84 DESCRIPTION OF NEW 



and perfect specimen, with four small purple bands and a tuberculous shoulder, the tuber- 

 cles being prolonged nearly into folds. Two others are indistinctly banded. Another 

 has a tuberculous shoulder, and is disposed to be granulate. From these varieties arises 

 the name given to it. The aperture is rather contracted, and about two-fifths the length 

 of the shell. 



Melania lugubris. PI. IX. Fig. 29. 



Testa Isevi, subacuto-conoided, subcrassa, tenebroso-fuscd ; spird sabelevatd; suturis late hnpressis; anfrac- 

 tibus planulatis ; aperturd parvd, rhomboidcd, intus cxruled, inferne angulatd. 



Shell smooth, rather acutely conical, rather thick, dark-brown ; spire rather elevated; sutures widely impressed; 

 whorls flattened; aperture small, rhomboidal, within bluish, angular below. 



Hab. Alabama. Major Le Conte. 



Cabinet of Major Le Conte. 

 Diam. .37, Length .85 of an inch. 



Remarks. — A single specimen only of this species was received by Major Le Conte. 

 There are no strong characters to separate it, but it is certainly different from any with 

 which I am acquainted. Like the canaliculata, Say, it is auger-shaped on the right 

 lip, but it is a much smaller shell, and without the sulcations of that species. There 

 is an angle in the middle of the whorl which causes the sutures to be rather wide and 

 marked. The apex being eroded, the number of whorls cannot be ascertained — probably 

 eight. The aperture is about one-third the length of the shell. 



Melania torta. PI. IX. Fig. 30. 



Testa hevi, claviformi, subcrassa, tcncbroso-fuscd : spird obtusd; suturis hnpressis; anfractibus convexis; 

 aperturd grande, cllipticd ; columella lorld. 



Shell smooth, club-shaped, rather thick, dark-brown; spire obtuse; sutures impressed; whorls convex; aperture 

 large, elliptical; columella twisted. 



Hab. Big Creek, Laurence County, Tennessee. J. Clark. 



My cabinet and cabinets of J. Clark and T. G. Lea. 

 Diam. .36, Length .73 of an inch. 



Remarks. — There were eight specimens of this species submitted to my examination by 

 Mr. Clark, of Cincinnati. In general outline and size it very closely resembles M. War- 

 deriana, (Nobis,) but differs from the specimens of that species which have come under my 

 notice, in not being carinate, and in having a more twisted columella. The apices of the 

 individuals now before me are slightly eroded, and the number of whorls may be seven or 

 eight. One of the specimens has small folds near the apex, with decussating stria). The 

 inside is bluish-white — one of the specimens having a brown mark at the columella. The 

 aperture is nearly one-half the length of the shell. Over the whole surface there are 

 small, irregular ridges. The body whorl is very long.
