BULIMUS.— Plate X. 
flamed with wliite, encircled round the lower part 
with a dark line or narrow hand, sometimes with a 
white band beneath the sutures peculiarly abraded 
here and there, columella and interior of the aperture 
bluish white, peritreme edged with chesnut-black.

There is a singular peculiarity attending this species in 
the mamier in which the epidermis, especially on the 
band which is sometimes seen beneath the sutoes, is 
abraded, denuding the shell in patches.

Bolimus leopakdes. Bui. testa subahbreviato-ovatd, 
ventricosd, anfractibus quinis, convexis, Imigitvdimliter 
creberrims costulato-striatis, ultimo spirts longitudinem 
superante, columelld arumtd, aperturd amplissimd ; 
luteo-castaned, epiderndde albidd spared, sub alternd

The leopaed Bulimus. Shell somewhat shortly ovate, 
ventricose, whorls five in number, convex, very 
closely sculptured longitudinally with fine rib-like 
striae, last whorl exceeding the length of the spire, 
columella arched, apertui'e very large ; yeUowish- 
chesnut, variegated with a sciittered whitish epider- 
mis upon a thin horny one, peritreme purple-chesnut.

This remarkable species, of which Mr. Cuming has only 
the single specimen here represented, is distinguished &om 
all others by the effused and suddenly enlarged develop- 
ment of the last whorl. It is also characterized by a 
regular succession of longitudinal rib-like striae of a more 
defined growth than the ordinary lines of structure, which 
in a genus so devoid of sculpture is an important feature. 
The name is suggested by the scattered interrupted 
stripes in which the outer hydi-ophanous epidennis is de- 
posited. The columella, it should be observed, has a 
pinky hue, and the impress of the striae imparts a delicate 
satiny irridescence to the interior of the shell. 
Species 52. (Mus. Cmning.) 
Bulimus concinnus. Bui. testd pyramidali-oblongd, an- 
fractibus senis plam-comexis, aperturd contraetd, labro 
rejlexo ; castaneo-fused, epidermide concimte albido- 
marmoratd et flammatd, columelld el apertures fauce

The peetty Bulimus. SheU pyramidally oblong, whorls 
six in number, flatly convex, aperture contracted, lip 
reflected ; chesnut-brown, epidermis prettily flamed 
and marbled with white, columella and interior of the 
apertm-e bluish white, peritreme dark chesnut.

I much doubt whether this is anything more than a 
variety of the B. leucophsa ; it is, however, a well-marked 
and extremely pretty one.
