The figures of E. sylvia M.&P. (PI. Ill, figs. 18, 19, 20) and 

 the comparison between tliat species and E. melvilli (p. 56) 

 may here be referred to, for there is also some general like- 

 ness between the former species and E. mooiensis, which I 

 think an examination of the figures and a perusal of the text, 

 above indicated, will show to be only superficial. 



The greater height and narrower, more cylindrical form of 

 E. mariae Melv. & Pons., and the prominent tooth situate 

 subcentrally on its columellar lip, prevent the possibility of it 

 being confused with this species. 



The following are the dimensions of a few specimens of 

 E. mooiensis which, in addition to the type, I have mea- 

 sured : height X width, 2-65 X 1-25, 2-65 x M6, 2-55 x 1-21, 

 2-43 X 1-19, 2-33 x M8, 2-25 x M2, 2-21 x 1-19, 2-18 x 1-18 

 mm. 



This species is plentiful in its locality, almost to the exclu- 

 sion of other species of the genus, but has not yet been found 

 elsewhere. Whilst visiting the district twice, during the 

 Christmas holidays 1910-1911 and 1911-1912, I collected 

 224 specimens of Enne«, 220 of which belong to this species 

 and 4, all distinct inter se, to different, larger species not 

 yet identified.

Ennea maritzburgensis Melv. & Pons., Ann. and Mag. Nat. Hist., 

 vol. xii (1893), p. 107, pi. iii, fig. 11. 



The original description seeming to require some slight 

 revision, and the type being unavailable to me, I have chosen 

 a normal specimen from the original locality as my type of 

 the following emended description and accompanying new 

 figures (PL IV, figs. 39, 40, 41). 



Shell small, rimate and narrowly perforate, thin, whitish, 

 subdiaphanous, shining ; whorls 7, slightly convex, of which 

 the first 2, constituting the protoconch, are smooth all over, 

 the next 4^ are delicately, transversely striate immediately
