 douht as to its identity.

Nuculana stilla, M'Coy sp. PI. v., fig. 11. 



Several specimens of this little shell occur in the upper marine 

 band at Kilkee. The type specimen came from Dromod, co. Leitrim. 

 N. stilla occurs in the Pendleside series in England, but does not 

 seem to be confined to that series. 



Locality — Kilkee, = Horizon of Millstone Grit series. 



Cypricardella selysiana, de Koninck. PL v., fig. 12. 



The species is not uncommon in the upper marine band, Puffing 

 Hole, Kilkee, = Horizon of Millstone Grit. 



Chsenocardiola Footii, Baily sp. PI. v., fig. 13. 



I regard this shell as an important zonal index. It occurs in beds- 

 of a similar age at Clavier, near Dinant, Belgium, and in Derbyshire 

 and ? Lancashire. East and west of Ireland. 



Locality — Roscliffe, County Clare, = Horizon of Pendleside series.

Specific characters. — Spire elongate, composed of six whorls which 

 increase fairly rapidly in size. The whorls are convex from above 

 downwards ; suture deep ; aperture ovate ; shell ornamented with 

 longitudinal striae, occasionally decussated by spiral lines. 



Pimensions — Height, 5 mm. Breadth, 3 mm. 



Localities — England : The Pendleside series of Crimsworth Dean, 

 near Todmorden. Ireland: Beds immediately above the Carboniferous 

 Limestone, Eoynes Island. 



Ohservatiotis — Baily gave due attention^to the alliance of his species 

 with Brown's shell ; and separated his shell, because he thought the 

 last whorl was proportionately larger, and the surface was not
