The varicose peculiarity of growth which characterizes 
the A. leucozonias, is developed in a less prominent degree in 
this species, the contrast of painting being reversed. The 
A. leucozonias, is of a dark chestnut-brown marked with 
longitudinal white stripes, in places where the white- 
edged lip has been matured after the manner of a varix. In 
the present species the shell is of a uniform orange-yellow, 
and the periodical maturity of the lip is indicated in its 
course of growth, about four to five times in a whorl, by 
a broad chestnut stripe.

Achatina Peruviana. Achat, testa, fusiformi-oblonga, 
spires suturis peculiariter profunde excavatis, anfrac- 
tibus subplano-couvexis, longitudinaliter creberrime cos- 
tulalis, interstitiis transversim sulcato-striatis, colu- 
mella contortd, et ahnipte truncata, aperturS oblongd; 
alba, jlammis undatis longitudinalibus, lineolisque 
obliquis rufo-fuscis, conspicue pictS. 
The Peruvian Achatina. Shell fusiformly oblong, 
sutures of the spire peculiarly deeply excavated, 
whorls rather flatly convex, longitudinally very closely 
finely ribbed, interstices marked transversely with 
grooved striae, columella twisted and abruptly trun- 
cated, aperture oblong ; white, conspicuously painted 
with red-brown longitudinal flames and oblique lines.

This species belongs apparently to a distinct type, the 
chief peculiarity of which resides in the deeply grooved 
formation of the sutures. It is of rather solid texture 
with somewhat the aspect of a marine shell, finely ribbed 
longitudinally, the ribs turning over the upper edge of the 
whorls into the sutural depression. In painting it is richly 
marked with red brown stripes, crossed obliquely with 
fine lines of the same colour. 
Species 58. (Mus. Cuming.) 
Achatina glabra. Achat, testa acuminato-ovatS, tenui- 
culS, anfractibus septem ad octo, subtilissime longitudi- 
naliter striatis, glabris, nitidis, columella brevi, arcuata 
et contorta ; fulvescente cornea, strigis fuscis remotis, 
suturis anfractmm medio descendentihus, ornatS. 
The smooth Achatina. Shell acuminately ovate, rather 
thin, whorls seven to eight in number, very finely 
longitudinally striated, smooth, shining, columella 
short, arched and twisted ; light fulvous horn-colour, 
ornamented with distant brown streaks, descending 
from the sutures to the middle of the whorls.

This species has a smooth glazed appearance, but not 
arising from the lustre of a homy cuticle, such as that 
which characterizes the A. Lattrei and its congeners.
