Powis’ BiTLiinis. Shell acuminately oblong, thick, ob- 
tuse at the apex, whorls smooth, shining, scarcely 
striated, columella slightly arched, aperture rather 
small, a little effused, lip thickened, but slightly 
reflected; fulvous bay, conspicuously painted with 
irregular, oblique, blackish-green streaks, and a single 
belt round the last whorl, sometimes unspotted, with 
the belt only, lip, and columella deep purple violet, 
peritreme blackish, apex reddish chesnut.

This very beautiful and rare species approximates in n 
manner to the B. regina which follows ; it is of a less 
acuminated form, of extremely solid structure, and, ex- 
cepting the lip and columella, the pattern of colouring is 
dissimilar. Of the specimens here represented, that from 
the collection of Mr. Dennison is distinguished by its rich 
painting of irregular black-green stripes upon a fulvous- 
bay groimd ; in Mr. Cuming’s specimen the ground colour 
is unspotted, but in both examples the last whorl is en- 
circled by a characteristic narrow belt of the same dark 
colour as the stripes.

The queen Bulimus. Shell somewhat elongately oblong, 
often simstral, spire pyramidally acuminated, obtuse 
at the apex ; whorls seven to eight in number, smooth 
or obliquely finely striated, columella slightly twisted, 
lip simple; fulvous white, whorls variegated and 
articulated at the upper part with brown or green, 
greenish, or purple-black at the lower, apertme and 
columella sometimes white, sometimes deep violet, 
edged with black.

It wdl be seen by the above-mentioned localities that 
the Bulimus regina inhabits a wide range of country, and, 
by the figures, that it is found under very different aspects, 
having in some localities a dextral, in others a sinistral 
growth. 
I quite agree with M. D’Orbigny in the propriety of 
referring this species to the genus under consideration 
rather than to Acliatina ; the columella is never strictly 
truncated, and the shell has aU the texture, form, and 
coloiiring of a Bulimus. 
Pigure 90 b. (Mus. Dennison.) 
Bulimus zebra. This species is also found under so 
many different aspects, that I thought it desirable to figure 
a singular variety from the collection of Mr. Dennison, of 
which that gentleman possesses several examples exactly 
similar, brought by some vessel into Liverpool, but he 
is not aware from whence. It is of a remarktably solid 
growth, heavy as porcelain, and has no indication of the 
green which predominates more or less in most varieties. 
The upper part of the whorls is white, the lower encircled 
by a broad band of light rust colour, and towards the 
aperture the whorl is crossed by numerous concentric dark 
streaks.
