FRESH WATER AND LAND SHELLS. 87 



Hab. Tuscaloosa, Alabama. 13. W. Budd, M. D. 



My cabinet and cabinet of Dr. Budd. 

 Diani. .27, Length .53 of an inch. 



Remarks. — The two specimens before me are, in form and size, the same. They differ 

 in one having two broad, purple bands, and the other being entirely without. On the 

 inferior part of the whorl one has five rather distinct stria', the other has these less dis- 

 tinct. The apex of each of these is eroded, and therefore the number of the whorls can- 

 not be ascertained. This species is closely allied to .)/. alveare, Conrad, but is a much 

 smaller shell, and in the two individuals before me there is no appearance of the 

 tubercles which usually exist on the carina of the lower whorl of that species. 



Melania Alexandrensis. PI. IX. Fig. 37. 



Testa Ixvi, subacuto-conoided, subtenui, tenebroso-corned ; spird mbelevata; suturis subimpressis ; anfrac- 

 tibus subplamUatis } aper turd par vd, subtrapezoided, intus albidd. 



Shell smooth, rather acutely conical, rather thin, dark horn-colour: spire rather elevated; sutures somewhat 

 impressed; whorls rather flattened; aperture small and somewhat trapezoidal; within whitish.

My cabinet and cabinet of Dr. Hale. 

 Diam. .22, Length .58 of an inch. 



Hi murks. — There were two only of this species which came from Dr. Dale. It closely 



resembles the Haleiana, herein described, but has a less elevated spire, and the aperture 



differs, in being somewhat auger-shaped, the outer lip being more sinuous. The apex of 



each being broken, the number of whorls cannot be ascertained. The aperture is rather 



nore than a fourth of the length of the shell. 



Melania ovoidea. PI. IX. Fig. 38. 



/'. ' ■ Uevi, ellipticd, subcra pird brevi; suturis irix impressis; anfractibus tenia, subconvexis; 



turd magna, subovaid, intus albidd. 



Shell smooth, elliptical, rather thick, horn-colour; spire short; sutures slightly impressed; whorls six, sliL r hil\ 

 convex; aperture large, nearly ovate, within while 



Hab. Alexandria, Louisiana. J. Hale. M.D. 



My cabinet and cabinet of Dr. Hale. 

 Diam. .2, Length .44 of an inch. 



Remarks. — A single specimen onh of this little species was found among the shelh 

 -'■ii' b\ Dr. Hale. It differs entirely from the othertwo species, and approaches Mr. Sa\'- 

 lep _ . but is -mailer, and has a proportionately larger aperture. The aperture is quite 

 one-half the length of the. shell. The columella is Bomewhat thickened on the superior 

 portion. In the specimen before me there are two broad, rather indistinct brown hands.
