SIWALIK AND NARBADA CHELONIA. 
2T— 181 
(No. E 78), whicli most probably came from the Siwaliks of Perim Island as 
“ Greater portion of the carapace and plastron of a species of Emys or Testudo. 
The anterior portion both of carapace and plastron removed, with loss of the most 
characteristic parts. This specimen requires further and careful examination.” In 
1880 the present writeP alluded to this specimen as apparently belonging to Testudo. 
Shell. — The specimen above-mentioned is so imperfect that it has not been figured : 
the only plates that it shows are the 5th vertebral, the right pygal, and the hinder 
marginals and costals of the same side. The union of the carapace and the plastron 
is a bony one ; and the carapace is much vaulted, and shows no trace of any keel : 
the condition of the sutures seems to indicate a fully adult individual, and the 
specimen is evidently distinct from any of the species already noticed. The width 
of the shell is 7*0, and the height of the carapace 3‘0 inches. 
Second specimen. — An imperfect shell, of somewhat smaller size, from Perim Island 
presented to the old India House Museum by Mr. A. Bettington, and now in the 
British Museum, apparently belongs to the same species as the Calcutta specimen, 
but exhibits no characteristic features. 
Third specimen. — Among a collection of fossils from Perim Island sent to the 
writer by Mr. Wajeshankar Gowreeshankar^ is the right half of the shell of a 
tortoise, agreeing so well in size and shape with tlie preceding specimens that it very 
probably belongs to the same species. Unfortunately no trace of the form of the 
plates can be detected, although the bony scutes are distinctly defined : the close 
union of the latter indicates that the specimen is adult. The vertebral scutes are of 
the narrow elongated form characteristic of most of the emydines, and quite 
different from the broad scutes of Testudo : the costals are strongly areolated as in 
Clemmys hamiltoni. 
Affinities. — Assuming that the third specimen belongs to the same species as the 
first., it is pretty clear that the present form is an emydine ; a conclusion confirmed 
by the resemblance in the shape of the divided pygals of the first specimen to those 
of Clemmys hamiltoni. The species is smaller than any existing species of Batagur, 
and may accordingly be provisionally referred to Clemmys. It appears to indicate a 
form not intimately allied to any existing Indian species ; but more perfect specimens 
are needed before anything definite can be decided as to its true affinities. 
Genus II. PANGSHURA, Gray.=^ 
Including Cuchoa, Jerdonella., and Emia, Gray. 
Shell entirely bony, without ligamentous joints : carapace more or less angularly 
elevated and compressed : 4th vertebral plate pointed anteriorly : plastron flat in 
both sexes. 
This genus, both in the recent and fossil state, has hitherto been recorded only
