A.NCULOSA TINTINNABILIM. PI. IX. Fig. 51. 



Testa hevi, obtuso-conicd, campanulatd, fasciatd, percrassd, luted; spird brevi; suturis impressis} anfrac- 

 tibus qtnnis, impressis: aperlura rotunda, Stibgrandi; columella percrassd, superni callosd. 



Shell smooth, obtusely conical, bell-shaped, banded, very thick, yellow; spire short; sutures impressed; whorls 

 five, impressed; aperture rather large, round; columella very thick, callous above. 



Hab. Tennessee — E. Foreman, M. D. Tuscaloosa, Alabama — B. W. Budd, M. D. 



My cabinet and cabinets of Dr. Foreman ;md Dr. Budd. 



Diam. .48, Length .70 of an inch. 



Remarks. — The peculiar, constricted lower whorl, giving a campanulate form to this 

 shell, will distinguish it at once from other species. Six specimens before me are all 

 yellow, with broad, brown bands. A single specimen is perfect enough in the spire to 

 make out five whorls. Two of the specimens are white on the columella, and four are 

 tinted with brown. The outline is very remarkable, in its campanulate form. The 

 mouth, in the perfect specimen, is about two-thirds the length of the shell. 



SCHIZOSTOMA* PAGODA. PI. IX. Fig. 52. 



Testa carinatd, conicd, subcrassd, tenebroso-comed ; spird sitboblusd; suturis valdi impressis; unfractibus 

 senis : fissurd parvd } aperturd eflipticd, intus albidd; columella Ixvi. 



Shell carinate, conical, rather thick, dark horn-colour; spire rather short; sutures very much impressed; whorls 

 six; fissure small ; aperture elliptical, within whitish ; columella smooth. 



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

 My cabinet and cabinet of Dr. Budd. 

 Diam. .35, Length .75 of an inch. 



Remarks. — Three of this interesting species arc before me. They are very distinct, 

 i ml may easily be known by the carina being very acute on the superior whorls, present- 

 ing the appearance of a Chinese pagoda. The lower whorl is slightly and irregular!) 

 striate. The fissure is not deep, but rather wide, being about one-fifth the length of the 

 whorl. The columella at the base is rather angular. The aperture is rather more than 

 one-third the length of the shell. 



■ In a paper read before the society December 10, 1842, I described two species belonging to the Melanianx, 

 with the pleurotomose character of a fis.surc in the outer lip. Tor one I proposed the name of Mclania excita, 

 the other . I </, and presuming that the shells bearing this characteristic, so remarkable in a Melamon, 



would require to be placed in a new genus, I then proposed the name <>t Schizomania. Since then, five or six 

 other species have been observed) and tin- genus may lie thus characterized: 



Testa if I mnica vel fusiformis. Labrum tuperne Jissurd. Jlpcrtura ovatu. Columella hevis, incurva. 

 Operculum 



\ o operculum has come under my notice, but I can scarcely doubt that it will be found lo be horny, ami t.j 

 resemble, in other respects, that of Melania.
