One specimen (N 45) was examined and sketched in life and afterwards sectioned. This, though similar in many respects to A. michaelseni, Burger, has been separated from it by reason of the cerebral organs, armature and the number of nerves in the pro- boscis. It has been identified with A. lecointei, Burger, on the shape, head glands, brain and cerebral organs. Much should have been added to make the original description adequate, for there is great similarity in the anatomy of the closely related species lecointei, gerlachei, falklandicus and marioni. The length was 20 mm. and breadth 2-3 mm. A specimen sketched by Mr D. D. John at St. 156 was 23 mm. long. Form and colour in life. The size and shape is remarkably uniform. The body is stout, almost circular in cross-section, bluntly pointed at the head and tapering to the tad. The head is marked off from the body by a transverse groove deep ventrally and incomplete dorsally. At each side the groove takes the shape of a backwardly directed V, and from
