18 MARINE SHELLS OF SOUTH AFRICA. 
elongata, angustiuscula, margine dextro paulo incrassato, hic 
illic sparsim fusco maculato ; columella plicis 4, parviusculis 
subeequalibus, leviter obliquis munita. 
Long. 65, lat. maj. 50 millim.; apertura longa 60, in 
medio fata 13. 
Hab. Port Elizabeth. 
This is quite a new form of Turbinella in which the an- 
terior portion answering to the rostrum in the typical form 
(T. pyrum) is quite half as broad as the widest part of the 
shell, and the anterior part of the aperture is so little nar- 
rower than the. posterior, that it can scarcely be called a 
canal. The four small, slightly oblique plaits are situated 
about (or a little below) the middle of the columella. 
The type specimen, which is in very good preservation, 
is in the collection recently presented to the Oxford Uni- 
versity Museum by 8. D. Bairstow, Esq. I have long had a 
specimen of the species, but in such bad condition that I 
would not venture to describe it.
