surface is diversified with rows of longitudinal granules; the lateral 
portions are rather coarsely reticulated. The locomotive disk is paler. 
The genital orifice, behind the right tentacle, is a large slit, with a 
furrow running from it obliquely forward and downwards, much as in 
Aplysia. 
Found at the Bay of Islands, New Zealand. Drayton. 
From the preceding description it is plain that this species is sepa- 
rated from the other Bulimi by many important characters. ‘The 
lateral expansion of the foot, like a broad flounce, its broadly rounded 
termination, its disproportionately short and small tentacles, all unite 
to separate it as a distinct subgenus, approximating to the true Auri- 
cula. Some such striking deviation from the ordinary type we might 
naturally expect in an isolated region so remote.

ANIMAL cream-coloured, depressed, rather slender, much thinned at 
the edges; posteriorly flattened, and terminating obtusely. Surface 
with longitudinal, slender, lozenge-shaped reticulations; marginal 
limbus rather broad, marked with rather distant oblique lineations. 
Inhabits the Feejee Islands. 
Mr. Reeve seems to regard his B. eximius, a South American shell, 
as identical with this, though I apprehend that they are really quite 
different.
