6Q HENEY CLIFDEN BUBNUP. 



been more favourable for the growth of the shells, but it 

 seems to me more likely to arise through the position in which 

 they were collected. Since I have found the species plentifully 

 under boxes of plants in the Alexandra Park, watered daily 

 in dry weather, I have ceased to look for them in natural 

 surroundings, where they are much less plentiful and their 

 supply of moisture is restricted to the rain and dew. 



It is noticeable that, as far as is known, the typical form 

 has not been found beyond the precincts of the borough of 

 Maritzburg. 



The aberrant forms figured on PI. lY, figs. 45, 46, will be 

 more conveniently discussed after the introduction of the 

 following variety. 



Var. contracta n. PI. IV, figs. 42, 43, 44. 



Shell like E . m a r i t z b u r g e n s i s, typical, with the following 

 differences : Shell much smaller, less fusiform and more ovate ; 

 whorls 6.\, more finely and more obscurely sculptured; aper- 

 ture rounder, proportionately much smaller, and rather less 

 obstructed, with peristome much less expanded, and labral 

 tooth smaller and less widely bifurcate. 



Height 3"32, width 1*58 mm. 



Hab. — Nottingham Road (A. J. Taynton), very plentiful ; 

 also Karkloof and Curry's Post (Taynton), all in Natal. 



The pinched appearance of the relatively small aperture, 

 taken in conjunction Avith the much reduced size of the shell, 

 would, without further consideration, readily induce one to 

 suppose that this form is quite distinct from E. m aritzbur- 

 gensis 3Ielv. & Pons. ; but a close study shows both forms to 

 be built upon exactly the same plan, such differences in detail 

 as exist being merely a matter of degree. The sculpture is 

 of the same nature, and the disposition of the apertural 

 processes is identical, with the one exception of the labral 

 tooth in contracta being less widely ■ cleft. In view of 

 such important coincidence, I should have felt disposed, even 

 if no further evidence were forthcoming, to consider the new 

 form a variety of the older ; but with the support of the
