Zonites Shepardi, Hrmraıte. 
Shell umbilicated, very small, depressed ; whorls 3 or 34, shining, transparent, 
smooth, somewhat flattened; spire scarcely elevated above the body whorl; aper- 
ture oblique, oval; peristome simple, acute, its ends hardly approaching ; suture 
well impressed; umbilicus pervious, and moderately large for so small a shell. 
Great diameter, 2 mm. Height, 1 mm. 
Santa Catalina Island, California. 
This little shell belongs to the planulate forms, and somewhat resembles a minute 
Z. Whitneyi. 
I dedicate it to Miss Ida Shepard in recognition of her active services among the 
mollusks of Long Beach, Cal., where she resides. 
The above is Mr. Hemphill’s description. 
Zonites Lawæ. 
Shell small, umbilicated, globose, flatter below, shining, light horn-colored, 
marked with coarse wrinkles of growth; spire rounded; whorls 8, gradually 
increasing, slightly convex, the last excavated below around the umbilicus ; 
aperture oblique, rounded; peristome simple, acute, thickened with callus 
within. Greater diameter 9,mm., lesser 7 mm.; height 4 mm. 
Zonites placentula, part, W. G. Binney, formerly, Terr. Moll. U.S. V., p. 124, Fig. 
44; Plate III. Fig. L (dentition). 
Zonites Lawi, W. G. Binney, Suppl. to Vol. V. p. 142; Plate II. Fig. E (also, 
Ann. N. Y. Ac. Sci., Vol. I., Plate XV. Fig. E, as undetermined). 
Mountains of Tennessee (Miss Law); a species of the Cumberland Subregion, 
Readily distinguished from placentula by its larger size, higher rounded spire, 
greater number of whorls, and more widely excavated umbilical region. 
Jaw as nsual in the genus. 
Lingual membrane (Vol. V. Plate III. Fig. L, as placentula) with 25-1-25 
teeth; three laterals and one transition tooth. 
Zonites Caroliniensis, COCKERELL. 
Plate III. Fig. 7%. 
Among the specimens of Zonites sculptilis collected in the mountains of 
North Carolina are many which differ from the type widely enough to be 
considered a distinct species. Mr. Cockerell suggests for it the name Caro- 
linensis, thus describing it : — 
This species differs from sculptilis in its fewer whorls, straighter columellar 
margin, less iunate aperture, fewer radiating strie, and other points. It is figured 
as sculptilis in Manual of American Land Shells, Fig. 231.
