EoTOMAEiA EoBERTSi, sp. nov. (PI. XX, Figs. 1-4.) 



Shell low, conical, of 5-6 flat whorls; apical angle 90°-110° ; 

 base convex ; periphery angular ; mouth obliquely subrhomboidal, 

 wider than high ; umbilicus very small, deep, partly covered by 

 reflexed inner lip of mouth. Band concave, narrow, with sharp 

 raised borders, the lower edge forming the periphery of the whorls ; 

 lunulge of band very faint. Surface of whorls nearly flat ; 

 ornamented with fine, simple, oblique, curved lines of growth, 

 meeting suture-line above at about 75°, but curved strongly back 

 near band so as to meet it at 20°-25°. Base of shell more or less 

 swollen, especially towards mouth, and marked by strong growth- 

 lines. 



Dimensions average about 18 mm. in basal diameter. 



Sorizon. — Eedhill Beds. 



Localities. — Pi'endergast Place and Lane, Haverfordwest. 



Bemarks. — The genus JEotomaria was established by Ulrich ' for 

 a certain type of shell differing from Pleurotomaria in merely having 

 a notch in the outer lip and no slit ; in the lower edge of the 

 band forming the periphery of the whorls ; in the lines of growth 

 curving more or less forward beneath the band ; and in the surface 

 being marked by simple lines of growth only. The complete 

 definition of the genus was given as follows : " Shell depressed- 

 conical, sometimes sublenticular; base more or less convex, its 

 bulk us\ially nearly equal to the apical part ; umbilicus very small 

 or wanting; volutions not very nuiTierous, sometimes slightly 

 turriculate or strongly angular near the mid-height ; aperture 

 oblique, subquadrate, the inner lip slightly reflected or merely 

 thickened, the outer deeply notched at the peripheral angle ; no 

 slit ; band of moderate width, concave, sharply defined, oblique or 

 horizontal, lying upon the apical side of the periphery. The surface 

 markings consist of fine lines of growth only. These curve
