jj a l K — Coosa River, Alabama, E. R. Showalter, M. D. 



My cabinet and cabinet of Dr. Showalter. 

 Diam. -37, Length -89 inch. 



Remarks. — A species very closely allied to Melania (Goniobasis) Alabamcnsis, 



(nobis), but it may be distinguished by its being smaller, more constricted, and being 



slightly more cylindrical. The bands are smaller and not quite so well expressed. 



When I received the first specimen, I considered it a small variety of Alabamemis, 



but having received others from Dr. Showalter, I cannot but consider it a distinct 



species inosculating on the other. The aperture is about one-third the length of the 



shell. 



Goniobasis Beumbyi. PL 37, fig. 127. 



Testa Isevi, attenuate, subtenui, cinerea, quadrivittata ; spira attenuata, ad apiccm carinata ; suturis valde 

 impressis; anfractibus instar octonis, convexiusculis ; apertura parva, subrhomboidea, intiis albida 

 et quadrivittata ; labro acuto ; columella inflecta, ad basim obtuse angulata. 



Shell smooth, attenuate, rather thin, ash-grey, four-banded ; spire drawn out, cari- 

 nate at the apex ; sutures very much impressed ; whorls about eight, slightly con- 

 vex ; aperture small, subrhomboidal, whitish and four-banded within ; outer lip 

 acute ; columella bent in, obtusely angular at base.

Hah. — Alabama, Prof. Brumby. 



My cabinet. 

 Diam. -32, Length -74 inch. 



RemarJcs. — Two specimens were sent to me among other species, by the late Prof. 

 Brumby, of Columbia, South Carolina. One is but little more than half grown, and 

 is more perfect in the epidermis and in the aperture. It is'very closely allied to 

 Melania (Goniobasis) Kirtlandiana, (nobis), but it is more attenuate and has bands
