 above-mentioned species of G, 0. S.\US's either. Nor does G. W. MOU-EU, 1912, p. 4G, inchulc 

 it as a synonym of A. dliptica.* 



Habitat: — Ireland: Strangford Lough (type locality); no information about 

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

 2 juvenes; coll. G. S. BRADY.

Asterope Grimaldi n. sp. 



Description: — F e ni a 1 e : — 



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 anteriorly. 

 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 contom's are evenly cui'ved. 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 

 moder&te 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 short bristles, which is partly^ very sparse and sometimes not very distinct. 



* ,,A. elUp I ica" is also found by E. Graeffe, 1900, p. 34. No description is given and il is consequent ly quili^ 

 impossible to say anytliing about the synonymy of this form.
