SCAPHITES obliquusr 
TAB. XVIII . — Figures 4 5 5 5 0 3 and 7 , 
Spec. Char. Obliquely involute, unibilicated^ inner 
whorles concealed,, covered by transverse strise, 
dividing into two or three near the outer half 
of the wborle, which is rather flatfish and 
broaef and uniting again on the other side. 
The obliquity of the curve of this shell, and the smallness 
of those striae or radii that cover the last whorle, are the 
characters that distinguish this from the last. The last 
whorle is much incurved. Length nearly an inch, width 
about three-fourths of an inch, greatest thickness half as 
much. A specimen, or rather a cast, found in the hard 
chalk near Warminster, in possession of Miss Bennet, 
measures an inch and a quarter in length. 
The specimens here figured are from Hamsey Marl pit 
near Lewes, in Sussex. I was favoured with them by 
G. A. Mantell, Esq. and I am happy to show that this 
rarity is found in the maiiey stratum, as well as in the 
chalk, in the neighbourhood of Brighton. I have given 
two views, the one a profile, the other a more dorsal one, 
to show that the transverse striae are narrower at the smaller 
spire, and wider as they approach the returning spire, 
where they are about twice as distant. The left hand 
lower figure shows a front view and the obliquity of the 
spire. The segment on the right hand was broken off 
to show the concamerations, but very little of them are 
perserved. 
The contour of the shell should have been shown more 
swelled in the middle of the figure.
