left projecting into it in the form of atube. The length 
rarely exceeds two inches and a half. 
It is peculiar to the Marl (blue marl, blue chalk marl 
or gault) between the upper and lower green-sands. 
The small specimens figured are from Folkstone. Mr. 
Goodhall has similar from Maulden and Clophill, and that 
vicinity, in Bedfordshire. We have others from Sussex 
and Cambridge. The large ones are from Speeton Cliff, 
Yorkshire, by favour of Mr. Williamson. 
In Mr. Miller’s figure two furrows are represented 
near the base: we have never seen such a specimen.

BELEMNITES attenuatus. 
TAB, DLXXXIX.—feg. 2. 
Spec. Cuar. Subfusiform, squarish, not much di- 
minished towards the base; suddenly con- 
tracted a little above the middle, whence to 
the rather blunt apex it is elongated and al- 
most cylindrical ; an obscure double furrow 
on each side, and a sulcus in the front ex- 
tending a little way from the base. 
Tus has a curious appearance, one third of it from the 
apex being more cylindrical and much narrower than 
the remainder, and often striated. 
In colour, state of preservation, and every thing ex- 
cept the general form and greater length, this exactly 
resembles the B. minimus: it was found along with that 
species at Folkstone.
