distance from band to suttire, and one weaker one nearer the suture. 

 Band peripheral (submedian on upper whorls), rather wide, trilineate 

 with raised linear margins and stronger submedian raised line; lunula 

 frequent, rather strong. Outer face of whorls with faint revolving 

 •carina below band at about twice its width, and another fainter one 

 at same distance below. On outer and lower surface of basal whorl 

 below the band there are in addition distinct spiral revolving lines 

 regularly and closely placed. Upper surface of whorls crossed 

 by regular, strong growth-lines meeting band at 60°, and continued 

 below it on outer and lower surface of whorls. 

 Dimensions : 



Height about 18 mm. 



Basal width ,, 12*omm. 



Horizon. — Slade Beds. 



Locality. — Lane between Slade Hall and Pelcorabe Bridge. 



Remarks. — This species, though at present too imperfectly known 

 io merit a distinctive name, undoubtedly belongs to the genus 

 Zophospira as defined by Ulrich,' and it possesses many points of 

 resemblance to L. bicincta (Hall),^ but the band and carinee are 

 rather different. It is probably distinct from any British Bala 

 species so far described, though M. pulchra, McCoy, ^ seems allied 

 to it. But an examination of the supposed type of Pleurotomaria 

 turrita, Portlock,* in the Jermyn Street Museum has convinced me 

 that its nearest relation is found in this species, and it may best be 

 compared with it, pending its specific separation. 



LiospiRA sp. (PI. XX, Figs. 7, 7a.) 

 Shell heliciform, low, depressed-conical, of 4-5 rounded whorls 

 •coiled into a low spire ; base convex, rounded ; whorls increasing 

 in size rather rapidly to mouth ; sutures more or less sunken ; apical 

 angle 130° or more ; body-whorl higher than spire, with rounded 

 periphery. Band of moderate width, not prominent, subperipheral, 

 situated on body-whorl a little above middle, hidden on other whorls 

 by their overlap. Ornamentation of shell consisting of fine, trans- 

 verse lines of growth, curved back sharply to meet band, and 

 continued on lower surface of body-whorl (base not well preserved).

Height 7'5 5 mm. 



Diameter 11-5 8mm.

Localities. — Eoadside near St. Martin's Cemetery, Haverford-

Remarks. — The specimens are not sufficiently well preserved to 

 determine the species, but their reference to the genus Ziospira as 

 ■defined by Ulrich" is indisputable. So far as this form can be
