Metoptoma Oephyne. (N. sp.) 



Description. — This species, like M. Melissa, is almost completely con- 

 ical, but more obtuse. The base is oval, slightly more narrowed in front 

 than behind. Apex erect, acute, and a little in advance of the centre. 

 The surface of the cast exhibits eight or nine shallow concave undulations 

 running round the shell, parallel with the plane of the base, each about 

 one line wide. 



Length, 12 lines ; width, about 9 lines ; height, 8 lines. 



Locality and Formation. — Point L^vis ; in hmestone No. 2, Quebec 

 group. 



Collector. — R. Bell. 



Metoptoma Augusta. (N. sp.) 



Description. — Shell irregularly conical, the anterior side flattened, and 

 the posterior rounded. Apex a little in advance of the middle, and appa- 

 rently a little curved backwards. The flattened anterior side gives to this 

 species the aspect of a large Calceola. The front margin is not preserved, 

 but appears to have been nearly straight, the sides gently convex, and 

 posterior margin broadly rounded. Surface unknown. 



Length, li inches ; width, IJ inches ; height, 13 lines. 



I am not quite sure that this is a symmetrical species. Only about half 

 of the specimen is preserved, and the flat anterior side does not appear to 

 be at a right angle to the longitudinal axis of the shell. 



Locality and Formation. — Point L^vis ; in limestone No. 2, Quebec 

 group. 



Collector. —'i. Weston.
