Plate XXIII. 
Species 125. (Mus. Taylor.) 
Achatina marmorea. Acliat. testa elongato-turrita, an- 
gustd, subcylindracea, solidiuscula, anfractibus plano- 
convexis, oblique snbrude striatis, columella, tenue trun- 
cate, aperturd pared ; alba, epidermide corned cas-

The marble Achatina. Shell elongately turreted, 
narrow, somewhat cylindrical, rather solid, whorls 
flatly convex, obliquely rather rudely striated, colu- 
mella thinly truncated, aperture small ; white, covered 
with a chestnut horny epidermis. 
Hab. ? 
This species resembles the Bulimus calcar in form. It 
is of more solid growth, and has the columella distinctly 
truncated. 
Species 126. (Mus. Cuming.) 
Achatina mucida. Achat, testa ovatd, tenui, subven- 
tricosa, anfractibus sex, decussatim subtilissime granu- 
loso-striatis, superne marginatis, et obscure crenulatis, 
columella tenumime truncata opaco-albo et pur- 
pureo-fusco strigata et variegatd, epidermide tenui 
induta,. 
The mouldy Achatina. Shell ovate, thin, rather ven- 
tricose, 'whorls six in number, decussately very finely 
granulosely striated, marginated round the upper 
part, and obscurely crenulated, columella very thinly 
truncated ; streaked and variegated with opake- 
white and purple-brown, covered with a thin epi- 
dermis. 
Bulimus mucidus, Gould. 
Hab. Liberia, West Africa.' 
A light, strongly painted shell, of which the colouring 
is seen through in the interior. 
Species 127. (Pig- Guerin.) 
Achatina Saulcydi. Achat, testa oblongo-ovatd, ven- 
tricosa, sinistra, apice subpapillari, anfractibus con- 
vexis , irregulariter rugoso-striatis, ad suturas crenula- 
tis, columella subexcavatd et truncata; molaceo-grised, 
nigricanle-fusco longitudinaliter lineata et strigata, 
aperturce fauce ferrugitieo-fulva. 
Saulcyd’s Achatina. Shell oblong-ovate, ventricose, 
sinistral, somewhat papillary at the apex, whorls 
convex, irregularly roughly striated, crenulated at 
the sutures, columella slightly excavated and trun- 
cated ; violet-grey, longitudinally streaked and linea-

I)e Joannis, Guerin’s Mag. de Zool. 1834, Moll. pi. 50. 
Hab. Prince’s Island, West Africa. 
I have not seen this species, but have ventured to copy 
the excellent figure of it in the work above referred to, on 
account of its characteristic appearance. The papillary 
type of the apex appears also in Bulimus torridus, from 
the neighbouring locality of Liberia. 
Species 128. (Mus. Cuming.) 
Achatina Gouldii. Achat, testa ovato-conica, tenui, 
ventricosa, apice subpapillari, anfractibus plano-con- 
vexis, oblique tenuissime striatis, ad suturas subtiliier 
crenulatis, anfractu ultimo basi leviter angulato ; ful- 
vescente-olivacea, epidermide tenui induta, epidermide 
secundii hydrophones prope apicem radiatd et infra 
angulum anfractiis ultimi unifasciatii. 
Gould’s Achatina. Shell ovately conical, thin, ventri- 
cose, somewhat papillary at the apex, whorls flatly 
convex, obliquely very finely striated, finely crenu- 
lated at the sutures, last whorl slightly angled at the 
base ; fulvous-olive, covered with a thin epidermis, 
rayed at the apex with a second hydrophanous epi- 
dermis, and encircled with a single band of the same 
beneath the angle of the last whorl. 
Bulimus balteatus, Gould. 
Ilab. Liberia, West Africa. 
The name balteatus being already occupied in this 
genus, I have the pleasure of naming the species after the 
accomplished naturalist to whom I am indebted for it, — 
Dr. Gould, of Boston, United States. 
Species 129. (Mus. Taylor.) 
Achatina obeliscus. Achat, testa, elongato-turrita, an- 
fractibus novem ad decern, planis, medio subconcavis, 
transversim obscure et irregulariter liratis, anfractu 
ultimo basi obtuse angulato, columella arcuata et 
March, 1850.
