NEW MELANIDiE OF THE UNITED STATES. 303 



My cabinet and cabinet of Dr. Spillman. 

 Diam. -39, Length -94 inch. 



Remarks. — Only three specimens were received from Dr. Spill man, two of which 

 are little more than half grown. In outline it is near to Melania (Goniobasis) graci- 

 lis (nobis), but it is more fusiform, rather larger and not so thick. The color is very 

 nearly the same. There is a slight disposition to angulation on the periphery of the 

 whorls. The aperture is about four-tenths the length of the shell. I dedicate this 

 species to Dr. Spillman, who has done so much to elucidate the natural history of the 

 Southern States.

Testa laevi, obtuso-conica, subtenui, flava, trivittata ; spira obtuso-conica ; suturis valdc iinpressis ; anfrac- 

 tibus instar senis, convexiusculis ; apertura parviuseula, ovata, intus alba et trivittata; labro acuto, 

 paruin sinuoso ; columella incurva, incrassata.

Hob. — Benton County ? N. W. Alabama, G. Hallenbeck. 



My cabinet and cabinet of Mr. Hallenbeck. 

 Diam. -35, Length "88 inch. 



Remarks. — A single specimen, only, of this pretty species, was sent to me by Mr. 

 Hallenbeck. It cannot be confounded with any other species known to me. It re- 

 minds one of Melania grata, Anth., but it has a rounder base, is not fusiform, and 

 has but three bands, which are well marked inside and out. The three bands are 

 equidistant and of equal size. The upper part of the columella is thickened, and in 

 this specimen the color of the upper band is extended over part of this callus. The 

 aperture is rather more than one-third the length of the shell. 



Goniobasis Anthonti. PL 37, fig. 140. 



Testa laavi, obtuso-conica, subtenui, micanti, tenebroso-castanea, evittata ; spira obtusa ; suturis impressis ; 

 anfractibus instar senis, convexiusculis; apertura subgrandi, elongato-rhombica, intus fuscesceute; 

 labro acuto, ad marginum albido et parum incrassato ; columella incurva et valde contorta. 



Shell smooth, obtusely conical, rather thin, shining, dark chestnut brown, with- 

 out bands ; spire obtuse ; sutures impressed ; whorls about six, somewhat convex ; 

 aperture rather large, elongately rhombic, brownish within ; outer lip acute, white
