GONIOBASIS. 295 



Observations. — A single specimen only, and that imperfect, is 

 before me. The body-whorl has seven or eight distinctly marked 

 striae. On the penultimate there are three, and these give a sulcata 

 appearance to the shell. — Lea. 



When perfect specimens are obtained this shell may be 

 found to be a species of Pleurocera instead of Goniobasis,

Description. — Shell striate, cylindrical, rather thin, horn-color; 

 spire attenuated ; sutures impressed ; whorls flattened ; aperture 

 small, elliptical, within whitish. 



Habitat. — Tennessee. 



Diameter, -32 of an inch; length, 1-07 inches. 



Observations. — I have two specimens before me, both of which have 

 seventeen revolving strife on the lower whorl. They have also j,j ->, 

 a single small baud immediately below the middle of the body- 

 whorl, which is hidden on the superior whorls. Each of the 

 specimens under examination has the apex bi'oken, but I pre- 

 sume the number of whorls may reach to ten. Eight may be 

 counted in one of these. Dr. Budd mentions, in a note, that 

 "out of six, five have a band." The aperture is about one- 

 fourth the length of the shell. This species is nearly allied 

 to the striate variety of Mr. Say's M. Vir/jinica, which he called multi- 

 striata (multilineata, G. W. T., Jr.). The Buddii may be distinguished 

 by its being flattened on the whorls, in being more angular on the 

 superior part of the whorls, and in being more attenuate. — Lea. 



Figured from Mr. Lea's plate. This shell is so very closely 

 allied to Virginica that Dr. Bret has placed it in the synonymy 

 of that species.
