Hob. — Tennessee, Dr. Edgar, and President Lindsley. 



My cabinet. 

 Diam. -23, Length -57 inch. 



Remarks. — A single specimen was among a number of shells simply labelled, "Ten- 

 nessee." This is a well characterized little species, which cannot be confounded with 

 any I know. It has two obscure bands, one of which shows on the whorls of the spire, 

 which is covered with rather distant folds, which curve to the right. The spire em- 

 bellished with folds, and a colored band reminds one of some of the small Mitrce. The 

 aperture is nearly one half the length of the shell. 



Goniobasis crispa. PL 38, fig. 180. 



Testa plicata et transverse striata, fusifornii, subcrassa, luteola, crispata, evittata ; spira obtusa, ; suturis 

 irregulariter impressis ; anfractibus instar senis, convexiusculis ; apertura grandi, ovato-rbomboidea, 

 intiis albida ; labro acuto, vix sinuoso ; columella parum incurva et contorta. 



Shell folded and transversely striate, fusiform, rather thick, yellowish, crispate, 

 without bands ; spire obtuse ; sutures irregularly impressed ; whorls about six ; some- 

 what convex ; aperture large, ovately rhomboidal ; whitish within; outer lip acute, 

 scarcely sinuous ; columella slightly bent in and twisted.

Hob. — Florence, Alabama, Rev. G. White. 



My cabinet and cabinet of Mr. White. 

 Diam. -30, Length -62 inch. 



Remarks. — A single specimen only was found among the numerous shells kindly 

 sent to me some years since by Mr. White. The folds are rather close, well-defined, 

 and incline to the left, reaching half way down the body whorl, and are crossed by 

 transverse stride, which cover the whole surface, and cause the upper portion to be 

 clathrate. The aperture is nearly half the length of the shell. 



Goniobasis ornatella. PL 38, fig. 181. 



Testa plicata, fusiforrni, crassiuscula, luteo-cornea, vittata ; spira obtuso-conoidea ; suturis irregulater et
