The paper Achatina. Shell oblong-ovate, thin, whorls

little truncated ; light brown, clouded with darker 
brown, columella sometimes pinkish.

Hab. Banks of the river Nun, Africa. 
A light semi-transparent shell, of which the interior is 
slightly iridescent. 
Species 7. (Mus. Cuming.) 
Achatina balteata. Achat, testa acuminato-oblongd, 
subfusiformi, crassiuscida, anfractibus oclo ad novem, 
subplicato-striatis, undique creherrime minute granula- 
tis, columelld peculiariter arcuala, el contorts, abrupte 
truncatd ; Jlavescente, / asciis castaneis longitudinalibus 
apicem versus tinctd, fascia spirali interrupts, subin- 
distinctd, medio cingnlalis, columelld et apertures fauce 
ccerulescente-albd. 
The belted Achatina. Shell acuminately oblong, 
somewhat fusiform, rather thick, whorls eight to nine 
in number, slightly plicately striated, very closely 
minutely granulated, columella peculiarly arched and 
twisted, abruptly truncated ; yellowish, stained 
towards the apex with chesnut longitudinal bands, 
and encircled round the middle with a rather indis- 
tinct interrupted spiral band, columella and interior 
of the aperture bluish-white. 
Hab. Banks of the river Gambia, Africa. 
Very beautifully minutely granulated throughout, and 
characterized by a faint spiral band, in a manner which 
obtains some specific importance on account of its singu- 
larity. 
Species 8. (Mus. Cuming.) 
Achatina fulica. Achat, testa fitsiformi-oblongS, sub- 
ventricosa, nunc tenui, nunc crassiuscida, anfractibus 
octo, Icevibus, apicem versus obscure granulato-striatis, 
ad suturas vix crenulatis, columelld subcontortd, an- 
guste truncatd ; lutescente-albd, fusco profuse latistri- 
gatd et nebulata, columelld et aperturccfav.ee albis. 
The smoked Achatina. Shell fusiformly oblong, 
rather ventricose, sometimes thin, sometimes thick, 
whorls eight in number, smooth, obscurely granosely 
striated towards the apex, but slightly crenulated at 
the sutures, columella rather twisted, narrowly trun- 
cated; yellowish-white, profusely broadly streaked 
and clouded with brown, columella and interior of 
the aperture bluish-white.

Achatina Couroupa, Lesson. 
Hab. Mauritius. 
An extremely variable species ; in addition to the typical 
specimen here figured it has been necessary to represent 
(PI. III.) a variety of smaller size which is of frequent 
occurrence, and one (PI. XI.) of singular umbilicated 
growth. The variety Fig. 8, b. is of rather light structure, 
and extremely constant in this peculiarity. MM. Quoy 
and Gaimard distinguished it as a separate species with 
the name B. Mauritiana, but it is found associated with 
the larger kind and differs immaterially in form or sculpture. 
This variety is, however, a very characteristic one, and is 
found abundantly in some parts of Mauritius. When the 
Samarang touched at that island on its return to England, 
Sir David Barclay, an eminent collector residing at Port 
Louis, presented Sir Edward Belcher with some thirty or 
forty of them alive from his garden, scarcely differing from 
one another in size or painting. 
In the variety figured at PL XI, a very remarkable one, 
the shell is pressed down, as it were, and the whorls are 
turned in a manner to form a large umbilicus. Specimens 
of this variety are not very uncommon, and may be seen in 
different stages of growth. 
Species 9. (Mus. Cuming.) 
Achatina reticulata. Achat, testa elongato-ovata, 
subfusiformi, erased, anfractibus novem, plicato-rugosis, 
et striatis, ad suturas concentrice crenatis, columelld 
February, 1849.
