XXIV. INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
SIWALIK BIRDS. 
Distribution of Struthio. — In reference to tlie distribution of 8. camelus and 8. 
asiaticus {infra, pp. 144-5) it may be observed that Professor A. Newton^ mentions 
that the existing species formerly occurred in Assyria, and that it may still exist in 
the Kirwan district of eastern Persia, whence it may stray into Turkestan ; it is 
also stated that there are assertions of its former occurrence in Sind and Baluchistan, 
but these are insufficiently authenticated. This evidence is extremely important as 
connecting the distributional areas of the recent and fossil species. 
Dromaeus. — Among the Siwalik collection in the British Museum the writer has 
found specimens which have convinced him that the phalangeals described on pp. 
145-6, and figured^ in pi. XIV. figs. 2, 4, 5, 6, under the name of Dromceus (?) 
sivalensis really belong to an ungulate mammal allied to Hippopotamus. 
SIWALIK AND NARBADA CHELONIA. 
8pecies of Batagur. — It may be mentioned that the so-called B. iravadicus, Ander- 
son® is omitted from the lists of Batagur given on pp. 187 and 195, since it presents 
no characters by which it can be palseontologically distinguished from B. trivittatas, 
with which Mr. Tlieobald^ thinks it may be identified.® For the smaller species 
referred by Dr. Anderson to Batagur, Mr. Theobald retains the genus Morenia. 
Trionyx, sp. — Attention may be directed to the redetermination on page 255 of 
the specimens described and figured on page 206. 
SIWALIK CHELONIA, OPHIDIA, AND LACERTILTA. 
The name Gharialis. — The writer follows Mr. Theobald® in adopting the name 
Gharialis in place of Gavialis, which was founded on a misspelling of the native 
name gharial : the retention of the h in the first syllable cannot, however, be defended 
in strict Latinity. 
Eocene pythons . — On account of differences in the vertebrae Python cadurcensis 
{infra, p. 237) has been made the type of the new genus Paleeopython, Rochebrune’’ ; 
a second species from Quercy being described in the same memoir under the name 
of P. filhoti. Pictet’s Swiss forms are referred to the same genus.

tion, 1884, p. 5.
