42 HELICIDA. 
Eremina, Pfr., 1855. (Erinna, Moérch, 1865. Eremophila, 
Kobelt, 1871.) Shell depressed globose, sharply striate, creta- 
ceous, base convex. H. desertorum, Fursk. (xev, 59). 5 sp. 
Egypt. 
Tachea, Leach, 1820. (Archelix, Albers,1850. Cepza, Held, 
1837.) Shell imperforate, or umbilicus covered, turbinately 
globose or depressed; last whorl ventricose, deflected at the 
aperture, other whorls somewhat flattened; aperture obliquely 
rounded; peristome reflected; columellar lip narrow, callous, 
gibbous. ll sp. Europe. H. hortensis, Mull. xev, 61), the 
common garden-snail of Europe, is a representative of this group, 
which includes several species. Introduced into the United 
States, it has become acclimated at several localities. 
Rhagada, Albers, 1860. Shell imperforate, subglobose, striate, 
white, fasciate; whorls regularly increasing, slightly convex, 
the last slightly deflected .in front, base convex; aperture 
obliquely lunar; peristome a little expanded, labiate within. ZH. 
Reinga, Gray (xcv, 60). 6 sp. Australia, New Zealand. 
Pomatia, Beck, 1837. (Ccenatoria, Held, 1837.) Shell globose, 
striate, corneo-caleareous, umbilicus partly covered or imper- 
_forate, usually fasciate; whorls 4-6, convex, the last large, 
ventricose, descending in front; aperture lunately orbicular , 
peristome patulous or straight, callous within, columellar margin 
retlected, usually callous. H. pomatia, Linn. (xevi, 76). 45 sp. 
Mostly Europe, Western Asiaand Northern Africa. Throughout 
Southern Europe the breeding of the edible snail (Helix pomatia) 
is very extensively carried on; it has been stated that Marseilles 
ships annually to Paris and London from 500 to 750 tons of this 
mollusk, and Genoa exports an equal quantity. Foreign resi- 
dents in the United States are believed to be large consumers of 
this delicacy. In the markets of the warmer regions of Hurope 
basketfuls of live snails are among the most familiar articles of 
food exposed for sale. 
Cantareus, Risso, 1826. (Lucena, Hartmann, 1821. Tapada, 
Gray, 1840.) Paucispiral, thin, diaphanous, imperforate, peris- 
tome simple, sharp. H. aspersa, Born. 
Cryptomphalus, Moquin-Tandon, 1855. Rather thin, imper- 
forate; with thin, twisted columella; epiphragm plane, mem- 
branaceous. H. aspersa, Muller (i, 17, scalariform). 13 sp. 
Europe, Australia, Mexico. 
Macularia, Albers, 1850. (Otala, Moquin-Tandon, 1855.) Im- 
perforate, turbinate or globosely depressed ; whorls four or five, 
convex, the last deflected near the aperture ; aperture obliquely 
rounded; peristome sharp, lipped; columellar lip dilated, ap- 
pressed, covering the umbilicus. //. Niciensis, Fer. (xcv, 62). 
44 sp. Mediterranean region.
