F. E. Coivper Reed — New Fossils from Saverfordwest. 367 



CoNRABELLA (?) sp. (PI. XX, Figs. 5, 5a, 5&.) 



There is a small shell occurring in some abundance in the Slade 

 Beds of Upper Slade which may possibly belong to the genus 

 Conradella established by Ulrich,^ but its state of preservation is not 

 quite satisfactory. It seems to consist of a few rapidly enlarging 

 whorls coiled in the same plane, like Cyrtolites ; the whorls are 

 higher than wide and more or less sharply carinated on the back, 

 below which they are somewhat compressed, swelling out to their 

 maximum diameter near their middle. The keel appears to carry 

 a slit-band crossed by rather distant, strong lunulas. The ornamenta- 

 tion consists of rather coarse, raised, fimbriated lines, equidistant and 

 equal in size, and connected by less prominent, short, straight lines 

 at right angles to them and alternately arranged, so as not to form 

 true revolving spirals. No other details can be made out. The 

 ornamentation recalls that found in C. Dyeri, var. cellulosa, Ulrich,^ 

 and the shape is apparently similar. The height of our little shells 

 averages about 6 mm. 



Horizon. — Slade Beds. 



Locality. — Upper Slade, Haverfordwest.
