Species 28. (Mus. Cuming.) 
Achatina alabaster. Acliat. testa, conico-ovata, crassi-

raliter striatis, suturis subimpressis, columella, vix

The alabaster Achatina. Shell conically ovate,

Helix alabaster, Eang. 
Hah. Prince’s Islands, West Africa. 
The bright chestnut band which encircles this species, is 
constant in all the examples I have seen. 
Pig. 29. (Mus. Cuming.) 
Por this species see Plate X. Sp. 35, A. fasciata, of 
which the shell here figured ( A . crenata, Swainson) is a 
variety. 
Species 30. (Mus. Cuming.) 
Achatina Reeveana. Acliat. testa conico-ovata, tenui- 
culd, anfradibus septem, sub lente minutissime spiraliter 
striatis, oblique subtiliter plicato-striatis, ad suturas 
concentric I crenulatis, columella vix truncata, apertura

Reeve’s Achatina. Shell conically ovate, rather thin, 
whorls seven in number, very minutely spirally stri- 
ated beneath the lens, obliquely finely plicately stri- 
ated, concentrically crenulated at the sutures, colu-

Pfeiffer, Monog. Helic. viv. vol. ii. p. 247. 
Hab. Banks of the river Gaboon, West Africa. 
Distinguished from A. alabaster, to which it is next 
allied, by its larger and lighter structure, sutural crenu- 
lations, and faint colouring of the band. 
Species 31. (Pig. a and b, Mus. Dennison.) 
Achatina fusiformis. Achat, testa fusiformi-oblonga, 
tenui, ventricosd, anfradibus septem , superne obscure 
subangulato-produdis, longitudina liter creberrime sub- 
irregulariter plicato-striatis, striis minutis impressis 
spiraliter indentatis, ad suturas crispato-murginatis, 
columella abrupte truncata, apertura angusld ; strami- 
nea vel fuscescente, eximie miniatd, slrigis angustis hie 
illic saturate pietd, intus pallide rosacea. 
The fusiform Achatina. Shell fiisiformly oblong, 
thin, ventricose, whorls seven in number, obscurely 
slightly angulated round the upper part, longitudi- 
nally very closely but rather irregularly plicately stri- 
ated, spirally indented with minute impressed striae, 
crisply margined at the sutures, columella abruptly 
truncated, aperture narrow ; pale straw-colour, or

Pfeiffer, Pro. Zool. Soc., 1845, p. 75. 
Hab. Mountain of Coban, Vera Cruz, Central America. 
It is scarcely possible to do justice to the delicate co- 
louring and plicated sculpture of this beautiful species, 
the inner edge of the lip of which is stained with a peculiar 
saturnine vermilion, whilst the entire sheR is more or less 
tinged with a warm hue of the same, excepting in the 
variety represented at Pig. 31.4, which is of a bright silky 
straw-colour. 
Species 32. (Mus. Dennison.) 
Achatina Dennisoni. Achat, testa fusiformi-ovata, 
spird subacuminata, anfradibus sex, subrude exiliter 
plicato-striatis, striis subtilibus impressis decussatis, 
apice subpupillari, columella arcuatd et contortd, 
attenuate truncata; fuscescente, fusco apicem versus 
variegata, anfractu ultimo immaculato, fascia pallida 
obscurd dngulato, columella pallide rosacea, supra 
livido-ccerulescente, fusco marginatd. 
Dennison’s Achatina. Shell fusiformly ovate, spire 
rather acuminated, whorls six in number, somewhat 
rudely faintly plicately striated, decussated with fine
