straight angular lamella joins the lip weakly or scareeljL It does not connect 
with the parietal lamella, which is high but not very long. The columellar 
lamella is high on the columella, and ascends very slightly inward, being 
nearly horizontal. There are two short palatal folds, the lower being larger 
and somewhat more immei’sed. No basal fold. Peristome reflected and 
thickened moderately within. Length 2.2, diam. to edge of lip 1.2 mm.; bYz 
whorls.” 
PAJIILY PUPOIDIDAE. 
The small pupoids assigned to this family are generally larger than the 
remaining Australian pujioid shells, and are either sinistral or dextral, rather 
stoutly built, not conspicuously sculptured, and with the mouth rather square 
the outer lip e.xpandcd, and a parietal lamina, which lies adjacent to the 
junction of the outer liin

As this shell has not yet been figured, and we have no Abrolhos material, 
Smith’s description is reproduced : “Shell sinistral, rimatc, fuscous horny, 
obliquely very finely striate ; whorls 51 / 2 , convex, separated by a deep suture, 
the last whorl scarcely broader than the one preceding, ascending at the 
aperture; s]un' elongate, convex, ])yramidal, subglobose at the apex; aper- 
ture one-third the total length; peristome white, expanded, margins joined 
by a thin callus, a tubercle near the insertion of the lip. Length 4.5, breadth 
2 mm. Aperture 1.5 mm. long. This species may possibly prove to be the 
sinistral form of P. adehtidae Ad. and Angas, which is only known to me by 
the description.” 
P. adelaidae is obviously a larger shell, as is eremicola with which the 
present species was later associated.

When Smith recorded the East Coast pacifica from North-West Aus- 
tralia he noted: “All the specimens from Cassini Island are sinistral; other- 
wise they resemble the normal form.” 
Pilsbry, in accepting this determination, observed that numerous speci- 
mens from all the other localities admitted furnished dextral specimens alone 
and recorded the Cassini Island shells as a form sinistralis^ and this name 
may be used sjiecifieally to keep this shell under review.
