very probably belonging to A. norvegica. — On account, however, of the difficulty in 

 defining with certainty the species of larvae belonging to this genus, it did not seem convenient 

 to me to include this locality among the new habitats given below, especially as this species 

 is not previously know from this region. The specimen had a shell 1,72 mm. long. 



Habitat: — West coast of Sweden: Bohuslan: E. X. E. of 8tora Sneholmen. 

 Koster; 18. V. 1897; depth down to 160 m.; clay.one juvenis; (coll. J. G. AxDERSSOX); R. M. S. 

 184. N. E. of this island; 26. Y. 1897; depth 160 m.; clay: one juvenis; (coll. J. G. Axdersson); 

 R. M. S. 185. Vaderoarna; depth 70 — 100 m.; coral bottom: one juvenis; (coll. v. GoES); 

 R. M. S. 186. Gullniiir Fjord, no definite locality, probably at Skar; depth 90—110 m.; clay: 

 5 mature females and 4 juvenes; (coll. S. LOVEN); R. M. S. 187. GuUmar Fjord, Fiskebackskil; 

 16. VTI. 1894; clay: 3 mature females; (coll. J. G. Andkrsson); R. M. .S. 188. 



On the label of the two specimens that I got from G. 0. SaRS, no locality was to be found; 

 the specimens in question were, however, certainly from the coast of Norway. 



Distribution: — Christiania Fjord, Holmestrand, t y p e - 1 o c a 1 i t v, depth 90 — 110 ni.

Description: — Female: — 



Shell: — Length 1,63 mm.; length : height about 1,92 : 1; length : breadth about 

 2,17 : 1. Seen from the side (fig. 1) it is elongated, with its greatest height at about 

 the middle and the anterior part somewhat, though only very slightly, larger than the posterior 

 part. The dorsal and ventral margins are almost parallel to each other and are rather weaklv. 

 uniformly and almost equally curved; anteriorly they are somewhat flattened; they pass evenh- 

 into the anterior and posterior margins. The anterior and posterior margins are evenly and 

 boldly rounded, the former being almost semi-circular, the latter somewhat more weakly curved 

 ventrally than it is dorsally. Seen from b e n e a t h (fig. 2) it has its greatest breadth 

 at about the middle and grows narrow rather rapidly towards the ends, somewhat more rapidlv 

 forward. The anterior end is rounded, the posterior end somewhat heart-shaped; the side 

 contours are even. Seen from inside: Medial bristles: ((^n account of the condition of 

 the specimen investigated tlie information given about these bristles is perhajjs not quite so 

 certain as might be desired.) On the rostrum there is a rather distinct, relative) v sparse row 

 of moderately long bristles which runs about parallel to and somewhat inside the anterior 

 margin of the shell. Inside this row of bristles there is only a rather small number of bristles 

 scattered on the rostrum, some moderately long and some very short. On the anterior wall
