Shell narrowly umbilicated ; globosely depressed, of a dark yellowish color, sur- 
face somewhat shining, covered with oblique striæ, interrupted by numerous wavy 
lines and oblong blister-like wrinkles, hardly perceptible to the naked eye; whorls 
54, convex, striped by a single chestnut band, double margined by lighter ones; 
spire very little elevated, suture well impressed; lip simple, reflected, and nearly 
covering the umbilicus, its terminations approaching and joined by a thin callus ;

San Jacinto Valley, San Diego Co., California. 
A very depressed form, quite variable in size, some of the specimens not being 
more than half the size of the measurements given. It is lighter colored than any 
of the southern varieties of tudiculata except var. Binneyi.

I give a new figure of this species, 
Arionta intercisa, W. G. Binney. 
In “Zoe,” Vol. I. No. 11, January, 1891, p. 330, Mr. Hemphill describes 
these varieties of A. intercisa : — 
Var. minor. Smallest specimen, greatest diameter 18 mm., altitude 11 mm. 
Uniform light yellowish chestnut-color, with and without a band, and varies 
very much in form and elevation or depression of spire. 
Var. elegans. Uniform ashy buff-color, faintly banded, and variable in form. 
Var. nepos. Uniform ashy white; spire horn-color, variable in form and 
sculpturing. 
Var. albida. Uniform. milk-white, sometimes with a faint band at the 
periphery; sculpture nearly obsolete. 
In the same journal (p. 434) Mr. Hemphill thus describes several varieties 
of redimita, which species he refers, however, to Kelletti: — 
Var. castaneus. Uniform, polished, chestnut-color, darker band at the periph- 
ery, spire sprinkled with fine ashen specks. 
Var. hybrida. Uniform ash-white color, and a dark band at the periphery, 
flecked with transverse markings and specks of dark brown and light chestnut. 
Arionta ruficincta, Gass.

A new figure is given of this species, 
Arionta Kelletti, Fornns. 
Mr. Hemphill, in Terr. Moll. V., 3d Suppl., has thus described several 
varieties. I figure authentic specimens of each.
