CHELONIA. 
CHELONIA 
FROM THE KIMERIDGE CLAY. 
EnALIOCHELYS CHELONIA. 
Case. Shelf. 
86 f remains of a Chelonian from Ely, mounted 
on a large board, comprising 
9 neural plates, 
12 costal plates, 
scapula, 
right and left coracoid, 
humerus, 
ischium, 
5 caudal vertebrse, 
neural arch of cervical vertebra, 
two marginal plates, 
right and left tibiae and fibulae, 
4 phalanges indicative of terminal claws, 
10 fragments, chiefly of marginal plates 
and plastron. 
Under f are other fragments found with these. 
This remarkable Chelonian presents many affinities. The 
scapula-arch is similar to that of the land Tortoises; the humerus 
is very peculiar, but suggestive of Emydian affinities; the tail is 
long, and suggests Chelydra, there are no chevron bones; the 
carapace is impressed with scutes, but considerable intervals were 
left between the costal and marginal plates, as in the marine 
Chelonians; the plastron was imperfectly developed. 
It appears to have been one of those lost forms which connect 
the now aberrant Sphargis with its allies Trionyx and Emys.
