distinct enough to be separated. The largest of the Sargent 
shells that I have seen measures, gr. diam. 184, less. 164, alt. 
7 mm., whorls 5%, umbilicus less than one-third of the diameter 
of the shell. A single shell collected by H. H. Smith in the 
same locality measures 19? * 84 mm., whorls 6. 
In cumberlandiana there is a single row of small, faint, squar- 
ish, brown markings just below the carina on the base; in the 
Woodville shells these spots are larger and much darker. Figs.

Differs from the type by its larger size, much finer and flatter 
ribs and more convex shape; carina white, sharp, but less 
pinched than in the type and the ribs on the carina much lower 
and less accentuated. Ground color lighter than in the Sewanee 
shells and markings darker. There is a single row of squarish 
flames just below the carina on the base. Umbilicus about one- 
fourth the diameter of the shell.

Collected by H. H. Smith in 1905 on Vincent Mountain, 
near Gurley and on Smithers Mountain, 5 miles N. W. of 
Huntsville, both in Madison Co., Ala. Types No. 7132 of my 
collection (Gurley) and paratypes in the collections of the 
Academy of Natural Sciences, Philadelphia, and Dr. Bryant 
Walker, Detroit, Mich. 
P. CUMBERLANDIANA COLUMBA n. var. Pl. I, Fig. 5. Dove, 
Tenn. 
Like the type in sculpture, color and markings, but not 
pinched at the carina. Heavily ribbed above and on the carina, 
but below the ribs are much finer, about 2.1. There is a single 
row of chocolate brown, diagonal markings immediately below 
the carina. 
Gr. diam. 184, less. 164, alt. 8 mm. Aper. 74 X 7 mm.
