ACHATINA.— Plate XV. 
Species 64. (Mus. Cuming.) 
Achatina Gkxfexthsxi. Achat, testa subfusiformi, spira 
acuminatd, anfractibus novem, creberrime et subtilissime 
costulato-striatis , ultimo medio impresso, basi expanse, 
columella, contortd, attenuate truncata; pellucido-albd, 
strigis castaneis sparsis oblique pietd. 
Griffith’s Achatina. Shell somewhat fusiform, spire 
acuminated, whorls nine in number, very closely and 
finely sculptured with rib-like striae, last whorl im- 
pressed in the middle and expanded at the base, colu- 
mella twisted, attenuately truncated; transparent- 
white, obliquely painted with scattered chestnut 
streaks. 
Adams, Pro. Boston Nat. Hist. Soc., 1845, p. 14. 
Sab. Jamaica. 
The compressed growth of the last whorl has very much 
the appearance of an accidental distortion. 
Species 65. (Mus. Cuming.) 
Achatina Bangiana. Achat, testa elongato-turrita, 
crassd, solidd, anfractibus undecim, plano-convexis, sub- 
tilissime arcuatim striatis, lineis impressis spiralibus 
subdistantibus obscure notatis, columella simplici, callo- 
sa, vix truncata, aperturd pared ; albido-stramined. 
Bang’s Achatina. Shell elongately turreted, thick, 
solid, whorls eleven in number, flatly convex, very 
finely arcuately striated, obscurely marked with 
rather distant impressed spiral lines, columella simple, 
callous, scarcely truncated, aperture small ; whitish 
straw-colour. 
Pfeiffer, Pro. Zool. Soc., 1846, p. 115. 
Hob. Bepublic of Mexico ; Linden. 
A shell of peculiarly solid growth verging on Bulimus, 
allied to the elongately turreted group of that genus of 
which B. calcareus is the type. 
Species 66. (Mus. Cuming.) 
Achatina Tortillana. Achat, testa subfusiformi- 
oblongd, subventricosd, arfractibus septem, subtilissime 
et creberrime costulato-striatis, columella contortd et 
attenuate truncata ; lutescente-corned,pellucidd, quasi 
vitred. 
The Tortilla Achatina. Shell somewhat fusiformly 
oblong, rather ventricose, whorls seven in number, 
,very finely and closely rib-like striated, columella 
twisted and attenuately truncated ; yellowish horny, 
transparent, as though glassy. 
Pfeiffer, Pro. Zool. Soc., 1846, p. 32. 
Eab. Tortilla, Central America. 
The opake blotches and streaks described by Dr. Pfeiffer, 
appear to be merely accidental in the individual specimen. 
Species 67. (Mus. Cuming.) 
Achatina assimilis. Achat, testa oblonga, apice sub- 
obtusd, anfractibus sex, Icevibus, politis, e suturis sub- 
tilissime impresso-striatis, superne tenuimarginatis, 
columella breviter reflexd, aperturd oblonga ; vivide 
pellucido-cornea. 
The allied achatina. Shell oblong, rather obtuse at 
the apex, whorls six in number, smooth, polished, 
very finely impressly striated at the sutures, thinly 
margined round the upper part, columella shortly 
reflected, aperture oblong ; bright transparent horny. 
Eab ? 
This approaches very closely to the A. obtusa, Sp. 62, 
but is of more transparent texture, whilst the columella is 
less abruptly truncated. The shell is composed of a 
whorl less in number, and the spire is shorter. 
Species 68. (Mus. Cuming.) 
Achatina Hugeli. Achat, testa pyramidali-oblongd, an- 
fractibus decern, rotundatis, superne subtilissime arcuatim 
striatis, ad suturas minute marginatis, columella valde 
arcuatd et contortd, aperturd pared; pellucido-albi- 
cante, liyalind, epidermide tenui corned lulescente. 
Hegel’s Achatina. Shell pyramidally oblong, whorls 
ten in number, jounded, very finely arcuately stri- 
ated at the upper part, minutely margined at the 
sutures, columella much arched and twisted, aperture 
small; transparent whitish, hyaline, with a thin 
yellowish horny epidermis. 
Pfeiffer, Symboke, vol. ii. f. 58. 
Eab. P 
A neat hyaline species of pyramidal growth, marked with 
delicate covered stria! round the upper part of the whorls, 
which become fainter as the shell approaches maturity.
