NEW FRESH WATER AND LAND SHELLS. 25 
MELANIA VANUXEMIANA.* 
Testa striatd, obtuso-conicd, solidd, luteold, fasciatd; spird breviusculd; suturis impressis; anfractibus senis, subcon- 
vexis; columella superné incrassatd; apertura ovata, alba. 
Shell striate, obtusely conical, solid, yellowish, banded ; spire rather short; sutures impressed; whorls six, somewhat 
convex; columella thickened above; aperture ovate, white. 
Hab. Alabama, E. Foreman, M. D. Cabinet of Dr. Foreman. Diam. ,42, Length, .73 of an inch. 
Remarks.—A very pretty symmetrical species, having the mouth rather more than one- 
third the length of the shell. A single specimen only is before me. It has five nearly 
equidistant coarse strie, and four purple bands. It is somewhat like M. ovalis, herein 
described, but has a wider aperture, and a higher spire. I name it after my friend, Prof. 
Vanuxem. 
MELANIA OVALIS. 
Testa striatd, fusiformi, solidd, luted, fasciatd ; suturis valde impressis; anfractibus senis, subconvewis; apertura 
ovatd, constrictd, intus albidd. 
Shell striate, fusiform, solid, yellow, banded; sutures much impressed; whorls six, rather convex; aperture oval, nar- 
row, whitish within. 
Hab. Alabama. E. Foreman, M. D. My Cabinet, and Cabinets of Dr, Foreman, T. G. Lea, and J. 
Clark. Diam, .40, Length .62 of an inch. 
Remarks.—A. number of specimens were kindly sent by Dr. Foreman for my inspec- 
tion, several of which are young, exhibiting on the first two or three whorls very distinct 
folds. 'Those of the larger specimens are worn off. The mature specimens are re- 
markable for their irregularly elliptical form, generally having transverse strie over the 
whole surface. The aperture is very regularly ovate, fully the half of the length of 
the shell. 
Me ania Haystana. 
Testa striata, subcylindraced, solidd, luteo-fuscd; spird subelevatd; suturis impressis; anfractibus planulatis; aper- 
turd parvd, ellipticd. 
Shell striate, subcylindrical, solid, yellowish brown; spire rather elevated; sutures impressed ; whorls flattened; aper- 
ture small, elliptical. 
Hab. Alabama. KE. Foreman, M. D. My Cabinet, and Cabinets of Dr, Foreman, T. G. Lea, and J. 
Clark. Diam. .43, Length .90 of an inch. 
Remarks.—Dr. Foreman submitted many specimens of this species to my examination, 
and I find them differing very much in form and colour. Some individuals are so full of 
dark purple bands as to give them a dark hue; others are devoid of bands entirely, and are 
yellowish. ‘The aperture is contracted, and about one-third the length of the shell. The 
transverse raised striz, in some, cover nearly all the whorls, while others are almost or en- 
tirely free from them. In general outline it is allied to M. picta, (nobis,) all the speci- 
mens being more or less eroded at the beaks. Iam unable to state the number of whorls, 
but believe them to be eight or nine. I dedicate this species to my friend Isaac Hays, 
M. D. 
MELANIA EXCISA. 
Testa striat, subfusiformi, subcrassd, luteold ; spird ovato-conicd; suturis impressis; anfractibus planulatis; aper- 
turd supernd excisd, parvd, elliptica, alba. 
Shell striate, subfusiform, rather thick, yellowish; spire ovately conical; sutures impressed ; whorls flattened; aperture 
cut out above, small, elliptical, white.
