BULIMUS.— Plate XVIII. 
Of tliis verj' characteristic and pretty species, collected 
in perfection by Mr. Bridges, M. D’Orbigny found but 
two dead specimens in a damp ravine near the banks of 
the Eio San Mateo, Cochabamba, Bolivia, on the North- 
East side of the Eastern Cordilleras. It is chiefly re- 
markable on account of the patulate effused formation of 
the aperture and deep rose-purple stained columella. 
Species 107. (Mus. Cuming.) 
Bulimus tigeis. Bui. tedd cylindraceo-elongatd, ampli- 
ter umhilicatd, anfractibus septem, Icevibus aut subti- 
liter striatk, labro colimellari mblate eapmiso, exterm 
simplici, subeffuso i albidd, pnrpnreo-fiiscescente late

The tiger Bulimus. Shell cyliudrically elongated, largely 
umbUicated, whorls seven in number, smooth or 
finely striated, columeUar lip widely expanded, outer 
lip simple, somewhat effused ; white, broadly streaked 
with purple-brown.

Though approximating very closely to the B. variam, 
there is a sufficient variation in the form of this species to 
render it distinct ; the body-whorl is of greater length 
and the aperture more effused. 
Species 108. (Mus. Cuming.) 
Bulimus onca. Bui. testa elongato-oblongd, tenui, sub- 
pellucidd, anfractibus qu'mque, ultimo maxima, obliquis, 
longitudinaliter striatk, per marginem superiorem levi- 
ter cremdatk, labro vix nfiexo ; violaceo-fulvd, gnttk 
castanek Me illic aspersd, columelld et aperturm fauce 
rosacek. 
The jaguar Bulimus. Shell elongately oblong, thin, 
rather transparent, whorls five in number, the last 
veiy large, oblique, longitudinally striated, slightly 
crenulated along the upper margin, lip scarcely re- 
flected, violaceous fulvous colour, sprinkled here and 
there with large chesnut dots ; columella and interior 
of the aperture pink.

Hab. TutuUma, Bolivia. 
It is entirely owing to the enterprising spirit of M. 
Alcidc D’ Orbigny that we m’e indebted for the knowledge 
of this beautiful species. “ Desiring to find a more im- 
mediate communication,” says that intelligent traveller, 
“between Cochabamba and Moxas, Bolivia, we made a 
proposition to the Government of that Eepublic to make 
the attempt. The President, General Santa Cruz, fiumished 
us with the means to achieve this undertaking. IVe set 
out on foot with a party of Indians to carry provisions, 
and after passing forty days amid the precipices of unin- 
habited momitains on the north-east side of the Eastern 
Cordilleras, and enduring a thousand difficulties and pri- 
vations we accomplished our journey. It was in this 
excursion not far from Tutulima that we observed the 
Bulimus onca at the bottom of almost inaccessible ravines 
in damp woody situations, where it is of rare occurrence 
and difficult to procure, from its habit of burying itself in 
the earth.” 
Species 109. (Mus. Cuming.) 
Buli.mus modestus. Bui. testd pyramidali, turritd, am- 
pliter umbilicatd, anfractibus septem, angustk, rotun- 
datk,fortiter et creberrme concentric^ elevato-striatk, 
labro simplici ; fuscescente, apicem versus albidd, striis 
concenlrick albk. 
The modest Bulimus. Shell pyramidal, turreted, largely 
umbilicated, whorls seven in number, narrow, rounded, 
strongly and very closely concentrically elevately 
striated ; light brown, whitish towards the apex, 
striae whitish.

The whorls of this species have rather a tubercular style 
of growth.
