Inocerami Remains of different species. 
Terebratula sulcata. 
communis. 
Echini Cordated and galeated species, more flattened than 
those in the upper beds. 
Alcyonia. 
Sponges. 
In many parts of this bed are perceived small white ramose forms, pervading 
the chalk, which possibly have been occasioned by some vegetable. 
Fossils of the Blue Marie. 
A first view of the fossils of the blue marie immediately discovers the remains 
of animals differing essentially from those of the superior or inferior strata. I 
have, assisted by Henry Warburton, Esq. compared the fossils of the blue marie 
from Folkstone with those of the pale marie from West Mailing in Kent, and 
with those of the Gault of Cambridge, being enabled to do so by the specimens 
in the collection of the Society; from which it appears that in the arrangement 
of the collection, these fossils have most properly been considered as belonging 
to the same bed. Indeed there are few fossils found at one of these three places 
that are not also found at one or the other of the two remaining places. Similar 
fossils are also found at the foot of the South Downs near to Lewes in Sussex. 
Ammonites splendens . Sowerby. 
auritus . . . Sowerby. 
..... serratus . . Flattish, inner volutions much concealed. Strong* 
slightly bowed prominent rays on the inner margin, 
soon becoming furcated, and passing to the outer 
margin, where they form two serrated edges, between 
which lies the siphuncle. Found also at Cambridge. 
..... subplanus. . Nearly flat, the inner whorls much concealed ; rather 
umbilicated. Curved rays arising in pairs from 
tubercles on the inner margin pass together with 
intermediate rays arising from the middle of the 
whorls to the outer margin, which is tubereulated 
on each side, and flat between. Found also at 
Mailing, and at Lewes.
