ACHATINELLA. 



Species 9. (Mus. Cuming.) 



AcHATiNELLA viTTATA. AcJiat. testd dextrorsd, fjlohoso- 

 conicd, suliveutricosd, anfradibus superne sublate mar- 

 ginatis, columella callosd, vix dentatd, labro snhincras- 

 sato ; albd, liiieis vittuque pallide fuscescentilms cin- 

 gulatd, apice nigra. 



The filleted Achatinella. Shell dextral, globosely 

 conical, rather ventricose, whorls rather broadly mar- 

 ginated round the upper part, columella callous, 

 scarcely toothed, lip rather thickened ; white, en- 

 circled with lines and fillets of pale brown, black at 

 the apex. 



Hah. Sandwich Islands. 



This approaches so closely to the sinistral species A. de- 

 cora that it might readily be taken for a dextral variety. 

 The whorls are more rounded and more distinctly margined 

 beneath the sutures. The painting is very similar, but 

 mostly dai'ker next the sutures. 



Species 10. (Fig. a and b. Mus. Cuming.) 



Achatinella lugubeis. Achat, testd subacute conicd, 

 dextrorsd, basin versus ventricosd, anfractibus superne 

 margitiatis, columelld brevi, callosd, dentatd, labro sub- 

 incrassato ; purpureo-nigrd, apice albd, vel albd, nigro 

 aut fusco fasciatd et lineatd. 



The mouening Achatinella. Shell rather sharply 

 conical, dextral, ventricose towards the base, whorls 

 margined round the upper part, columella short, 

 callous, toothed, lip somewhat thickened; purple- 

 black, white at the apex, or white, liueated and 

 banded with brown or black.

 Helix {CocJdogena) luguhiis, Ferussac. 

 Monodonta seminigra, Lamarck. 

 Bulimus seminiger, Menke. 

 Achatinella pica, Swainson. 



Hab. Sandwich Islands. 



Lamarck, mistaking this f«r a marine species, described 

 it as a Monodonta fi'om the shores of Tahiti, where the 

 natives use the shell for making necklaces. It is mainly 

 distinguished by its sharply conical form. 



Species 11. (Mus. Cuming.) 



Achatinella suffusa. Achat, testd oblongo-ovatd, u- 

 nistrorsu, anfractibus convexis, subrude obsolete slria- 

 tis, columelld contorto-plicatd, aperturd simplici ; roseo- 

 albicante, apice fusco-rubente, aperturce fauce carnto- 

 rosed. 



The blushing Achatinella. Shell oblong-ovate, si- 

 nistral, whorls convex, somewhat rudely obsoletely 

 striated, columella with a twisted plait, aperture 

 simple ; pinkish-white, brown-red at the apex, in- 

 terior of the aperture flesh-pink. 



Huh. ? 



A delicately coloured species, partaking very much of 

 the character of Bulimus, the whorls being less smoothly 

 polished than usual and not margined at the sutures. It 

 resembles A. rosea in general aspect, but is a different 

 kiudofsheU. 



Species 13. (Fig. a and h. Mus. Cuming.) 



Achatinella decoea. Achat, testd globoso-conicd, ven- 

 tricosd, sinistrorsd, columelld brevi, lata, plano-callosd, 

 labro subincrassato ; albd, fasciis lineisque castaneis et 

 iiigris varie pictd, columelld lahroque purpurascente 

 tinctis. 



The handsome Ach.vtinella. Shell globosely conical, 

 ventricose, sinistral, columella short, broad, tlatly 

 callous, lip somewhat thickened; white, variously 

 banded with chestnut and black bands and lines, lip 

 and columella stained with light pui-ple. 



Feeussac, Hist. Moll. pi. 155. f. 5 and 7. 

 Achatinella vestita, Mighels. 



Hah. Sandwich Islands. 



Distinguished by its globose ventricose gi-owth, stripetl 

 painting, and light purple colouring of the lip and colu- 

 mella. Ferussae's Fig. 6 represents a distinct species, 

 A. perversa, Swainson. 



Species 13. (Mus. Cuming.) 



Achatinella peoducta. Achat, testd subelongato-co- 

 nicd, dextrorsd, anfractibus convexis, ad suturas leviter 

 marginatis, columelld conspicue calloso-dentatd, aper- 

 turd parvimculd ; olivaceo-viridi, apice, columella, et 

 aperturce fauce albis. 



The puolonged Achatinella. Shell somewhat elou- 

 gately conical, dextral, whorls convex, slightly mar-
