 Zool. Soc./ 1861, p. 155. 



Hab. — Isipingo, Natal (H. Burnup). 



The single specimen at hand is attached to the spire of a 

 Con us ceylanensis, and is so much corroded like the shell 

 also that it is not possible to say with certainty that it belongs 

 to this species, originally described by Morch from West 

 Africa. The colour is the same, but I cannot trace the longi- 

 tudinal sculpture (" liris circiter vi obsoletissime nodulosis") 

 as described by Morch. The growth-lines or wrinkles are 

 quite strong as in leucozonias.

A s^jecies without striking features. Of the spiral lira?, one 

 which borders the consti'iction at the lower part of the whorls 

 is most conspicuous. Altogether there are about seventeen 

 lira3 on the penultimate whorl with a few intervening threads 

 here and there. 



Of the two specimens examined, that from Isezela has the 

 oblique brownish striga? more broken up into dots than the 

 other.
