26 DESCRIPTION OF 
Hab. Alabama, KE. Foreman, M.D. My Cabinet, and Cabinets of Dr. Foreman, T. G. Lea, and J. 
Clark. Diam. .40, Length .64 of an inch. 
Remarks.—This shell is very remarkable for the cut in the superior part of the outer 
lip, very similar to some species of Pleurotoma. This cut extends nearly one-fifth round 
the whorl, leaving immediately below the suture an elevated ridge. ‘There are nearly 
three whorls of this specimen perfect, and the cicatrix shows the cut to have extended in 
due proportion thus far. The aperture is rather small, and rather more than one-third the 
length of the shell. On the spire there is a slight disposition to plication. The apex 
being eroded, the number of whorls is not certain, perhaps six. ‘This specimen has 
three revolving purple bands. 
For the first time we now observe in the Melaniana a species with a pleurotomose lip. 
In all its other characters it is a true Melania resembling most, perhaps, M. Vanuzemiana, 
herein described. A character so anomalous in this family, caused me to doubt the pro- 
priety of retaining it here. But the absence of the animal, and the fact that I have before 
me a new species, with the other characteristics of the genus Anculosa, having in a mi- 
nor degree this pleurotomose character, induces me merely to propose a name provision- 
ally for it. ‘The animal may be on examination different; should it prove so, it may then 
be called Schizostoma, Syila, to cut, Stéua, a mouth. 
Under the microscope may be observed, in this species, very minute undulating re- 
volving striz. 
Meania Orpiana. 
Testa striatd, pyramidatd, crassa, tenebroso-fuscd ; spird exsertd; suturis valde impressis; anfractibus planulatis ; 
apertura formam rhombi habente, parva, albidd. 
Shell striate, pyramidal, thick, dark brown; spire drawn out; sutures deeply impressed; whorls flattened; aperture rhom- 
bic, small, whitish. 
Hab. Alabama, KE, Foreman, M.D. My Cabinet, and Cabinets of Dr. Foreman, 'T. G. Lea, and J, 
Clark. Diam. .52, Length 1.25 of an inch. 
Remarks.—A single specimen only of this species is before me, and that unfortunately 
is decollate, in having lost, probably, four or five whorls: the four lower whorls are perfect. 
The outer lip is much curved, giving the aperture an auger-like appearance, and causing 
the channel to be much impressed. On the body whorl there are four rather distant ele- 
vated stri#, three of which are large: the whorls above exhibit two. The aperture is 
about one-fourth the length of the shell. This species resembles M. canahculata, (Say,) 
and M. annulifera, (Con.) It has not the channel of the former, and differs from the lat- 
ter, in having deeply impressed sutures in the form of the aperture, in the outer lip, and 
in the strie. I dedicate it to my old friend, George Ord, Esq. 
MELANIA BREVIS. 
Testd striatd, subcylindraced, subsolidd, luted; spird breviusculd; suturis impressis; anfractibus planulatis; columella 
superné incrassala; apertura ovata, alba. 
Shell striate, subcylindrical, somewhat solid, yellow; spire rather short; sutures impressed; whorls flattened; columella 
thickened above; aperture ovate, white.
