Plate XVIII. 



Species 82. (Mus. Ciiniing.) 

 Ampullakia prdnulum. Amp. testa globosd, subdiscoi- 

 ded, profunde umbilicatd, spird breviusculd, acuminata, 

 anfraclibus sitperue impresso-planis, deinde convexis ; 

 livido-olivaced, lined fmcesceute obscure cingtdatd ;

 The little plum Ampullakia. Shell globose, sub- 

 discoid, deeply umbilicated, spii'e rather short, acu- 

 minated, whorls impressly flattened round the upper 

 part, then convex ; livid olive, obscurely encircled 

 with a faint brown line ; aperture ovate, coluraellar 

 lip rather effused, interior pale orange. 

 Ilab. Xew Granada. 



Of the same typical outline as A. luteostoma, but less 

 effused, and having a narrower umbilicus, with little ex- 

 ternal painting except a fi\int line or two. 



Species 83. (Fig. a, b, Mus. Cuming.) 



.-Vmi'ULLaria Cubensis. Amp. testa subglobosd, suhpro- 

 funde umbilicatd, spird exsertd, anfractibus rotundatis, 

 lavibus; Uvido-cinered, fasciis angustis rufts regula- 

 riter citigulatd ; aperturd ovatd, subexpamd. 



The Cuba Ampullakia. Shell subglobose, rather deeply 

 umbilicated, spire esserted, whorls rounded, smooth ; 

 livid ash, regularly encircled with narrow red bands ; 

 aperture ovate, rather expanded. 



Hab. Cuba. 



The regularity of the red banils with which this species 



is striped, is rather a characteristic feature. 



Species 84. (Mus. Cuming.) 



Ampullakia luteostoma. Amp. testa orbiculato-veti- 

 tricosd, subdiscoided, perampliter umbilicatd, spird 

 breviusciild, acuminata, anfractibus superne subimpres- 

 sis, deiiide rotundatis ; flavescente-fuscd, lineis brunneis 

 duabiK vel tribus dislautibus cingulatd ; aperturd ovatd, 

 labro subeffiiso,faHce aurantid. 



The yellow-mouth Ampullakia. Shell orbicularly 

 ventricose, somewhat discoid, very largely umbili- 

 cated, spire rather short, acuminated, whorls rather 



impressed round the upper part, then rounded ; yel- 

 lowish-brown, encircled with tvvo or three distant 

 brown lines ; aperture ovate, lip somewhat effused, 

 interior orange.

Hab. Venezuela. 



ReadOy distinguished from the preceding species by its 



larger size and rougher epidermis-clad texture, the colu- 



mellar lip being less broadly reflected back. 



Species 85. (Fig. «, b, Mus. Cuming.) 

 Ampullakia glauca. Amp. testa orbiculato-veutricosd, 

 subdiscoided, ampliter umbilicatd, spird brevi, anfracti- 

 bus superne planulatis, deinde plano-eonvexis ; fusces- 

 cente, fasciis lineisqiie glauco-eastaneis dense cingulatd; 

 aperturd ovald, ampld, labro columellari late effuso, 

 fauce aurantid. 

 The GLAUCOUS Ampullakia. Shell orbicularly ventricose, 

 somewhat fiiscoid, largely umbilicated, spire short, 

 whorls flattened round the upper part, then flatly 

 convex ; pale brown, closely encircled with glaucous- 

 chestnut lines and bands ; aperture ovate, large, co- 

 lumellar lip broadly eft'used, interior orange.

Uab. ? 



A very characteristic species, distinguished by its shin- 

 ing porcelain-like aspect and broadly effused reflection of 

 the columellar lip, which, with the interior, is enamelled 

 orange, the external surface of the shell being closely lined 

 and banded with glaucous-chestnut.
