 describe these would require further collections. In the upper 

 strata there are yet two or three new species of Liiigula, of 

 which we have only fragments. 



FOSSILS FROM THE MENEVIAN GROUP. 



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

 consisting of sandstones and slates, in which no fossils have been 

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

 may represent the Middle and Upper Lingula Flags. They are 

 immediately underlaid by about 2000 feet of slates, sandstones 

 and limestones, holding fossils which prove them to be of the age 

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

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

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

 served to admit of description. 



Obolella ? MISER, spec. nov. 



Shell small, transversely broad ovate, nearly circular, width 

 slightly greater than the length. Ventral valve strongly convex, 

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

 fourth the length from 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 shell, there is an irregularly 

 circular aperture or depression. The dorsal valve is less convex 

 than the ventral but more uniformly so, the greatest elevation 

 near the centre ; beak apparently curved down to the level of the 

 hinge line. 



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

 fied showing very fine concentric stria3. The width of the largest 

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

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



Mr. Davidson has figured and described* under the name of 

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

 Wales, which is closely allied to this, the only difi"erence, (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-
