BULIMUS.— Plate I. 
recently discovered by Mr. Adams, of H.M.S. Samarang, 
by the accidental falling of a huge tree, in a woody islet 
situated between Banguey and Balambangan, but they 
are of rare occurrence in that locality. In Europe, where 
nature is exposed to the vicissitudes of a colder climate, 
the Bulimi are mostly small and exhibit no brOliancy of 
colour. So also, in the extensive region of North America, 
where no more than a few insignificant species are known 
to exist. It is in the richly fertile and woody district of 
Columbia, that the genus Bulimus is represented with a 
magnificence little inferior to that of the Philippine 
Islands; here they are large enough and sufficiently 
abundant to be roasted and eaten by the aborigines as a 
frequent article of food. Several fine species, entirely 
new to science, have been collected in Venezuela and 
New Granada by Mr. Linden, an assiduous Botanical 
Traveller, only within the last twelvemonth, at an altitude 
of from 5000 to 8000 feet, and many more, no doubt, 
dwell in undisturbed solitude in the vast interior of this 
immense continent. It is extremely probable that a large 
portion of South America yet remains to be explored by 
the adventurous naturalist, where there is no doubt a fine 
expanse of forest country, grand in extent, rich in foliage, 
and possessing all the elements favourable to the growth 
and beauty of arboreal moUusks. 
Species 1. (Mus. Cuming.) 
Bulimus macrostoma. BuL testa ovdli, ventricosd, 
spird aubabbreciatd, anfraciibiis senis, convexo-tumidis, 
concentrice striatis, eolumelld basi snbeontortd; pur- 
ptireo-fuscd, epidermide kydrophand, in anfractu ultimo 
unizonatd, indtitd; aperturd cmruleacente-albd, labro 
rejlexo. 
The wide-mouth Bulimus. Shell oval, ventricose, 
spire slightly abbreviated, whorls six in number, 
convexly tumid, concentrically striated, columella 
slightly twisted at the base ; purple-brown, covered 
with a hydrophanous epidermis, marked with a single 
zone on the last whorl; aperture blueish white, hp 
reflected.

Philippines (on leaves of trees) ; Cuming. 
This species approaches the B. rufogaster, it partakes 
of the same shades of colour, and the epidermis is charac- 
terised by a similar zone round the last whorl ; it does not 
however exhibit the vacant patches beneath the sutures. 
The columella of B. macrostoma is slightly twisted, and 
the general form of the shell is eminently distinguished 
by its swollen egg-shaped growth. 
Species 2. (Eig. a and b. Mus. C umin g.) 
Bulimus pythogastek. Bui. testd subpyramidali-ovatd, 
anfractibus senis, plano-convexis, ultimo ventricoso, 
eolumelld recta ; purpureo-nigricante, epidermide in- 
terduni svmplwi, interdum longitudinaliier strigatd, 
aperturd caerulescente-alld, eolumelld rosaceo-purpu- 
rascente. 
The oriental Bulimus. Shell somewhat pyramidally 
ovate, whorls six in number, flatly convex, the last 
ventricose, columella straight ; purple-black, epider- 
mis sometimes simple, sometimes arranged in longi- 
tudinal streaks, aperture blueish white, columella 
pinkish purple.

of Luzon, Phihpjiines (on leaves of trees) ; Cuming. 
The examples oiB.pytJiogaster selected for representation 
vary so materially in form, as well as in the arrangement of 
the epidermis, that one might consider them to belong to 
distinct species, were it not for the similarity in the struc- 
ture and colouring of the aperture. In the specimen from 
Ticao, Fig. a, the shell is broader and more acutely ven- 
tricose at the base, and the epidermis is arranged in 
longitudinal streaks ; in that from Luzon, Fig. b, the base 
is somewhat contracted, imparting a more pyramidal form 
to the shell, the apex is dark purple, and the epidermis is 
soft and velvety, uniformly distributed throughout without 
any description of pattern. 
Species 3. (Mus. Cuming.) 
Bulimus lignarius. Bui. testd ovato-conoided, ventri- 
cosissimd, anfractibus senis, tumido-convexis ; colu- 
mella reetd; purpureo-nigricante, epidermide lineis 
faseiisque in anfractu ultimo, et interdum penultimo, 
notatd; aperturd ccerulescente-albd, eolumelld livido- 
purpurascente. 
The wooden Bulimus. Shell ovatcly conoid, very ven- 
tricose, whorls six in number, tumidly convex ; colu- 
mella straight ; purple-black, epidermis, marked with 
bands or lines on the last and sometimes the penul- 
timate whorl ; aperture blueish- white, columella livid 
purple.
