instances there is an indistinct fifth band. The aperture is more than one-third the 

 length of the shell.

 parvum impressis ; anfraetibus superne planulatis, ultimo grandi; apertura submagna, rhornboidea, 

 intus tenebrosa ; labro acuto, vix sinuoso ; columella parum incurva, vix incrassata.

Hah. — Tennessee River, Dr. Spillman. 



My cabinet and cabinet of Dr. Spillman. 

 Diam. "38, Length "G8 inch. 



Remarks.— Only two specimens were received from Dr. Spillman, both much worn 

 at the apex. Two of the lower whorls only are perfect. The bands on both are 

 imperfect and obscure. They may be considered to be three, one being on the peri- 

 phery of the whorl. One is much darker in the interior than the other, and has a dark 

 purple mark at the base of the columella. It has very much the form of Melania 

 {Goniohasis) perfusca (nobis), but differs, in size, in aperture, and in carination. The 

 character of the upper whorls cannot be ascertained by these specimens, nor the pro- 

 portion of the aperture, but it must be nearly one half the length of the shell. 



GONIOBASIS RUBELLA. PL 38, fig. 191. - 



Testa carinata, subulata, subtenui, rubicunda, evittata; spira attenuata; suturis valde impressis; anfraetibus 

 octonis, subconvexis ; apertura parvissima, subrbomboidea, intiis vel albida vel rubida ; labro acuto, 

 sinuoso ; columella parum incurva et eontorta. 



Shell carinate, awl-shaped, rather thin, reddish, without bands ; spire attenuate ; 



sutures very much impressed ; whorls eight, somewhat convex ; aperture very small, 



subrhomboidal, whitish or reddish within ; outer lip acute, sinuous ; columella slightly 



bent in and twisted.

Hah. — Near Murphy, Cherokee county, North Carolinai, Prof. Christy. 



My cabinet and cabinets of Mr. Clark and Dr. Hartman. 

 Diam. -23, Length -G8 inch. 



Remarks. — I have eight specimens before me, sent some years since by my late 

 friend Mr. Clark, being part of the collection made by Prof. Christy. In form and 

 size this species is very near to Melania (Goniohasis) teres (nobis), but it differs in 

 being carinate, and having stria) which in all the specimens reach more than halfway
