Shore Collection. 2. iv. 26. South Georgia, Grytviken, Sappho Point, i ?, washed up on shore. 

 St. 371. 14. iii. 30. I mile E of Montagu Island, South Sandwich Islands, 99-161 m. Large otter 

 trawl: i specimen. 



Remarks. It is possible that Ammothea australis may prove to be only an eastern 

 form of A. clansi. At any rate the differences between the two are very slight.

This genus differs from Ammothea in (i) the much smaller size of the species, (2) the 

 absence of transverse body ridges, and (3) in the type of the male oviger (cf. Figs. 49 a, 

 55 b and 59 a and b). The tubercles that bear the male genital openings and the openings 

 of the femoral cement glands are not always very prominent (e.g. in A. hoekii, Fig. 60 a).
