ACHATINELLA.— Plate I. 



flesh-tinged straw-colour, irregularly striated and re- 

 ticulated with blackish-olive flames, interior of the 

 aperture whitish. 



MiGEELS, Pro. Boston Nat. Hist. Soc. 1845, p. 20. 



Hah. Oahu, Sandwich Islands. 



Elegantly streaked and reticidated with dark olive upon 



a warm cream-yellow ground, very promiscuously clouded 



in some specimens, as in J. pic/a and veituda. 



Species 2. (Kg. a and b, Mus. Cuming.) 



AcHATlNELLA PALLIDA. Achat, testd aeuminato-ovatd, 

 soUdlusculd, anfractibus plano-convexis, oblique subrude 

 striatis, superne marginatis, sulco suturk subremoto, 

 columella brevi, late callosd; albd,fusco vel castaneo- 

 nigricaiite 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.

 Eadem var. Acliatinella alba, NuttaU. 



Hab. 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 virgulata. Achat, testd oblonffo-ovatd, 

 veutricosd, aut sinistrorsu aul dextrorsd, anfractibus 

 medio plano-convexii, superne tumidiusculis, lineis spi- 

 ralibus et obliquis undiqne minute decussatis, columella 

 callosd; albidd aut lacted, viltis castaneis, nunc an- 

 guslis, nunc latiusculis, cingulatd, fascia conspicud 

 purpureo-fuscd 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 turn to the 

 genera Partula and Bulimus, belongs unquestionably to the 

 •4C11U3 under consideration, for which it is well characterized 



by its peculiarity of form, structm-e of lip and columella, 

 and design of painting.

Species 6. (Mus. Cuming.) 



Achatinella loeata. Achat, testd ovato-conicd, dex- 

 trorsd, soUdiusculd, anfractibus plano-convexis, lavibus, 

 ad s7ituras marginatis, columella brevi, late appressd, 

 callosd, apertitrd parviusculd ; castaneo-brunned, sutu- 

 ris saturatioribus,fascid unicd albd cingulatd. 



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, encLi'cled with a single white band. 



Helix {Cochlogena) lorata, Ferussac, Hist. Moll. pi. 155. 

 f. 9-11. 



Hab. Sandwich Islands. 



A. mustelina and Butimoides, which Dr. Pfeiffer quotes 



as synonyms of this species, are certainly distinct. 



Species 7. (Mus. Cuming.) 

 Achatinella t.eniolata. Achat, testd ovatd, dextror- 

 sd, subventrieosd, anfractibus convexis, lavibus, colu- 

 mella brevi, late appressd, aperturd parviusculd ; 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. 

 Pfeiffek, Pro. Zool. Soc. 1846. p. 38. 

 Hab. Sandwich Islands. 



About intermediate in its characters between the fore- 

 going species and that which follows. 



Species 8. (Mus. Cuming.) 

 Achatinella Bulimoides. Achat, testd ovatd, dextror- 

 sd, ventricosd, soUdiusculd, anfractibus convexis, lavi- 

 bus, superne marginatis, columella brevi, latissime ap- 

 pressd, callosd; albidd, atifractuum 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. Illus. 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.
