 MELANTIA striata. 
TAB. XLVI. 
Spec. Cuar. Length about 24 times as long as the 
greatest diameter. Whorls six or more, with 
about sixteen rounded or spreading carine, 
nearly equal on the outer part of the whorls, 
but widened in the concealed parts. 
Turis shell appears sometimes to exceed eight inches in 
length; the surface is smooth, with sixteen sharpisli lon- 
gitudinal stria, and as many rounding projections. 
The upper part of this figure is taken from a specimen 
found at Lymington, Somersetshire, and sent me some years 
since by my late Friend Mr. W. Cunnington; the lower 
part from one found in what is called the Coral rag stratum at 
Goat-acre, Wiltshire, by favour of the Rev. H. Steinhauer 
in 1813. I have placed the two pieces together to show the 
appearance and size of a more perfect whole ; they accord so 
well that one might seem to have been broken from the other, 
and the wearing of the specimens also accords, for the upper 
part of the under specimen has almost lost the appearance 
of striw, while the upper specimen is so worn that it would 
have hardly been recognizable as the same species, were it 
not for the agreement in the proportions and the striz on 
the under side. Geologists will know whether they are
