28 DESCRIPTION OF 
MELANIA PRODUCTA. 
Testa plicatd, subfusiformi, subtenui, corned; spird obtuso-conicd; suluris impressis; anfractibus octonis, planulatis; 
apertura ellipticd, albidd. ‘ 
Shell folded, subfusiform, rather thin, horn-coloured; spire obtusely conical; sutures impressed; whorls eight, flattened; 
aperture elliptical, whitish. 
Hab, Tennessee. EK. Foreman, M. D, My Cabinet, and Cabinet of Dr. Foreman. Diam, .57, Length 
-70 of an inch. 
Remarks.—This species has rather distant folds on the first six whorls, and a disposi- 
tion to tuberculation on the middle of the lower whorl, the superior part being disposed 
to be striate. The base of the columella is twisted, and the channel well impressed. 
The aperture is quite one-half the length of the shell. 
MELANIA CURVATA. 
Testa obtuso-carinatd, subpyramidatd, subcrassd, tenebroso-corned; spird subelevatd; suturis impressis; anfractibus 
octonis, convexis; apertura parva, curvatd, albidd. 
Shell obtusely carinate, somewhat pyramidal, rather thick, dark horn colour; spire somewhat elevated ; sutures im- 
pressed; whorls eight, convex; aperture small, curved, whitish. 
Hab. Tennessee. E. Foreman, M. D. My Cabinet, and Cabinet of Dr. Foreman. Diam, .40, Length 
-73 of an inch. 
Remarks.—The two specimens before me vary very little in all their characters. This 
is a very distinct species, resembling more, perhaps, M. conica (Say) than any other. The 
whorls are close, and about the middle are placed two or three obscure carine, which 
cause a slightly impressed channel. The aperture is small, being a little more than one- 
third the length of the shell. ‘The outer lip is sharp and very much curved, causing the 
base of the columella to be twisted. In one of the specimens an obscure band near the 
base in the interior may be observed. 
MELANIA EXPANSA. 
Testa levi, subfusiformi, subcrassi, luteold; spird obtuso-conicd; suturis subimpressis; anfractibus quinis, subcon- 
vexis; aperturi magna, expansd, albidd. 
Shell smooth, somewhat fusiform, rather thick, yellowish; spire obtusely conical; sutures somewhat impressed; whorls 
five, slightly convex; aperture large, expanded, whitish. 
Hab. Alabama. KH, Foreman, M.D. Cabinet of Dr. Foreman. Diam. .43, Length .63 of an inch. 
Remarks.—A solitary specimen of this was among the shells sent by Dr. Foreman. In 
form it resembles M. vartalils, (nobis,) but may be distinguished from that species in 
being larger, and having a larger proportionate aperture, which is more expanded. The 
aperture is full one-half the length of the shell. The specimen under examination has 
four bands, and the yellow epidermis is nearly covered with a deposite of the oxide of iron. 
ANCULOSA INCISA. 
Testd levi, ovato-gibbosd, crassd, luteo-fuscd; spird brevis; anfractibus quaternis, planulatis; columelld superne in- 
crassatd; aperturd magna, ovatd, alba. 
Shell smooth, ovately gibbous, thick, yellowish brown; spire short; whorls four, flattened; columella thickened above; 
aperture large, ovate, white. 
Hab. Alabama. EE. Foreman, M. D. My Cabinet, and Cabinets of Dr. Foreman, T. G. Lea, and J. 
Clark. Diam. .44, Length .64 of an inch.
