No, 
but tlie bone is dense. On the ventral and 
neural surfaces are many considerable perfora¬ 
tions for nutritive vessels. The ventral sur¬ 
face is concave from front to back and convex 
from side to side. From front to back it mea¬ 
sures A\ inches. From Stretham. Presented 
by Rev. S. Banks. 
2 caudal vertebra from Cottenham. Presented by 
Bev. S. Banks. It is hour-glass shaped; 6 inches 
long, with the intervertebral surfaces very 
slightly concave, 3f inches high, 4 inches wide. 
3, 4 two casts of a claw-phalange from Ely, much 
compressed from side to side, with the articular 
surface rugose and convex from side to side. 
4 inches high, and 2 inches wide; and 5| inches 
long at the base. 
a 5 a dermal plate from Cottenham, presented by 
Bev. S. Banks. It has the form of the side 
plates of a Teleosaurian, with a truncating 
sutural surface at each end, and it is com¬ 
pressed to a sharp border at the back and in 
front. The outer half of the upper surface is 
pitted with large holes, like those on scutes of 
Crocodiles. It is more likely to have belonged 
to Dakosaurus, but may have pertained to this 
genus. 
Over Cabinet lxxxii. are a cast of the fibula, and the proximal 
end of the tibia; both are solid bones. The fibula is 27 inches 
long, somewhat flattened, curved a little towards the tibia, and 
expanded laterally at the articular ends, which are rugose; proxi¬ 
mal end reniform, distal end long ovate. 
The portion of tibia preserved is 17 inches long, gives off a 
sort of patelloid prominence, measures 9 inches in one direction 
and 5J in the other over the rugose sub-rhomboid flattened arti¬ 
cular end.
