Shell with umbilicus partially covered, thin, pale corneous, depressly orbicular, with an indistinct brown band; whorls 5 convex, the last descending; lip white, not thickened, reflected. I have seen but a solitary specimen of this species. The size corresponds nearly with _H. facta_, but the thinness of the shell, the color, the more rounded whorls, the deeper suture, and the thin, white, reflected lip, sufficiently characterize this as a distinct species. _Helix facta_ Newc. State Collection, Species 1099. H. testa obtecte rimata, depresso-orbiculari, solida, compacta, glabra, albida, fusco-rubro uni-zonata; anfr. 5 ad 5½ convexiusculi, ultimus descendens; sutura modice impressa; apertura ovalis; labro crasso, reflexo, flavido. Diam. maj. 0.42, min. 0.35 pol. Alt. 0.22 pol. _Hab._ Insul. “Santa Barbara,” et “San Nicolas.” Shell with perforation covered, depressed orbicular, solid, _compact_, smooth, whitish, zoned with a brownish red band; whorls 5 to 5½ somewhat convex, the last descending; suture slightly impressed; aperture oval; lip thick, reflected, yellowish. A sub-fossil variety measures 0.60 by 0.32 inches. Very numerous on Santa Barbara Island; less so on San Nicolas. This species differs so essentially from the ordinary type of California Helices as to suggest a tropical region as its original habitat. One character in common with many of our species may be noticed, viz.: the colored band cutting the body whorl, inclosed between two faint light colored cinctures. The shell has a little the aspect of _H. Rothi_ Pfr., from the Island of Syra, but is smaller, less elevated, and with a thick reflected yellow lip. _Helix Whitneyi_ Newc. State Collection, Species 1112. H. testa corneo-fumosa, sub-planulata, polita umbilico perspectivo; sutura bene impressa; apertura lunaris; labro simplici; anfr. 4. Diam. 0.20 pol. Alt. 0.10 pol. _Hab._ prope “Lake Taho,” Cal., in montibus “Sierra Nevada,” elevatione 6100 ped. Angl. Shell smoky horn color, nearly flat above, smooth, with a perspective umbilicus; suture well impressed; aperture lunate; lip simple; whorls four. In the umbilicus resembling _H. striatella_ Anthony, with a smooth surface and a dull, smoky hue. Only three specimens were found, under damp logs and bark along a mountain stream, together with _H. Breweri_, and _chersina_. _H. Breweri_ Newc. State Collection, Species 1113. H. testa discoidea, pallide-cornea, nitida, lucida; sutura sub-canaliculata, late umbilicata; anfr. 5. apertura lunaris; labro tenue simplici. Diam. 0.20 pol. Alt 0.10 pol. _Hab._ prope “Lake Taho,” Cal., et montibus septentrionalibus.
