Remarks. — Some half dozen specimens were among the shells received from Prof. 

 Tuomey obtained during his geological survey. This is rather a small species be- 

 tween Melania {Goniobasis) costulata (nobis), and Melania (Go?iiobasis) Edgariana 

 (nobis). It has a less number of folds than the former, and about the same number as 

 the latter, but these folds differ in not being so much raised and protruded above as 

 in Edrjariana, nor is the spire so high. The interior is usually white, sometimes 

 double-banded, and one of the specimens is dark-brown. The aperture is nearly 

 half the length of the shell.

Remarlcs. — I have eight specimens before me of this modest little species. They 

 were taken by Prof. Tuomey during his Geological Survey of Alabama many years 

 since. The folds are not on the body whorl ; they incline to the left. It is allied to 

 Melania {Goniobasis) acuta (nobis), but is not so small nor so pointed, and it is more 

 of a horn-color. The aperture is about one-third the length of the shell.
