Eulima rutila Carpenter, Rept. Brit. Ass. Adv. Sci. (1863) 1864, p. 659; Proc. 

 Gala. Acad. Nat. Sci., vol. 3, 1865, p. 221. 



Shell of medium size, elongate-conic, slender, straight, surface 

 polished, glassy without perceptible sculpture, excepting irregularly 

 distributed varices. Whorls appressod at the summit to such an 

 extent that the suture is scarcely perceptible; the basal portion of the 

 preceding whorls, shining through the substance of the succeeding 

 turns as a false suture; the true suture appearing about one-third 

 of the way between the summit and the false suture above the latter. 

 Periphery of the last whorl rounded, base sloping in such a way as to 

 lend the left outhne a somewhat flattened appearance. Aperture 

 large, oval; posterior angle acute; outer hp decidedly protracted 

 between the base and the posterior angle, forming a clawhke exten- 

 sion; inner hp short, moderately stout, somewhat curved, reflected 

 over and appressed to the base; parietal wall covered with a mod- 

 erately thick callus.

 California; it has 13 whorls and measures — ^length, 6.8 mm.; diameter, 

 1.9 mm,
