MELANIA AURICUL.EF0RMIS. PI. IX. Fig. 39. 



Testa Ixvi, elliplicd, subtenui, luted; spird depressd ; suturis impressis; anfractibus senis, subconvexis : 

 aperturd elongatd, contractu, ad basim rotundatd, intus albidd. 



Shell smooth, elliptical, rather thin, yellow; spire depressed ; sutures impressed; whorls six, slightly convex : 

 aperture elongate, contracted, at the base rounded, within whitish. 



Hab. Tuscaloosa, Alabama. B. W. Butkl, M. D. 



Cabinet of Dr. Budd. 

 Diam. .24, Length .45 of an inch. 



Remarks. — This species has very much the aspect of an Auricula. It is a very regu- 

 larly formed and pretty shell, with a smooth, yellow, polished, epidermis. The aperture 

 is about two-thirds the length of the shell, regularly rounded below and angular above, 

 where there is a good deal of nacreous matter deposited. 



Melania carino-costata. PI. IX. Fig. 40. 



Testa p/icatd, carinatd, conoided, subtenui, vel luted vel castaned; spird subelevatd; suturis sulcatis; 

 anfractibus p/unulatis ; aperturd parvd, ellipticd; columella Ixvi. 



Shell plicate, carinate, conical, rather thin, yellow or chestnut-coloured; spire somewhat elevated; sutures sul- 

 cate; whorls flattened; aperture small, elliptical; columella smooth. 



Hab. Alabama— Major Le Conte. Tennessee— B. W. Budd, M. D. 



My cabinet and cabinets of Major Le Conte and Dr. Budd. 

 Diam. .3G, Length .98 of an inch. 



Remarks. — This is a species not easily confounded with any other known to me. The 

 character of the ribs or folds is peculiar; they being arrested near the sutures by an ab- 

 rupt carina, which has a smaller parallel one between it. The folds and the carinas are 

 conspicuous, being perfectly pronounced. Two of the six specimens before me are of a 

 dark chestnut-brown, with the nacre of the interior quite rufous. One is more horn- 

 coloured, having four bands, and the nacre whitish. The three others, all from Dr. Budd, 

 are wax-yellow, the ribs less expressed, and the interior yellowish. The apex of each 

 being broken, the number of whorls cannot be determined — I should think there were 

 about eight. The inferior part of the whorl is smooth. The aperture is rather more 

 than one-third the length of the shell.
