94 DESCRIPTION OF NEW 



Schizostoma Buddii. PI. IX. Fig. 53. 



Testa striata, subfusiformi, crassd, tenebroso-comed ; spira obtuso-conicd ; suturis irregulariter impressis; 

 anfractibus senis, subinflatis; fissura parvd, obliqud; aperturd magna, rhomboided, intus albidd; columella 



superne callosd. 



Shell striate, subfusiform, thick, dark horn-coloured; spire obtusely conical; sutures irregularly impressed; 

 whorls sis, rather inflated; fissure small, oblique; aperture large, rhomboidal, whitish within; columella thickened 

 above. 



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



My cabinet and cabinet of Dr. Budd. 

 Diam. .47, Length .83 of an inch. 



Remarks. — This is a robust shell, being thicker and heavier than any other species 

 of this genus which I have observed. The aperture is nearly one-half the length of the 

 shell. Two specimens were sent together by Dr. Budd, presuming they were the same. 

 One, however, which is not quite a mature shell, has little or no fissure. The other, from 

 which the description is made, has a wide but short fissure, and the margin of it opens 

 obliquely. 



Schizostoma Babylonicum. PI. IX. Fig. 54. 



Testa striata, subfusiformi, subcrassd, castanea; spird obtuso-conicd ; suturis impressis; anfractibus planu- 

 latis; fissurd parvd; aperturd magna, elliplicd, intus subcarned; columella Ixvi, ad basim angulatd, superne. 

 incrassatd. 



Shell striate, somewhat fusiform, rather thick, chestnut-coloured ; spire obtusely conical; sutures impressed; 

 whorls flattened; fissure small; aperture large, elliptical, somewhat flesh-coloured within; columella smooth, 

 angular at the base, thickened above. 



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



Cabinet of Dr. Budd. 

 Diam. .48, Length 1 inch. 



Remarks. — A single specimen only of this species was submitted to me. It differs 

 from the other described species in being angular at the superior portion of the whorl 

 along the lower margin of the fissure, making quite a shoulder, and giving it the Baby- 

 Ionic appearance. The fissure is wide, but not deep. The apex being much eroded, the 

 number of whorls could not be ascertained. The aperture is nearly half the length of 

 the shell. The deposit on the columella in this individual does not cover the perforation. 

 In others, this may differ. The outer lip is quite patulous. 



Schizostoma constrictum. PI. IX. Fig. 55. 



Testa lievi, subfusiformi, subtenui, luteo-corned ; spira obtusd; suturis impressis ; anfractibus coarctatis; 

 fissura submagnd, subobliqua : aperturd magnd, ellipticd, intus albidd : columella Isevi, ad basim subangulatd. 



Shell smooth, somewhat fusiform, rather thin, yellowish horn-colour; spire obtuse; sutures impressed; whorls 

 constricted; fissure rather large, somewhat oblique; aperture large, elliptical, whitish within; columella smooth, 

 subangular at the base.
