has also similar impressions of veins, the granulated sur- 
faces of the lamina it is composed of alone distinguish it. 
Of this species we have seen three individuals ; one 
from Bridgwick Pit near Lewes, and another from Ando- 
ver, both collected by H. H. Goodhall, Esq.; one of them 
shows the reticulated structure exposed by decomposi- 
tion, the other the worn base in its progress towards Ac- 
tinocamax: the third is in Mr. Mantell’s collection. We 
have shown a view of its base at fig. 5. 
This species occurs also in St. Peter’s Mountain, 
near Maestricht. 
BELEMNITES lanceolatus. 
TAB. DC.—/igs. 8. & 9. 
Spec. Cuar. Subfusiform, much elongated, gra- 
dually tapering to a point, an obscure double 
furrow on each side, base obscurely trian- 
gular. 
A mvucu more elongated shell than B. plenus, which it 
much resembles ; its base is but slightly expanded, the 
surface smooth; length three inches and a half, diameter 
four lines. : 
G. Mantell, Esq. has kindly lent us one, and H. H. 
Goodhall, Esq. another specimen of this elegantly 
shaped Belemnite: they are both from Hamsey; the 
first has a convex, the other a conical base, with a small 
portion of the original cavity remaining, which is fre- 
quently the case with individuals of other species that 
would be referred to Actinocamax by Mr. Miller. 
We have fragments from Chute Farm that seem to 
belong to this species.
