BULIMUS. 
Plate XXI. 
Species 138. (Mus. Cuming.) 
Bulimcs decolobatos. Bui. testa, ohhngo-matd, an- 
fractibus quinque, medio svhangulato-ventrkosis, infra 
suturas peculiariter hngitudiualiter crenidath, labro 
simplici ; albidd, fuscescente Me illic ietmiter strigatd, 
parte circa columellam castaneo-fused. 
The discoloured Bolimds. Shell oblong-ovate, whorls 
five in number, somewhat angularly ventricose in the 
middle, peculiarly longitudinally crcnulatcd beneath 
the sutures, lip simple ; whitish, finely streaked here 
and there with light brown, chesnut brown round 
the columella. 
Sowerby, Pro. Zool. Soc., 1333, p. 73. 
Hab. Vicinity of Lima, Peru (found buried in the earth 
under bushes on the hills) ; Cuming. 
The first two whorls of this shell are characterized by a 
very minute, shagreen appearance, discernible only with 
the lens, but it may be doubted whether it is of any 
specific value. 
Species 139. (Pig. a and b. Mus. Cuming.) 
Bulimus Scalabiformis. Bui. testa pyramidali-oblongd, 
ampliter unibilicatd, anfractibus sex, rokmdatis, cre- 
berrivie concentric^ tenukostatis, aperturd pared, labro 
simplici j fuscescente, costis alhidis. . 
The Scalabia-shafed Bulimus. Shell pyramidally 
oblong, largely umbibcated, whorls six in number, 
round, very closely concentrically finely ribbed, aper- 
ture small, lip simple ; light brown, ribs whitish. 
Brodebip, Pro. Zool. Soc., 1833, p. 31. 
Ancon, Peru; Cuming. Vicinity of Lima; D’Orbigny. 
An extremely interesting species of which two speci- 
mens are represented, illustrative of its variation of growth. 
M. D’Orbigny relates having found it in great abundance 
among the ruins of a temple erected by the ancient Incas 
in honour of their invisible god, Pachacamac. 
Species 130. (Mus. Cuming.) 
Bulimus ustulatus. Bui. testa oblongo-ovatd,subamplite7' 
umbilkatd, anfractibus sex, subrotundis, concentrice 
rude striatis, labro simplici ; nstulato-fuscd, spiraliter 
vark lineatd. 
The scorched Bulimus. Shell oblong-ovate, rather 
largely umbdicated, whorls six in number, somewhat 
rounded, concentrically rudely striated, lip simple ; 
burnt brown, variously spirally lineated. 
Sowerby, Pro. Zool. Soc., 1833, p. 73. 
Hab. Charles’ Island, GaUapagos (under detached pieces 
of lava) ; Cuming. 
The lineated pattern of this species is somewhat variable, 
but it is always characterized by the same scorched brown 
hue. 
Species 131. (Mus. Cuming.) 
Bulimus mebidionalis. Bid. testa cglindraceo-ovald, 
tenuiculd, vix umbilkatd, anfractibus sex, pecidiariter 
scabroso-incisis, prope suturas irregulariter lineari- 
sukatis, columella angidariter contortd, aperturd ob- 
longd, leviter compressd ; sordide alba, apertura fauce 
intense purpureo-rufd. 
The southern Bulimus. Shell cylindricaUy ovate, rather 
thin, scarcely umbdicated, whorls six in number, 
pecubarly scabrously engraved, irregularly linearly 
grooved near the sutures ; columella angidarly twisted, 
aperture oblong, slightly compressed; dead white, 
interior of the apertiue rich purple red. 
Hab. Chdi; Bridges. 
A very singular species, which appears to have escaped 
the vigilant search of both Cuming and D’Orbigny. It 
is very unlike any other Chilian species. Of a cylindri- 
caUy oblong foi-m, its dead white surface is curiously en- 
graved with obtuse or obsolete scales, and the interior is 
stained with a deep purple-red colour. The columella has 
a curious angidar prominence, which does not, however, 
form an inner fold as in the Auricula-like species. 
Species 133. (Mus. Cuming.) 
Bulimus bilineatus. Bui. testa pyramidali-oblongd, 
umbilkatd, anfractibus septem, convexis, Icevibus, aper- 
turd pared, labro simplici; fuseescente-albd, Uneis 
duahus rufescentibus cingulatd. 
The two-lined Bulimus. SheU pyramidaUy oblong, 
umbdicated, whorls seven in number, convex, smooth, 
aperture smaU, lip simple ; brownish-white, encircled 
by two reddish lines.
