broken. This specimen resembles Actceonella Bej/richi, Drescher,''' 

 from the Lower Senonian of Lowenberg, but the spire is longer than 

 is usually the case in A. Beyrichi, and the tubercles, which are found 

 on the posterior part of the whorls at the margin of the ledge, 

 appear to be more numerous. Without more specimens a detailed 

 comparison is not possible, especially since A. BeyricJii shows con- 

 siderable variation in the height of its spire and in other characters. 

 ActcBonella cretacea (Miiller),! from the Aachen Greensand, shows 

 a slight resemblance to the Pondoland species.

Description. — Shell globose, consisting of four convex, rounded 

 whorls, which are slightly compressed near the suture. Spire 

 forming about a quarter of the total height of the shell. 



Ornamentation consists of linear spiral grooves separated by 

 broad, flat, nearly smooth interspaces. The grooves are placed at 

 nearly regular intervals, and are closer together and broader on the 

 spire than on the last whorl ; they are marked by fine transverse 

 ridges. 



Aperture large ; narrow and pointed behind, broad and rounded in 

 front. Outer hp with a narrow external thickening, which is 

 broadest near the anterior end. Columella with a single anterior 

 fold. Inner lip with a strong ridge. 



Length 12-5 mm. ; breadth 11 mm. 



Affinities. — This species was identified by Griesbach with Avcllana 

 ampla, Stoliczka,!: but it differs from that form in possessing con- 

 siderably fewer spiral grooves, and in the grooves not being in pairs ; 

 also the interspaces appear to be without transverse ridges.
