ACH ATINELLA. 
Plate II. 
Species 9. (Mus. Cuming.) 
Achatinella vittata. Acliat. testa dextrorsa , globoso- 
conicd, subventricosd, anfractibus superlie sublate mar- 
ginalia, columella callosa, vix dentatd, labro subincras- 
sato ; alba, lineis vittisque pallide fuscescentibus 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. 
Hab. 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 darker next the sutures. 
Species 10. (Pig. a and b. Mus. Cuming.) 
Achatinella lugubeis. Achat, testa subacute conicd, 
dextrorsa, basin versus ventricosa, anfractibus superne 
marginatis, columella brevi, callosa, dentatd, labro sub- 
incrassato ; purpureo-nigrd, apice albd, vel alba, nigro 
aut fusco fasciald et lineata. 
The mourning Achatinella. Shell rather sharply 
conical, dextral, ventricose towards the ba’se, whorls 
margined round the upper part, columella short, 
callous, toothed, lip somewhat thickened; purple- 
black, white at the apex, or white, lineated and 
banded with brown or black.

pi. 209. f. 2059, 2060. 
Helix ( Cochlogem ) lugubris, Perussac. 
Monodonta seminigra, Lamarck. 
Bulimus seminii, y, Menke. 
Achatinella pica, Swainson. 
Hab. Sandwich Islands. 
Lamarck, mistaking this for a marine species, described 
it as a Monodonta from 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 stjffdsa. Achat, testa oblongo-ovatd, si- 
nistrorsd, anfractibus convexis, subrude obsolete stria- 
tis, columella contorto-plicata, aperture, simplici; roseo- 
albicante, apice fusco-rubente, apertures fauce cameo- 
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. 
Hab. ? 
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 
kind of shell. 
Species 12. (Pig. a and b. Mus. Cuming.) 
Achatinella decoea. Achat, testa glohoso-conicd, ven- 
tricosd, sinistrorsd . , columella brevi, lata, piano-callosa, 
labro subincrassato ; albd, f asciis lineisgue castaneis el 
nigris varie pietd, columella labroque purpurascenle 
tinctis. 
The handsome Achatinella. Shell globosely conical, 
ventricose, sinistral, columella short, broad, flatly 
callous, lip somewhat thickened; white, variously 
banded with chestnut and black bands and lines, lip 
and columella stained with light purple. 
Peeussac, Hist. Moll. pi. 155. f. 5 and 7. 
Achatinella vestita, Mighels. 
Hab. Sandwich Islands. 
Distinguished by its globose ventricose growth, striped 
painting, and light purple colouring of the lip and colu- 
mella. Perussac’ s Pig. 6 represents a distinct species, 
A. perversa, Swainson. 
Species 13. (Mus. Cuming.) 
Achatinella peoducta. Achat, testa subelongato-co- 
nied, dextrorsa, anfractibus convexis, ad suturas leviter 
marginatis, columella conspicue calloso-dentatd, aper- 
turd parviusculd ; olivaceo-viridi, apice, columella, et 
apertures fauce albis. 
The peolonged Achatinella. Shell somewhat elon- 
gately conical, dextral, whorls convex, slightly mar- 
April, 1850.
