Description. — Shell striate, fusiform, thiclv, yellowisli; spire ob- 

 tuse ; sutures rather impressed ; whorls six, rather convex ; aperture 

 elliptical, large, angular at the base, within 

 white. 

 Habitat. — Coosa River, Alabama. 

 Diameter, -CO; length, -91 of an inch. 

 Observations. — A single specimen only of 

 1^ this fine species was obtained by Dr. Griffith. 

 It presents four rather distant, large, re- 

 volving striaj on the body-whorl and two 

 on the next. In other specimens these may 

 be found more numerous, or entirely want- 

 ing.* The aperture is nearly half the 

 length of the shell. In form and size, it 

 very closely agrees with 31. impressa herein 

 described. — Lea. 



Dr. Ja}' published merely a name 

 and figure of lii.s species, without de- 

 scription. The figure 613 represents 

 a copy of it. 612 represents Mr. Loa's figure of rohusta and 

 611 is from a splendid specimen from Coosa River, while 614 

 represents a younger sliell. 



The following description was drawn up from an immature 

 specimen ; we present a figure from the type : — 



Melania tceniolata. — Shell conic, ovate, striate, thick; spire ele- 

 vated, but not acute, composed of 6-7 nearly flat whorls ; sutures 

 not distinct; aperture subrhombic, small, banded within; columella 

 indented, callous at its lower portion, and with a small, but distinct, 

 sinus at base.

*In specimens subsequently received, the strim were found to differ but little.
