know not the rank or true affinities of the present group. It is evidently
either one of the lowest types of form, or a sub-genus. We have received
both sexes of these insects from Java, where the species appears to be
common. The resemblance of this group, to _Rhetus_ and _Marius_, would seem
to indicate points of strong natural analogy.
We adopt the original specific name of Cramer: for we cannot, at this
moment, trace the species in the voluminous works of Fabricius.

GEOTROCHUS pileus.
_Cap-shaped Land-trochus._
----
Order Phytophages. _Swains._ Tribe ----
SUB-GENERIC CHARACTER.
Shell pyramidical, each volution, reckoning from the base, gradually
diminishing and forming a conic spire, basal volution depressed, margin
of the outer lip reflected and entire.

SPECIFIC CHARACTER.
_Shell trochiform, smooth, generally banded with reddish and yellowish
bands: volutious convex._
Trochus Pileus. _Chemnetz. Pl. 122. f. 1046-7-8._
Helix pileus. _Dillwyn. p. 933. No. 106._
_Lister. Tab. 14. f. 11._

Although this shell, in artificial arrangements, may be very well placed
among the sub-divisions of _Helix_ or _Bulimus_, we feel persuaded that it
is, _naturally_, the type of a Sub-genus: we have no hesitation, therefore,
in recording it as such. Another species, sharply carinated,
semi-transparent, and of a milky whiteness, we discovered in Brazil: and we
are thus led to conclude that the habitat of _Geotrochus pileus_, which no
author has yet mentioned, may probably be Tropical America.
The figures of this species, given by Chemnitz and Born, represent it as
marked by several narrow bands of a rufous brown colour: but the variety
here delineated, has only one, of a deep purple; it is almost the only
specimen answering to this description, which we have yet seen: both
varieties are very rare, and much prized by collectors.
