new Mollusca from South Africa. 105 
Two specimens, neither in very good condition. 
The shape is peculiar, ovate-pyramidal, the last whorl 
rapidly increasing, somewhat effuse, the other whorls small 
in proportion; the surface, excepting that of the basal half of 
the last whorl, which is smoothish though longitudinally 
wrinkled, granato-decussate. 
This appears to be a very distinct new form.

A smoothish glassy species, to which we cannot assig 
place as the young of any South-African form with which 
we are acquainted, several of the specimens before us being 
apparently full-grown.

(PI. ILL. fig. 5.) 
B. testa anguste umbilicata, omnino pellucida, lete cornea, tenuis-

Hab. Pietermaritzburg (Hl. Burnup, Esq.). 
A very pretty transparent, horny, pyramidal species, six- 
whorled, attenuate towards the apex, the last whorl shoul- 
dered, somewhat broadened ; whorls ventricose and impressed 
at the sutures, narrowly umbilicate; mouth roundish; peri- 
stome thin, simple, and much reflexed triangularly at the 
columellar margin, covering the umbilicus. 
Allied to B. conulus, Reeve, from which, however, it will 
be found on comparison to be quite distinct.

(PI. III. fig. 6.) 
B. testa anguste umbilicata, conico-pyramidali, corneo-pellucida,
