SUPPLEMENT TO CRANIA OE RUMINANTS.

the horn-cores are smaU and suh-cylindrical, the orbits not prominent, and there is 
not the high frontal ridge so characteristic of the skull of the male (Plate XXIII). 
The cranium, of which a profile view is given in Plate XXI, fig. 1, and a front 
view in Plate XXIB of this volume, agrees very closely with the above-men- 
tioned skull, and belongs probably to a young female of the same species. The 
description of the skull given on pages 145 to 148 of this volume must be taken 
as that of the male skull of this species ; the female skull drawn in Plate XXI, 
fig. 1, and Plate XXIB is not fully described. 
Species III : Hemibos antilopinus. Pale, sp, MSS. 
Synonyms : Vrohuhalus antelopinus, Riit.

On page 89 of this volume, I mentioned that I had no means of identifying 
Ampliihos antilopmus of Palconer, and therefore abandoned the name. Among the 
Siwalik fossils in the British Museum, Professor Rlitimeyer has, however, found a 
skull of a bovoid ruminant, which he says ^ seems to be that of Ampliihos or {Lepto- 
bos) antilopinus ^ of Palconer, and which he has figured in liis memoir ® under the 
name of Lrohuhalus antelopinus. Professor Rlitimeyer also mentions that he is not 
certain whether the skull be that of a male or female individual. The horn-cores are 
subpyriform in cross-section, thereby approaching to those of the trochoceros male of 
Remihos occipitalis, and the orbits prominent, which is also a character of the latter 
species as opposed to R. acuticornis. It is worthy of note, as indicating the generic 
identity of all these animals, that whereas R. 'antilopinus was placed at first by 
Palconer in his genus Ampliihos, it is placed by Rlitimeyer in Remihos {Prohu- 
halus). 
Genus: LEPTOBOS, Pale. MSS. 
Species : Leptobos palconebi, Rlitimeyer.

Professor Riitimeyer has described and figured^ several skulls of another 
bovoid ruminant in the Siwalik collection of the British Museum, under the name 
of Leptobos falconeri, mentioning that it is very possible that these skulls belong to 
Ampliihos {Leptobos) elatus of Palconer. Three of these skulls are drawn without 
any name, in the unfinished Plate S of the supplement to the “ Pauna Anti qua Siva-
