Species 563. (Mus. Cuming.) 



Helix ciilorozoxa. TIel. testa suhampliter umbilicatd, 

 orlikulari, stibdepressa, stibtm convexd, aliu, cadaneo 

 late trifaacialu ; spird oMusd ; anfractibm qiiatuor ad 

 quinqiie, plannlatii, oblique striatis, ultimo ad periplie- 

 riam obtuse carinato; aperturd lunato-circulari ; peritto- 

 mate tenui, paululum rejlexo, niargiitibus appravimalis. 



The pale-banded Helix. Sliell rather largely uinbili- 

 cated, orbicular, somewhat depressed, convex be- 

 neath, white, encircled with three broad chestnut 

 bands ; spire obtuse ; whorls four to five, rather llat- 

 tened, obliquely striated, last whorl obtusely keeled 

 at the periphery ; aperture lunar-circular ; lip thin, 

 a little reflected, margins approximating.

The chestnut bands being very broad and occupying 

 more of the shell than the white ground upon which they 

 are painted, make it appear as if the shell were white- 

 banded upon a chestnut ground.

Salle's Helix. Shell imperforated, conical, rather thin, 

 finely striated and indented, rather shining, ash- 

 yellow, marked with chestnut dot.s and two brown- 

 green bands at the periphery ; spire conical, rather 

 sharp ; whorls five, rather convex, last whorl sculp- 

 tured with impressed concentric lines, slightly angled, 

 but little convex at the base ; aperture rather oblique, 

 lunar-oval, marked interiorly with the bands ; lij) 

 thin, expanded, a little reflected, white, columellar 

 margin callous, broadly dilated, appressed.

The marking and general aspect of this shell reminds 

 one in some measure of the rare and curious //. Maegil- 

 liorayi of New Holland ; from which it is nevertheless far 

 removed and not of the same typical form. 



Species 565. (Mus. Cuming.) 



Helix Bufpomana. Hel. testa perangutti mnbilieatiL,

BuFFOx's Helix. Shell narrowly urabilicatcd, subglo- 

 bosc, distinctly granulated, thin, inflated, roughened 

 with strong oblique folds, chestnut, streaked irre- 

 gularly with white, ornamented with three rather 

 obsolete blackish bands ; spire rather small, conoid, 

 obtuse ; whorls four, convex, the la<'t very large, 

 vesicular ; aperture lunar-oval, livid and slightly iri- 

 descent within ; lip obtuse, with the margins ap- 

 proximating, columellar margin arched, reflected in 

 a vaulted manner over the umbilicus, basal margin 

 thickened, shortly reflected.

This and the following characteristic Mcxicnn species 

 are quite of the European ty|)<-, related in form and 

 general aspect to the coiimiun II. a-ipersa of our gardens.
