The Pondoland specimens do not seem to differ at all from the 

 examples found in the Ariyalur Group and figured by Stoliczka " as 

 Turritella {Zaria) multistriata, Eeuss. Holzapfel and Petho have 

 given reasons for using Goldfuss' f name, quadricincta, rather than 

 Tmdtistriata, Eeuss. 



Turritella Bonei is very closely allied to T. quadricincta, I but 

 whether or not it is identical with the latter can be determined only 

 by a comparison of specimens, which I have had no opportunity of 

 doing. The examples of T. Bonei agree more nearly with the figures 

 of T. quadricincta given by Goldfuss and Petho, than with those 

 given by Favre, Holzapfel, and Miiller. 



The type specimens of T. Meadi, Baily, are chiefly internal casts, 

 but in one fragment some of the shell is preserved and appears to 

 possess more numerous ribs than T. Bonei. Baily's figure is a 

 restoration, the form of the shell being drawn from an internal cast 

 and the ornamentation from the fragment mentioned above. 



The types of T. Bonei and T. Meadi are in the Museum of the 

 Geological Society of London.

Plate XXXVIII., fig. 13. 



Description. — Shell small, of moderate length. Spire formed of

last two or three are angular owing to the development of a carina 



in front of the middle of the whorls ; behind the carina these whorls
