ed at the periphery ;color opaque white with more or less numerous 

 very pale brown subtranslucent spiral hands, all or part of wh'ch 

 may be absent; usually there is a peripheral white band and be- 

 tween it and the suture one or two translucent bands of which the 

 anterior is most constant; from 2-4 narrower translucent bands 

 may exist in front of the periphery; the base is rounded, at first 

 minutely perforate, later imperforate and sealed by a reflection of 

 the pillar lip; aperture rounded, slightly oblique, with a solid 

 white, slightly reflected peristome, but no callus on the body; pil- 

 lar broad, short with a conspicuous callosity. Alt. of shell 15, of 

 aperture 6, lat. of shell 15.5, of aperture 7.5 mm.

"This species is an offshoot of E. levis Pfr., from which it 

 differs by its smaller, and much heavier shell, fewer whorls con- 

 spicuous peristome and narrower, fewer and less interrupted band- 

 ing of a paler tint."— Dull, 100, t 8, f 3. 



E. (MICEAKIONTA) GUADELUPIANA. 



"Shell small, thin, depressed, of a dark-brownish color with 

 a narrow reddish band, bordered on each side by a pale streak, 

 just above the periphery; spire little elevated, suture distinct; epi- 

 dermis strong, in well-developed specimens slightly microscopical- 

 ly hirsute; sculpture of well-marked incremental lines, stronger on 

 the spire, with occasional microscopic punctations; base more or 

 less fl ittened, the last whorl with the periphery somewhat above 

 the middle of the whorl, umbilicus narrow and deep; aperture sub- 

 circular, very oblique with a strong whitish reflection of the peris- 

 tome, the ends of the lip on the body approximated, throat with 

 the bands showing through. Alt. of shell 6, diam. 10.5, aperture 

 diani. 4 5 mm. 



"Guadelupe Island, off Lower California, in IN". Lat. about 

 29 degrees, Anthony, 189G; Snodgrass and Heller, 1899. 



"This very well-marked little species is nearest to E. Cata- 

 linae, but is well depressed, with a larger umbilicus and differently 

 shaped aperture. It seems to be tolerably abundant, though most 

 of the specimens received were defective." — Dall 101, t 8, f 14, 15,
