and the limbs {pi. LIX, figs. 19 and 20) that it nnist be said that synonyiuization is impossible. We 

 have perhaps here too, however, mistakes in observation and drawing on the part of the authors 

 — it is certain that the limbs are exceedingly incorrectly drawn — nor does it seem impossible, 

 as I point out in the remark under A. ahyssicola, that in pi. LII there has been confusion between 

 figures 17 and 19. — This species described by these writers cannot be synonymized with the 

 above-mentioned species of 6. 0. Sars's either. Nor does G. W. Muller, 1912, p. 46, include 

 it as a synonym of A. elliptica.* 



Habitat: — Ireland: Strangford Lough (t y p e 1 o c a 1 i t y) ; no information about 

 the depth and the nature of the bottom was to be found on tlie label: 2 mature females and 

 2 juvenes; coll. G. S. BRADY.

Description: — Female: — 



Shell: — Length, 1,53 — 1,7 mm.; length : height about 2,2:1; length : breadth 

 about 2,4 :1. Seen from the side (fig. 1) it is very much elongated with the greatest 

 height at about the middle and with the anterior and posterior parts of about the same height. 

 The dorsal and ventral margins are almost parallel and are very weakly, uniformly and almost 

 symmetrically curved, the ventral margin is, however, as a rule, somewhat flattened anteiiorly. 

 These margins pass evenly into the anterior and posterior margins without forming any corners. 

 The anterior and posterior margins are boldly rounded, almost into semi-circles, and have about 

 the same shape; the latter is, however, somewhat flattened dorsally in most cases. Seen 

 from beneath (fig. 2) it is narrow and oviform, with its greatest breadth at about two- 

 thirds of the distance along the shell; the posterior end is rounded somewhat more broadly 

 than the anterior end and the side contours are evenly curved. Seen from inside: 

 Medial bristles: On the rostrum there is a sparse row of stiff and moderately long bristles, running 

 parallel to and somewhat inside the anterior margin of the shell. Within these there are a 

 moderate number or rather few scattered bristles, most of them short, some about as long as 

 the bristles in the anterior row. In the incisur there are a few stiff and moderately long bristles, 

 a number of which are scattered, and some are often arranged in a sparse row running about 

 parallel to and somewhat inside the ventral margin of the rostrum. On the part just behind 

 the incisur there are also a moderate number or rather few bristles. Some of these are often 

 placed in a sparse row running about parallel to and somewhat inside the ventral margin; these 

 bristles are moderately long. The others that are situated farther in are scattered and more 

 or less short. About parallel to and somewhat within the ventral margin of the shell there is 

 a row of rather sliort bristles, which is partly very sparse and sometimes not very distinct.
