FRESH WATER AND LAND SHELLS. 95 



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



Cabinet of Dr. Budd. 

 Diam. .13, Length .75 of an inch. 



Remarks. — A single specimen only of this species was among the shells submitted to 

 me by Dr. Budd. It differs from those I have seen in having a rather broad channel 

 impressed immediately above the centre of the whorl. This character may, however, 

 differ in other individuals. The fissure is rather wide, but not deep. The apex being 

 eroded, the number of whorls could not be ascertained. The aperture is about one-half 

 the length of the shell. There is no appearance of bands about this specimen. 



SciUZOSTOMA FUNICULATUM. PI. IX. Fig. 56. 



Testa striata, cllipticd, subcrassa, castaned ; spird obtusd; suturis valde imprcssis; anfractibus convexis: 

 ftssnrd submagnd, obliqud; aperturd magna, ellipticd; columella superni callosd. 



Shell striate, elliptical, rather thick, chestnut-coloured; spire obtuse; sutures much impressed; whorls convex; 

 fissure rather large, oblique; aperture large, elliptical; columella thickened above. 



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



Cabinet of Dr. Budd. 

 Diam. .4, Length .66 of an inch. 



Remarks. — A single specimen only was obtained by Dr. Budd of this species. It is 

 short, stout, and almost subrotund. It has two elevated, cord-like lines, revolving on the 

 whorls. One immediately under the suture, the pther below that again. The aperture 

 is more than half the length of the shell. The apex is so much eroded as to prevent the 

 number of whorls being ascertained. There are about six.

ScHIZOSTOMA LACINIATUH. PI. IX. Fig. 57. 



' ' '. obluso-eonicd, subcrassa, fasciald, luteo-corned ; spird obtusd; suturis exaratis; anfractibus con- 



vexis; fissurd profunda } aperturd ellipticd, intus albidd ; adumilld l.rvi, superni incrassatd. 



Shell smooth, obtusely conical, rather thick, banded, yellowish horn-colour; spire obtuse; sutures excavated; 

 whorls convex; fissure deep; aperture elliptical, whitish within; columella smooth, thickened above. 



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



Cabinet of Dr. Budd. 

 Diam. .25, Length .45 of an inch. 



Remarks. — This is the smallest species I have seen. The mouth and fissure of this 

 specimen are perfect, but the apex is much eroded, and the number of whorls cannot 

 therefore be ascertained. There are four bands von distinct!} marked on the inside. 

 The aperture appear- t<> be about one-half the length of the shell. The fissure is very 

 narrow and remarkably deep, extending nearlj one-fourth round the whorl. The cicatrix 

 along the suture is of a lighter colour. The marks of growth are distinct, and give a 

 laciniate appearance.
