PREFATORY REMARKS. 
This Catalogue has been undertaken with a view to endeavour 
to ascertain the extent of the various collections of vertebrate 
Fossil remains which have, at different times, been presented to 
the Asiatic Society of Bengal. 
No separate record of these presentations appears to have been 
ever kept by the Society ; nor, strange to say, has the correspon- 
dence of the Donors been preserved ; so that nothing, in the 
shape of information regarding them is now accessible, besides 
the notices often brief and scanty in details contained in the 
Proceedings as printed in the Journal. 
The collections may be classified under two heads, viz. Indian 
and Foreign. 
The most important of the Indian, may be arranged con- 
veniently in a Geographical order thus, the collections, from 1st, 
Ava; 2nd, The Sewalik Hills; 3rd, The Valley of the Ner- 
budda ; 4th, Perim Island and the Gulf of Cambay ; 5th, Scinde ; 
6th, The Alluvium of the Jumna River; 7 th, A few specimens 
from the Delta of the Ganges, and from the Banks of the Betwa 
River. 
The foreign collections are of less importance. They consist : 
1st, of a few Enaliosaurian remains probably from the 
English Lias, but they bear no marks, nor has any information 
been found out regarding them ; 2nd, some Clielonian remains 
of very modern aspect from the Mauritius ; 3rd, a very inter- 
esting series of Reptilian remains from the older secondary 
strata of the Cape of Good Hope, consisting chiefly of bones of
