Species 22. (Pig. a and b, Mus. Cuming.) 
Achatina hueeea. Acliat. testa pyramidali-conica, apice 
tumida, Iasi subplanatd et angulatd, anfractibus sex, 
IcEvibus, politis, ad suturas minutissime marginatis, co- 
lumella vix truncatd ; pallide luted, maculis cmruleo- 
viridibus oblongo-quadratis undatis pulclierrime tessel- 
latd, interdum vivide luted, immaculatd, apice roseo- 
incarnatd. 
The poecelain Achatina. Shell pyramidally conical, 
swollen at the apex, somewhat flattened and angular 
at the base, whorls six in number, smooth, polished, 
very minutely marginated at the sutures, columella 
slightly truncated; pale yellow, very prettily tessellated 
with waved oblong-square blue-green spots, some- 
times bright yellow, unspotted, tinged with flesh-pink 
at the apex. 
Bab. ? 
A pretty species, clearly distinct from the A.fasciata. 
Species 23. (Mus. Cuming.) 
Achatina zebea. Acliat. testa subelongato-oblongd, cras- 
siusculd, anfractibus octo, granoso-striatis, grants in 
anfractu ultimo evanidis, columella subcontorta ; intense 
castanea, strigis angustis albis crebre fulguratd, aper- 
tures fauce ceerulescente-albd. 
The zebea Achatina. "Shell elongately oblong, rather 
thick, whorls eight in number, granosely striated, 
grains disappearing on the last whorl, columella 
slightly twisted; very dark cliesnut, marked with 
close narrow zigzag white streaks, interior of the 
aperture bluish-white.

Bab. Caffraria, South Africa. 
It is curious to observe in this species, that the longitu- 
dinal streaks become gradually narrower and more frequent 
as the shell increases in growth. For a species commonly- 
placed with this in collections, in which the stripes are 
broader and much fewer in number, and which differs 
manifestly in form, see the preceding Plate, Sp. 18. 
Species 24. (Mus. Cuming.) 
Achatina caeinata. Achat, testa pyramidali-conica, 
basi plano-angulata, anfractibus sex ad septem, plano- 
convexis, sub lente minutissime decussatis, suturis sub- 
excavatis, columella vix truncatd ; pellucido-alba, fascia 
opaco-albd ad suturas et, in anfractu ultimo, ad angulum. 
The heeled Achatina. Shell pyramidally conical, 
flatly angled at the base, whorls six to seven in 
number, flatly convex, under the lens very minutely 
decussated, sutures somewhat hollowed, columella 
scarcely truncated; transparent white, encircled at 
the sutures with a band of opake white, continued 
round the angle of the last whorl.

Bab. ? 
An interesting species, distinguished by its angular 
structure and delicate milk-white sutural band. 
February, 1849.
