mediate forms having been observed in the very large series 

 examined. 



Dr. Sturany has kindly perused my MS. and compared my 

 figures with his original shells, and concurs in the elimination 

 of the two vai'ieties, simillima and cylindrica. 



Ennea elliptica Melv. & Pons, f . typica, PI. Ill, 

 figs. 7, 8, 9, 10, 11, 12. 



Ennea elliptica Melv. & Pons., Ann. and Mag. Nat. Hist., vol. ii 

 (1898), p. 126, pi. vii. fig. 2 ; Connolly, Ann. S. Af. Mus., vol. xi 

 (1912), p. 73. 



In the original figure, which fairly well represents the 

 characters of the peristomatal dentition, omitting, however, 

 the internal columellar plait, the aperture is drawn out of all 

 proportion to the rest of the shell. It is shown to occupy 

 about 35 per cent, of the whole height, whereas in normal 

 specimens it does not occupy more than about 28 per cent. 

 This would make it appear either that the type is a malformed 

 shell or that the figure is bad. As the authors had before 

 them, at the time the description was written, four specimens 

 agreeing in detail, it is not likely that the type is abnormal ; 

 therefore it is to be inferred that the figure is incorrect. In 

 any case it seems desirable to publish a new figure, which is 

 given on PI. Ill, fig. 7. This drawing represents a normal 

 shell from the original locality in the Botanical Gardens,^ 

 Maritzburg. Fig. 8, drawn from another specimen from the 

 same locality, represents the right side of the shell and shows 

 the striate sculpture on the last half whorl. 



This species is very interesting in exhibiting, through large 

 series from difl:erent localities, the undoubtedly close relation- 

 ship between forms which, but for the intermediates, might 

 possibly have been taken to be distinct species. 



' The Botanical Gai'dens, Maritzburg, as a faimistic locality, must not 

 he looked vipon with suspicion as indicating the probability of moUuscs 

 having been introduced with plants from a distance. The spot indicated 

 is a bush-clad hill within the boundaries of the gardens but not dis- 

 turbed by cultivation.
