ON SOUTH AFUICAN ENNE.?':. 31 



The new varieties introduced are as follows : Ennea isi- 

 pingoensis Shir. var. sturanyi ; E. elliptica Melv. & 

 Pons. var. manca ; E. elliptica ilie/y. & Pons. var. caslata; 

 E. farquhari Melv. & Pons. var. avena; E. darglensis 

 Melv. & Pons. var. illovoensis; E. maritzburgensis 

 Melv. & Pons. var. contra eta. And the species, described 

 as new, are : Ennea mel villi, E. mooiensis, E. inhluza- 

 niensis, E. ponsonbyi. 



It has also been thoug-ht desirable to re-describe and re- 

 figure a few forms whose original descriptions and figures 

 iippeared to be erroneous or insufficient in detail, or had been 

 published in works not easy of access to South African 

 readers. 



The difficulty presented by the writer's inability to examine 

 the types in the British Museum has largely been overcome 

 by the readiness of friends on the spot to compare them with 

 specimens and drawings sent for the purpose, and to report 

 upon such coincidence or disagreement of character as might 

 be observed. To those ready hewers the writer's most cordial 

 thanks are extended, and their special services are duly 

 acknowledged under the heads of the several species involved. 

 No less are sincere thanks due to those who have supplied 

 material for study, prominent among whom are Messrs. J. H. 

 Ponsonby, J. Farquhar, and A. J. Taynton. 



The types of the species and varieties described as new, 

 together with a few of the other shells figured herein, will be 

 deposited in the British Museum. A reference to the explana- 

 tion of the plates at the end of this paper will show the 

 resting-place of each shell figured.

Ennea isipingoensis Sturany; and its varieties. 



Through the kindness of Dr. Rudolf Sturany in lending 

 me his types of this species and its three varieties described 

 at the same time, I have been enabled to acquire a better
