ACHATINELLA.— Plate I. 
flesh-tinged straw-colour, irregularly striated and re- 
ticulated with blackish-olive flames, interior of the 
aperture whitish. 
Mighels, Pro. Boston Nat. Hist. Soc. 1845, p. 20. 
Hah. Oahu, Sandwich Islands. 
Elegantly streaked and reticulated with dark olive upon 
a warm cream-yellow ground, very promiscuously clouded 
in some specimens, as in A.picta and venmta. 
Species 2. (Fig. a and b, Mus. Cuming.) 
Achatinella pallida. Achat, testa acuminato -ovatd, 
solidiuscula, anfractilus plano-convexis, oblique subrude 
striatis, superne marginatis , sulco suturis subremoto, 
columella brevi, late callosa ; albd,fusco vel castaneo- 
nigricante plus minus fasciatd, columella labroque fus- 
cescente-carneis. 
The pale Achatinella. Shell acuminately ovate, 
rather solid, whorls flatly convex, obliquely some- 
what rudely striated, margined round the upper part, 
the groove being rather distant from the sutures, 
columella short, broadly callous ; white, more or less 
banded with brown or chestnut-black, lip and colu- 
mella brownish-flesh.

Eademvar. Achatinella alba , Nuttall. 
Hah. Wahoo, Sandwich Islands ; Nuttall. 
Allied to A. decora , from which it is distinguished by 
its more acuminated and less ventricose form. 
Species 3. (Fig. 3, 4, 5, Mus. Cuming.) 
Achatinella vikgulata. Achat, testa oblongo-ovata, 
ventricosa, aut sinistrorsd aut dextrorsd, anfractibus 
medio plano-convexis, superne tumid iusculis, lineis spi- 
ralibus el obliquis undique minute decussatis, columella 
callosa; albidd aut lactea, vittis castaneis, nunc an- 
gustis, mine latiusculis, cingulald, fascia conspicud 
purpureu-fused prope ad apicem. 
The striped Achatinella. Shell oblong-ovate, ven- 
tricose, either sinistral or dextral, whorls flatly convex 
in the middle, rather swollen round the upper part, 
minutely decussated throughout with spiral and 
oblique lines, columella callous; white or cream- 
colour, encircled with chestnut fillets, promiscuously 
broad or narrow, and a conspicuous dark purple- 
brown band near the apex.

This fine species, which has been referred in ton to the 
genera Partula and Bulimus, belongs unquestionably to the 
genus under consideration, for which it is well characterized I 
by its peculiarity of form, structure of lip and columella, 
and design of painting.

Species 6. (Mus. Cuming.) 
Achatinella lorata. Achat, testa ovato-conicd, dex- 
trorsd, solidiuscula, anfractibus plano-convexis, Icevibus, 
ad suturas marginatis, columella brevi, late appressa, 
callosa, apertura parviuscula ; castaneo-brunned, sutu- 
ris saturalioribus, fascia unica alba cingulata. 
The belted Achatinella. Shell ovately conical, 
dextral, rather solid, whorls flatly convex, smooth, 
margined at the sutures, columella short, broadly 
appressed, callous, aperture rather small ; chestnut- 
brown, encircled with a single white band.

Had). Sandwich Islands. 
A. mustelina and Bulimoides, which Dr. Pfeiffer quotes 
as synonyms of this species, are certainly distinct. 
Species 7. (Mus. Cuming.) 
Achatinella t.eniolata. Achat, testa ovatd, dextror- 
sd, subventricosa, anfractibus convexis, Icevibus, colu- 
mella brevi, late appressa, aperturd parviuscula ; al- 
bidd, fusco varie fasciatd. 
The filleted Achatinella. Shell ovate, dextral, 
rather ventricose, whorls convex, smooth, columella 
short, broadly appressed, aperture rather small ; 
whitish, variously banded with brown. 
Pfeiffer, Pro. Zool. Soc. 1846. p. 38. 
Hah. Sandwich Islands. 
About intermediate in its characters between the fore- 
going species and that which follows. 
Species 8. (Mus. Cuming.) 
Achatinella Bdlimoides. Achat, testa ovatd, dextror- 
sd, ventricosa, solidiuscidd, anfractibus convexis, Icevi- 
bus, superne marginatis, columella brevi, lalissime ap- 
pressa, callosa ; albidd, anfractuum parte inferiori cas- 
taneo-brunned. 
The Bdlimus-like Achatinella. Shell ovate, dextral, 
ventricose, rather solid, whorls convex, smooth, 
margined round the upper part, columella short, 
very broadly appressed, callous ; whitish, lower part 
of the whorls chestnut-brown. 
Swainson, Zool. Ulus. 2nd Series, vol. ii. pi. 108. f. 1. 
Hab. Sandwich Islands. 
Larger and more ventricose than either of the two pre- 
ceding allied species, it differs more especially from the 
latter, which it most resembles in form, in having the 
whorls margined next the sutures.
