INDIAN TERTIARY AND POST-TERTIARY YERTEBRATA. 
SUPPLEMENT TO CRANIA OF RUMINANTS, 
By R. LYDEKKER, b.a., 
GEOLOGICAL SURVEY OF INDIA. 
(WITH SUPPLEMENTAL PLATES XXIA AND B, XXIIIA, AND REISSUE OF 
PLATES XXI AND XXIV). 
The addition of several skulls of Siwalik antilopoid Bovidse to the collection 
of the Indian Museum, and the publication of an important memoir on Tertiary 
lluminants by Professor Riitimeyer,^ have shown me that in the “ Crania of Rumi- 
nants” my identifications of the specimens in the Indian Museum with the genera 
Remibos and AmpJiihos of Palconer were generally erroneous, and also that the new 
genus Feribos cannot stand. The first part of Professor Riitimeyer’s memoir was 
published previously to my own, hut unfortunately had not reached India at the 
time of publication of the latter ; the second part was published later than my own 
memoir, of which it contains a review, and points out the errors into which I had 
fallen. In my memoir I referred to the extreme difficulty of recognizing Pal- 
coner’s species of Bovidse merely from the figm?es in the supplemental plates of the 
Pauna Antiqua Sivalensis,” without access to the original specimens, and I at one 
time thought of discarding Palconer’s names and applying new ones of my own. 
The identification of Palconer’s species from the original specimens in the British 
Museum by Professor Riitimeyer has now rendered these species distinctly identi- 
fiable, and I, therefore, must now alter the names of my wrongly identified species. 
I, however, for reasons given below, do not adopt the names assigned by Professor 
Riitimeyer. I have reissued descriptions of the plates of the wrongly identified 
skulls, with their new names, as well as those under which they were first described.
