cose, rather thin, whorls five in number, very closely 
minutely granulated, columella twisted ; brown,

Rob. ? 
This is apparently a shell of immature growth, but so 
peculiar in its colour and marking, that I venture to 
describe it as new. Of a warm brown silken hue, painted 
with fine sharply zigzag streaks somewhat broken, much 
more delicate and numerous towards the apex. 
Species 39. (Mus. Cuming.) 
Aciiatina flammigeba. Achat, testa subpyramidali- 
ovatd, anfractibus septem ad octo, oblique obscurb pli- 
cato-rugosis, columella recta, vix truncatd, aperturd 
parmuscula ; lutescente, flamniis subtilibm fre/quentibus 
ustulato-fuscis oblique pietd, basi nigricante-Castaned. 
The flamed Achatina. Shell somewhat pyramidally 
ovate, whorls seven to eight in number, obliquely 
obscurely plicately wrinkled, columella straight, 
scarcely truncated, aperture rather small ; yellowish, 
obliquely painted with frequent fine burnt-brown 
flames, base blackish chestnut.

Cochlitoma flammigera, Ferussac. 
Bulimus Richii, Lamarck. 
Achatina Richii, mihi, in Conch. Syst. 
Hab. Peru. 
The columella being very slightly truncated in this 
species, partakes very much of the character of Bulimus. 
Species 40. (Mus. Cuming.) 
Aciiatina ustulata. Achat, testa cylindraceo-oblonga, 
spira exsertd, anfractibus septem, granato-striatis, striis 
in anfractu ultimo evanidis, columella subcontortd, 
abrupte truncatd, aperturd pared ; nigricante-Castaned, 
strigis lutescentibus longiludinaliter f ulgur atis, apertures 
fauce ceerulescente. 
The bubnt Achatina. Shell cylindrieally oblong, spire 
stretched out, whorls seven in number, granosely 
striated, striae fading away in the last whorl, colu- 
mella slightly twisted, abruptly truncated, aperture 
small ; blackish chestnut, marked with longitudinal 
yellowish zigzag streaks, interior of the aperture 
bluish.

Well characterized by its cylindrical^ drawn out form 
and style of painting. 
Species 41. (Mus. Itolf'c.) 
Aciiatina lactea. Achat, testa ovatd, crassiusculd, an- 
fractibus tumidiusculis, undique plicato-striatis et gra- 
natis, columella arcuata, callosa, attenuate truncatd ;

thick, whorls somewhat swollen, plicately striated and

Hab. Zanzibar. 
An extremely characteristic species of a pure uniform 
cream colour without any indication of pattern. 
The specimen originally described, and from which the 
accompanying figure from the Conehologia Systematica 
was engraved, is in the possession of the Rev. S. C. E. 
Neville Rolfe of Heacham Hall. Mr. Cuming has since 
obtained similar specimens from Zanzibar. 
March, 1849.
