and would be much larger when the animal was alive. On the second left arm the enlargement of the 

 suckers is much less marked ; but this arm is much smaller than the others and has very likely been mutilated 

 at some time or other. The third left arm corresponds almost exactly with its fellow of the opposite side. 

 On the left ventral arm the eighth sucker is the largest and attains a diameter of I cm. The third right 

 arm is hectocotylised (Fig. 2). The groove along the outer ventral edge is extremely well developed 

 having a breadth of about 3 mm in the middle of the arm. The extremity (Fig. 3) is bluntly rounded and 

 does not present the usual longitudinal groove on the inner aspect. Instead of this there is a deep pit 

 with folded margins about three-quarters of the distance from the base to the apex, and there are a number 

 of small cracks around this as well as here and there along the sides of the tip. These have every 

 appearance of being normal structures, but it is just possible they may be due to injury or defective 

 preservation. 



The Surface except for the wrinkling due to the spirit appears to be smooth all over. There 

 are no definite papillae or excrescences of any kind. 



The Colour is a dull purple somewhat paler below.

This species is distinguished from all others known to me by the structure of the extremity of the 

 hectocotylised arm, and by the fact that enlarged suckers are borne on all the arms except the ventral 

 pair. It is most likely that this character will be found to be confined to the males, but I am not 

 acquainted with any named form from South Africa which could be the female of this species. 



Moschites nigra n. sp. 



Locality: Angra Pequena. Seven specimens, 1 <?, 6 ? (H 1358 — 1363). 



The Body is flattened ovate, broader behind than in front, with a faint indication of a median 

 groove on the lower surface. The mantle opening extends half-way round the body, terminating a 

 little behind and below each eye. The siphon is of rather more than average length, slender and conical, 

 reaching fully half-way to the margin of the umbrella between the ventral arms. 



The Head is comparatively narrow and the eyes not very prominent. 



The Arms are sub-equal ; the ventral pair shortest ; the three superior pairs nearly equal, the order 

 of length thus being 1 = 2 = 3, 4 ; they vary from four and a half to five times the length of the body, 

 and taper gradually to very slender points. The umbrella is well developed all round, but is narrower 

 between the ventral than between the dorsal arms. The suckers are in a single series for the greater 

 part of all the arms, but for a few centimetres in the proximal third of the arm, where they are the largest, 

 they are displaced alternately to either side of the middle line, though without forming two definite rows. 

 The margin of each sucker bears a ring of close-set knobs; the disc is covered with a thick cuticle, which 

 is very easily detached, and when it is removed shows very clear radial grooves, reaching to the central
