FOSSILS I'HOM THE MKNEVIAN GROUP. 



Below the strata of Bell Island, there are about 2000 feet 



consisting of sandptones and slates, in whicli no fossils have been 



found except a few fucoids. These with the Bell Island rocks 



n»ay represent tlie .Middle and Upper Lingula Flags. They are 



iniiuediately underlaid by about 2000 feet of slates, sandstones 



and limestones, holding fos.sils which prove them to be of the age 



, ol" the Lower Lingula Flags, or the Menevian group of Salter 



. and Hicks. Fossils in some of the beds arc abundant but very 



, I imperfect. The following are all that are sufficiently well pre- 



, served to admit of description.

Shell small, transversely broi.d ovate, nearly circular, width 

 sligh'ly greater than the length. Ventral valve strongly convex, 

 depressed couical, greatest elevation at about one-third or one- 

 fourth the length !Vom the hinge line. The latter appears to be 

 straight and about one-fifth the width of the shell. In the apex, 

 or the most elevated point of this siiell, there is an irivgularly 

 circular aperture or depression. The dorsal valve is less ixnivex 

 than the ventral but more uniformly so, the greatest elevation 

 near the centre ; bi;ak apparently curved down to the level of the 

 hinge line. 



Surface to the naked eye apparently smooth, but when magni- 

 fied showing very tine concentric striae. The width of the largest 

 specimen of the dorsal valve seen, is about one line ; length a little 

 less. This species dccurs at Chapel Arm, in Trinity Bay. 



Mr. Davidson has figured and described'"' under the name <>l' 



0. saggitatis, Salter, a species from the Menevian group, North 



Wales, which is closely allied to this, the only difference, (so far 



' as can be made out without comparison of specimens) being, that 



the English species is about double the size of ours. As I un-
