HELIX.— Plate LXVII. 



Species 350. (Mus. Cuming.) 



Helix incoxspicua. Ilel. iedd umbilicatd, suhdkcoided, 

 pallide corned, (enuissime striatd ; spird vix elevaid, 

 apice oblusd ; mifraclibus quatuor ad (juinque, con- 

 vexis, ultimo superne subangulalo ; aperturd angtutd, 

 Ittttari, labro simplici. 



The inconspicuous Helix. Shell umbilicated, sub- 

 discoid, pale horny, veiy finely striated ; spire but 

 little raised, obtuse at the apex ; whorls four to five, 

 convex, the last slightly angled at the upper part ; 

 aperture narrow, lunar, lip simple.

Hab. Jamaica. 



Chiefly distinguished by the angular structure of the 

 upper part of the whorls, which gives a broad flattened 

 appearance to the spire. 



Species 351. (Mus. Cuming.) 



Helix simulans. Jlel. testd vix timhiUcutd, ova(d,fulvo- 

 corned, nitente ; spird ekvaliusculd ; anfractibus qua- 

 tuor, plano-convexis, lineis obliquis incremenii subti- 

 limme sculptis ; aperturd lunari-rotundatd, labro sim- 

 plici. 



The resembling Helix. Shell scarcely umbilicated, 

 ovate, fulvous-horny, shining ; spire rather elevated ; 

 whorls four, flatly convex, very finely sculptured with 



oblique lines of growth ; aperture lunar-rounded, lip 



simple.

Professor Adams seems rightly to have distinguished 

 this species from Jl.fiisca of Miiller, more especially as 

 there is so little in common between the faunas of Europe 

 and the West Indies. 



Species 352. (Mus. Adams.) 



Helix saxicola. Hel. testd subprojundi umbilicald, or- 

 biculato-convexd, teniii, nilidu, minutissime striatd, 

 coriieo-fuscd ; anfractibus quatuor ad quiiique, contex- 

 iuscuUs, seyisini accresceutibiis ; aperturd subcirculari ; 

 peristomate simplici, acuto, marginibus conniventibut. 



The stone-inhabiting Helix. Shell somewhat deeply 

 umbilicated, orbicularly convex, thin, shining, very 

 minutely striated, horny-brown ; whorls four to five, 

 rather convex, increasing gradually ; aperture nearly 

 circular ; lip simple, sharp, with the margins approxi- 

 mating.

Eesembling the preceding species, except that the 

 whorls are more depressly and widely convoluted, giving 

 a larger umbilicus.
