FRESH WATER AND LAND SHELLS. 57 
Remarks.—This is a very distinct species, with a not uncommon form. The green 
colour is unusual. On the upper part of the whorl, and on the line of the suture there is a 
light or brownish band. The body whorl is rather suddenly enlarged in the middle, which 
gives it a slight gibbous appearance, and it is irregularly transversely striate. ‘The apex 
of each of the three specimens under my examination being eroded, the number of whorls 
cannot be exactly ascertained, but I think there must be about six. The aperture is quite 
one-half the length of the shell. It is allied to M. sordida, (Nobis,) in outline, but may 
easily be distinguished in colour and the gibbous swelling on the whorls. I name this 
after Mr. Safford, to whose kindness I owe this and some other fine specimens from 
Tennessee.

Shell smooth, inflated, almost round, very thick, dark-brown; spire very obtusely conical; sutures impressed; 
whorls a little convex; aperture very large and rounded, within either white or purple; columella incurved and 
thickened.

Remarks.—I have three specimens before me from Mr. Safford; two of them are pur- 
ple within and one white. None of them are perfect on the apex, but I presume that the 
number of whorls must be five. One of the specimens has four. In outline it is very 
much like M. inflata, (Nobis,) but it differs totally in the form of the columella. In that 
species the columella is twisted backwards, and makes an angular oblique channel—in 
the pinguis it is regularly curved, with scarcely a perceptible indentation in the place of 
a channel. The aperture is fully one-half the length of the shell.

Testa levi, parva, obtuso-conoided, gibbosd, subfusiformi, subtenui, virido-corned ; spira obtusa; suturis

Shell smooth, small, obtusely conical, gibbous, subfusiform, rather thin, greenish horn-colour; spire obtuse, 
sutures irregularly impressed; whorls five, somewhat convex; aperture large, elliptical, within double banded ; 
columella rubiginose, thickened, flattened, impressed and much curved.

Remarks.—This is a small, very remarkable species. ‘There is a slight depression 
above the middle of the whorl, which gives it a somewhat gibbous form. ‘The most un- 
usual character pertaining to this species is, however, the very flat2and impressed columella,
