Voluta Vereonis, spec. nov. Pl. i., fig. 5. 
Elongate-fusiform, spire turrited, short ; aperture about two- 
thirds the total length. 
Pullus hemispheric of two and a half smooth whorls; spire- 
whorls three and a half, the anterior ones angulated antemedially 
and nodosely-plicate on the angulation, extending to the anterior 
suture, but evanescent towards the posterior suture. Body-whorl 
with ten nodosities on the periphery, abruptly terminating plica- 
tions, which occupy the median area; at about the anterior- 
fourth the suture commences to ascend on the penultimate whorl, 
finally attaining to the angulation; outer lip incrassated, but 
bevelled-off inside to a thin simple edge; columella with four 
plications. 
The sculpture consists of axial linear grooves, hardly visible by 
the unaided eye, and transverse wavy-strie ; the latter occur on 
the spire-whorls and the shoulder of the body-whorl, and are 
visible only by the aid of a lense. 
The colour is whitish, with intricate-linear fulvous markings ; 
chesnut spotted around the posterior suture, and on the body- 
whorl also about midway between the angulation and the front.

Habitat.—Two adult specimens, as shown by the incrassation 
of the lip and its ascension on the spire, were taken alive by Dr. 
Verco, from 13 fathoms in Yankalilla Bay, St. Vincent Gulf; 
and a living adolescent example from 30 fathoms off Corney 
Point, Spencer Gulf. Two dead shells dredged in Investigator’s 
Straits (Zzetz, in 8. Aust. Mus.); also one dead shell in 22 
fathoms by Dr. Verco. 
Affinity.—In its general characters this new species resembles 
a dwarf V. Areuslere, Angas, being about one-third its size; from 
which it differs by its proportionately shorter spire (the ratio of
