Description. — Testa elongato-turritn, transversim striata ; striis 



confertis mqualibiis ; anfractibus medio convexis, basi apiceque 



depressis ; suturis infra marginatis. (Lamarck.) 



Kemarks. — As far as detail is concerned the Egyptian examples 

 of this shell are well preserved, although none of them are quite 

 perfect. The main characters of the species as given originally 

 by Lamarck include its elongate, turreted form, the basal and 

 apical depression of the nearly centrally inflated vt^horls, the regular, 

 elevated spiral striae forming its sculpture, with no evidence of 

 longitudinal striations, and the possession of a prominent suture. 

 The basal margin of each whorl extends obliquely to the suture. 

 The spiral angle of 13° agrees with the type figured by Basterot 

 from the neighbourhood of Bordeaux. 

 Horizon. — Miocene (Helvetian).

Description. — Species having an elongate, narrow, oblong, 

 Bubcyliudrical test, ornamented with transverse sulcations ; whorls 

 convex, divided by a deep suture and bearing nodular plications 

 in the centre ; last whorl with a ring of large prominent tubercles 

 in the upper part, beneath being (in old forms) some minor 

 tubercles separated by spiral sulcations; aperture elongate, subequal ; 

 labrum thick and smooth within ; base curved in adult forms ; 

 canal very short ; columella smooth. 



Dimensions (of medium-sized specimen), — Length, (about) 50mm. ; 

 diameter, 30 mm. 



Eemarks. — The specimens referred to this species are limestone 

 casts, but possessing certain definite characters which suffice 

 for their determination. Both j'oung and adult examples are 

 represented. The narrow, elongate form, its long and deeply
