The .shell here figured is n o t a typical example of this
species as it lacks th e sutui’a l ch es tn u t baud, and th e th in
callous deposit on th e body whorl, and the peritreme is of a
b rig h t c h estn u t hue, and only th e former p a rt is furnished
with granules, -which are v e ry small.

This species is allied to H. Reinga, Gray, -which is said
to come from New Zealand, b u t I may add th a t aU the
specimens in th e B ritish Museum, w ith reliable localities,
are from different pa rts of Australia.
From H. Reinga, i t differs in being of larger and th in n e r
growth, in th e num b e r of th e whorls, which are not so
convex, being ne arly one less, and in having th e underside
of th e la st whorl, which is proportionally larger, more
flattened, especially a t th e umbilical region -ivhich is overspread
by a broadish th in callosity, un ited above to the
o u te r lip. The g reater deflection of th e la st whorl ne ar
th e mouth is another notable difference, and the peritreme
is th in n e r an d more expanded.

There are two specimens brought from th e above locality,
-which I c annot distinguish in any p a rticu la r from this
species. This is n o t th e first record of its occurrence in
Australia, for a sin istra l v ariety is mentioned by Mr.
Gwyn Jeffreys as coming from New South Wales. Its
ad v en t there is n o t to be accounted for w ith certainty, b u t
possibly i t is an introduction of th e common European
shell, as appears to be the case w ith H. n itid a , Müller.

Shell thin, horn-colour, perspectively umbilicated, de-
pressly orbicular, ornamented w ith very close arcuately-
radiating thread-like riblets, which are coarser on the
u p p e r th a n th e lower surface, en tire ly covered with
microscopic spiral striations which are continuous on and
between th e riblets ; spire nearly flat, only slightly

separated by a deepish suture, la st n o t descending in
f r o n t; th e umbilicus occupying one-fourth the width of
th e base ; mouth ro u n d ly -lu n a te ; peristome simple, thin,
columellar margin a little ddated above.
Greatest diameter 7 mill., smallest 6 ; height 3.
Hab. Dupuch’s Is., W e s t A ustralia {Richardson).
This small b u t p re ttily sculptured species is chiefly
characterized by the fine riblets, and th e microscopic
spiral striations, which are not, as in some other species,
in te rru p ted by th e riblets, b u t are continuous over them.
The inferior surface is slightly shining, th e upper n o t so.

The above name is attached to a specimen in the

species so designated, I append th e fo llowing:—
