NEW FRESH WATER AND LAND SHELLS. 3 
shorter than that from Nubia, but it is not so turbinate as this species, nor do they agree 
in the form of their apertures nor in the markings. On the lower whorl the turbinata is 
brown. The superior whorls are obliquely marked with brown bands, which are broken up 
into spots on the penultimate whorl, and become darker. In the form of the mouth it ap- 
proaches very closely to the genus Budimus. 
ACHATINA STRIATA.

nis, subconvexis; apertura parvd, ellipticd; columella incurvatd.

Shell somewhat cylindrical, horn colour, thin, longitudinally an 
rather convex; aperture small, elliptical; columella incurved.

of an inch. 
Remarks.—This is a beautiful little species, rather larger than the folliculus, Lam. In 
form it resembles Bulimus octoneus, Rang. (Achatina,) but is not quite so large. Its minute 
and close ribs distinguish it at once, as the octoneus is perfectly smooth. The aperture is 
about one-fourth the length of the shell, and the striw do not extend below the middle part 
of the lower whorl. 
GENUS SUCCINEA. (Drararnavn.) 
Hight species of Swccinea have been described as inhabiting the United States. I now 
propose to add nine to that number, besides three from the West Indies and Hast Indies.

Hab. Java? My Cabinet. Diam. .32, Length .42 of an inch. 
Remarks.—I procured a single specimen of this graceful and delicate species in New 
York of a dealer some years since. He informed me that it came from the collection of 
Mr. Shillaber, which was brought from Batavia. In ‘form it resembles S. Nuttalliana 
herein described, but it is a much more exserted species and larger. ‘The whorls below 
the sutures are impressed. The strie are larger and more distant near to the aperture. 
A small portion only of the epidermis remains, and that is dark. The point of the spire 
is fractured, and therefore the number of the whorls is not mentioned. I suppose, when 
perfect there will be found three. ‘The want of the usual transparency may be occasioned 
by the specimen not being fresh. -
