Remarks. The present form has been erroneously identified by Brady 

 with P. obliqvum, and must of course have a new specific name. I propose 

 to name it as above. It may be easily recognized both from P. obliqvum and 

 most other species by the rather short and clumsy shape of the shell. 



Occurrence. I have had an opportunity of examining 3 well-preserved 

 female specimens of this form. They were found in my material of Para- 

 doxostoma collected at different times and in different places of the Norwegian 

 coast, the exact locality were they occurred not being ascertained. 



Distribution. British Isles.

Specific Characters. Female. Shell, seen laterally suboval or elliptical 

 in shape, greatest height in the middle and scarcely exceeding half the length, 

 dorsal margin gently arched and sloping nearly at a straight course to the 

 hind end of the shell, ventral margin very slightly sinuated in front and evenly 

 bowed behind, anterior extremity obtusely rounded off, posterior gradually 

 contracted to an obtuse corner not sharply defined either above or below; 

 seen dorsally oblong oval in outline, with the greatest width in the middle 

 and about equal to 2 /s of the length, both extremities obtusely pointed and 

 nearly equal. Valves thinner and more pellucid than in the preceding species 

 and almost bare from hairs. Anterior antennae comparatively less prolonged, 

 with the 2nd joint of the terminal part not nearly twice as long as the 1st. 

 Posterior antennae likewise somewhat stouter than in P. Bradyi, but otherwise 

 of a rather similar structure. Legs comparatively short and stout, with the last 

 joint less prolonged than in the other known species. 



Colour of shell not yet ascertained. 



Length of adult female 0.58 mm. 



Male not observed. 



Remarks. I think I am right in identifying the above-described form with 

 Brady's species, though the figures given by that author in his Monograph do 

 not fully agree with those here reproduced. Yet, in a subsequent memoir, 

 edited by Brady and Norman in common, new figures of the shell have been 

 given, and these figures are in better accordance with the form examined by 

 me. The species seems to be nearest allied to P. Bradyi, but is of much
