ADDENDUM. 



A form of Achatina from North-east Rhodesia in the 

 British Museum collection, has been kindly forwarded us 

 by Mr. Edgar Smith for examination, and, if necessary, 

 description, just in time to be included in this paper. 



Of the size and general appearance of A. morrelli 

 Preston, it differs in the obscurity of the decussate and 

 spiral sculpture, one example, indeed, being almost 

 completely smooth. The oblique dark brown zigzag 

 flame-markings are more than usually regular and hand- 

 some. It may be varietally designated as follows : — ■ 



Achatina morrelli Preston. 



var. kafiiensis nov. (Fig. 8 of Plate). 



Testa ut in typo, sed striis decussatis obscuris vel fere 

 evanidis, superficie nitida, plus minus laevigata, flammis 

 fulgetrinis zebrinis regulariter eximie et oblique praedita. 



Alt. 63. Diam. 30, 



Hab. Chiwallas, Kafue River, N.E. Rhodesia (J. F. 

 Quekett, Esq., in Mus. Brit).
