Siifflementary description: — Male: — 



Shell: — Length: C. Claus (1891 a) gives this as 1,2 — 1,3 mm. (the same for S and ?); 

 G. S. Brady and A. M. Norman, 1896: 1,4 mm.; V. VAwa, 1906: 1,5—2 mm.; G. W. MUller, 

 1906 a and 1912: 1,0 — 2,0 mm., ,,die groBen Individuen iiber ... 1,8 mm, stammen aus der 

 Arktis". The male specimens investigated by me had the following lengths: Skager Rak and 

 Cattegat: 2,05 — 2,25 mm., Lofoten: 2,1 — 2,25 mm., Arctic Ocean, 2,05 — 2,2 mm., Atlantic 

 Ocean (S. A. E., PI. Station 134): 1,2 mm., Antarctic Ocean: 1,45 — 2 mm.; specimens from 

 1,85 — 2 mm. long were found only at the most southerly station (S. A. E., PI. station 59 b). 

 Length : height about 2,6 : 1; length : breadth about 2,9 : 1. Seen from the side it 

 is of about the same type as is reproduced in the adjoining fig. 1, i. e. perhaps somewhat more 

 elongated and with a posterior part that dominates somewhat less than would appear from the 

 descriptions mentioned above. The spines just in front of the posterior dorsal corner of the 

 right valve vary somewhat in number, from one to three were found. In the Scandinavian 

 specimens the right valve always had at the postero-dorsal corner a process of about the type 

 reproduced in the accompanying fig. 3; in the male specimens from the Antarctic Ocean investig- 

 ated by me there was never any such process; see the accompanying fig. 4. Seen from 

 b e 1 o w (fig. 2), it has its greatest breadth at about the middle and has side contours that are 

 somewhat irregularly and weakly undulating posteriorly; anteriorly it is broadly rounded with
