INDIAN TERTIARY AND POST-TERTIARY VERTERRATA. 
VoL. I. 
PREFACE. 
In completing this first volume of the series of the “ Palseontologia Indica,” entitled 
“ Indian Tertiary and Post-Tertiary Vertehrata,” I avail myself of the opportunity 
afforded of making certain corrections and additions, which subsequent investigations 
have rendered necessary, in regard to some of the descriptions. I may mention 
that at tlie time of publication of the second fasciculus, there were contained in the 
Indian Museum only very fragmentary remains of many species, now represented 
by a much larger and more complete series : by the help of these more ample mate- 
rials, I am now enabled in several cases to correct certain errors into which I had 
previously fallen. I may further add that had I had any idea, at the time of publi- 
cation of that fasciculus, that the Indian Museum was at all likely to obtain such 
a magnificent collection of Siwalik vertebrate fossils as now enrich its cases, I 
should not have described remains of different orders in the heterogeneous manner 
in which they are there placed, hut should have devoted a fasciculus to each order 
or sub-order, as has been subsequently done. 
I cannot hut regret that the execution of many of the plates in the second and 
tliird fascicuh is so poor ; it was, however, the best that could be done at the time. 
A change in our arrangements has produced better results in the last fasciculus. 
Three of the worst of the earlier plates have been reissued with the fourth and 
fifth fasciculi. 
In the references given below, and also in the index to the volume, the number 
of the pages refers to the continuous paging of the volume, and not to the separate 
paging of the five component parts.^ The plates, with the exception of the first 
three, have the same heading, “ Tertiary Mammalia,’’ as forming one continuous 
series of illustrations of mammalian remains. The measurements given in this 
volume are all in inches and tenths. 
^ In the first fasciculus, there is of course only one system of paging ; in the second, the volume numbering is at 
the bottom of each page ; and in the succeeding parts, on the outer side of the part numbering.
