VITRINA. (See below.) 

 Vitrina PfeilTeri. Newcomb. 

 Shell moderately depressed, smooth, shiuing, pellucid, greenish- white • 

 whorls 3, the last composing- most of the shell ; suture very finely mar- 

 Fro. 53. gined; aperture large, obliquely and roundedly ovate; lip 

 ^^^ thin, columella arched. Diameter S™'^' j axis, 2"^"^'. (New-

Vitrina P/ei/eri, Newcowb, Pioc. Cal. Acad. Nat. Sci., ii, 92 (18(51).— 

 Tryon, Am. Journ. Conch., ii, 244, pi. iii, fig. 3 (18G6).— W. G. Bixney, 

 L. & Fr.-W. Sh. i, 28, fig. 26 (1869) : Terr. Moll., v, 138. 



I have traced this species over all of California as far south as Fres- 

 no County ; in Nevada ; Colorado ; at St. George, Utah ; at Fort Win- 

 gate, New Mexico. It may therefore be said to inhabit both the Califor- 

 nia Province and the Central Region. It is, as usual in the genus, 

 found at high elevations. 



Like V. limpida it is variable in color. 



Jaw as usual in the genus. 



The specimen figured is authentic. 



The lingual membrane has over 50-1-50 teeth, with 10 perfect lat- 

 erals on each side. I have figured a central and lateral (Plate II, Fig. 

 A. Terr. Moll., V), and one extreme marginal. 



LIJflAX. (See below.) 

 JLiiiiax Hewstoni, J. G. Cooper. 

 Similar to L. Soicerbii (of England), the back being strongly carinate 

 even when fully extended, and higher than the front of the body; 

 mantle granulate- rugose, and with a groove, subollii)tic in outline, 

 above the level of the respiratory orifice, which is just behind the mid- 

 dle; color blackish- brown or deep bhick above, the sides paler, the 

 base of foot whitish. Length, 2^ iiicues or less ; height of body twice 

 the width of foot. 

 Internal plate oblong-oval, i inch long. Gardens in San Francisco.
