ON SOUTH AFRICAN ENNE^. 59 



Since the above was written, my attention lias fallen upon 

 two shells collected by me in the year 1900 in the Beach Bush 

 at Lower Umkoraaas, which could not be identified at the 

 time but undoubtedly belong to this species. Their dimen- 

 sions are as follows : 



Height X width: 1-94 x 0-79, 1-82 x 0-83 mm. 



Though among the smallest measured, their ratio of width 

 to height corresponds with the typical foi-m rather than with 

 the more obese variety vitreola, considered below. In fact, 

 the higher of the two is the most attenuate of all. 



This newly cited locality is interesting, as but few species, 

 at least in typical form, are found both on the coast and in 

 the higher altitudes of the midlands. 



Var. vitreola [Melv. & Pons). 



Ennea vitreola Melv. & Pons., Ann. and Mag. Nat. Hist., vol. i 

 (1908), p. 130, pi. vii, fig. 3 ; Coimolly, Ann. S. Af . Mus., vol. xi 

 (1912), p. 87. 



I cannot separate this form from the preceding, except on 

 the grounds of its more ovoid contour with shallower sutures, 

 and the slightly weaker development of the peristome and 

 peristomatal processes. The general appearance of the shells 

 in other respects, their sculpture, and the arrangement of the 

 peristomatal processes, are almost identical. The type having 

 been reported lost, I sent the better of the co-types to take 

 its place; and this, I believe, is the specimen now in the 

 British Museum. The remaining co-type is in my collection 

 at the Natal Museum.^ 



Although the exact locality at Hilton Road has been dili- 

 gently searched several times since the original shells were 

 discovered, no further examples of the variety, and no 

 specimen of the typical form at all, have been found until the 

 present time (November, 1913), when, a final effort being- 

 made, one specimen was obtained confirming the varietal 



' Connolly's statement, in loc. cit., that the type is in Maritzburg, 

 is incorrect.
