average size, 
closely set and rather prominent : the three proximal ones form a single series. 
On the third left arm the eleventh sucker is absent: a similar loss seems to 
have affected the second right arm, but to be in process of repair, for a small 
Sucker is growing in the space between the ninth and eleventh, which was 
probably formerly oceupied by a much larger one. No heetocotylus is present. 
The Surface is rough: the back is covered with granulations which become 
smaller on the sides and gradually vanish in tbe centre of the lower surface. 
These are also found on the external surface of the umbrella and on the proxi- 
mal moiety of the arms. Very minute granulations occur also on the internal 
Surface of the umbrella and the adjacent portions of the sides of the arms, 
There are no cirri and no papillae which are much larger than the others. 
The Color (in spirit) is a dull violet, shading into ochre below. On the 
sides lighter patches are indistinctly seen separated from each other by darker 
veins. In front of and below each eye between the bases of the lateral arms is 
an eye-like spot, distant about 7 mm. from the eye and 8 to 11 mm. from the 
umbrella margin (Plate 4, Fig. 4). It has a pale whitish centre, surrounded 
bya dark ring; this in its turn is bounded by a broader area of the paler color 
of the skin, enclosed by a narrow dark line.
