Hab. Alabama River at Claiborne. Judge Tait. 



My Cabinet. 

 Diam. .25, Length .55 of an inch. 



Remarks. — With the M. Taitiana herein described, came two specimens of 

 this species, which differs from the Taitiana in the elevation of the spire, and 

 the form and size of the aperture. In the most perfect specimen, the columella 

 and base are purplish : The aperture is more than one-third the length of the 

 shell. The upper whorls are slightly carinate on their lower portion. 



Melania Kirtlandlina. Plate 5., Fig. 4. 



Testd IcBvi, acuto-conicd, sub-crassd, nitidd, corned; spird elevatd, prope apicem carinatd ; suturis 

 impressis; anfractibus novenis, convexiusculis ; aperturd parvd, ellipticd, albidd. 



Shell smooth, acutely conical, rather thick, shining, horn-coloured ; spire elevated, towards the apex 

 carinate ; sutures impressed ; whorls nine, rather convex ; aperture small, elliptical, whitish. 



Hab. Richmond, Indiana; Duck Creek, near Cincinnati; and Miami, 

 Ohio. T. G. Lea. Little Miami, Dr. Warder. 



My Cabinet, and Cabinets of T. G. Lea, P. H. Nicklin, and Dr. Warder. 

 Diam. .30, Length .87 of an inch. 



Remarks. — This is a finely-formed, graceful species, with an indistinct 

 carina on the lower part of the whorls, near the apex. The aperture is nearly 

 one-third the length of the shell. I name it after Professor Kirtland, of Poland, 

 Ohio.

Testd lavi, conoided, subtenui, nitidd, corned; spird decisd, ad apicem carinatd; suturis impressis , 

 anfractibus subconvexis ; aperturd parvd, ellipticd, inferne subangulatd, albidd.
