NEW FRESH WATER AND LAND SHELLS. 23 
Hab. Coosa River, Alabama. Dr, Brumby. My Cabinet, and Cabinets of Dr. Griffith, Dr. Jay, Dr. 
Foreman, T. G, Lea, and J. Clark. Diam. .80, Length 1.05 of an inch. 
Remarks.—This is a very distinct species, being more angular than any I have seen. 
In the specimen before me, there are three irregular transverse impressions, two above 
the angle, and one immediately below. The strie are more distinct on the lower half of 
the whorl. The first three whorls are very dark. The aperture is nearly one-half the 
length of the shell, and quite angular at the base.*

PALUDINA COOSAENSIS. 
Testé subglobosd, tenui, pallida, sublevi, perforata; spird brevi; suturis valde impressis; anfractibus quinis, rotun- 
datis; aperturd magna, subrotundd, intus albidd.' 
Shell subglobose, thin, pale, rather smooth, perforate; spire short; sutures very much impressed ; whorls five, round; 
aperture large, nearly round, within whitish. 
Hab. Coosa River, Alabama. Dr. Brumby. My Cabinet, and Cabinets of Dr. Griffith and Dr. Fore- 
man. Diam. .58, Length .62 of an inch. 
Remarks.—This species is remarkable for its round whorls, its width and large deep 
sutures. ‘The superior part of the whorls is somewhat flattened. The colour is remark- 
ably pale, nearly white. The epidermis is very thin, and under the lens displays very 
minute, rather regular longitudinal strie crossed on the body whorl by obsolete striae. 
The aperture is nearly one-half the length of the shell. 
PALUDINA CYCLOSTOMATIFORMIS. 
Testa subcylindraced, subcrassd, pallido-corned, levi, perforata; spird exsertd, ad apicem rosea, obtusd; suturis valde 
impressis; anfractibus quinis, rotundatis; apertura parva, subrotundd, intus salmonis colore tinctd. 
Shell subcylindrical, rather thick, pale horn colour, smooth, imperforate; spire exserted, at the apex rose-coloured and 
obtuse; sutures very much impressed; whorls five, rounded; aperture small, nearly round, within salmon-coloured. 
Hab. Coosa River, Alabama. Dr. Brumby. My Cabinet, and Cabinets of Dr. Griffith, Dr. Jay, L. 
W. Sloat, and Dr. Foreman. Diam. .32, Length .82 of an inch. 
Remarks.—'This is a very remarkable species assuming very much the form of an ex- 
serted Cyclostoma. <A single, somewhat worn specimen only, was received. ‘The aperture 
is rather more than one-third the length of the shell. Its subcylindrical form is very re- 
markable.+ 
* ince the above was written, I have received more mature and perfect specimens. ‘They differ from the one described 
in being darker in the epidermis, and in having four purple broad bands, which are very distinct within the aperture. In 
these specimens, there is a series of indistinct tubercles above the periphery of the last whorl.
