145—58 CEANIA OE EUMINANTS EEOM THE INDIAN TERTIAEIES. 
In the approximation of the bases of the horn-cores, and in the separation 
of the occipital and parietal planes, the skull makes some approach to the skulls of 
the goats ; the position of the highest point of the frontals, almost midway between 
the orbit and the occiput, is an antelopine character ; the large size and distinctness 
of the posterior tubercles of the basi-occipital is also a character of that group ; 
the general form of the basi-occipital, however, and the structure of the teeth, 
is essentially Bovine. 
Genus: HEMIBOS, Falconer. 
This genus was made by Dr. Ealconer for the reception of an aberrant Bovine 
cranium from the Siwaliks ; the name, however, only has been published, no 
description having ever appeared. 
The genus may be shortly defined as follows, from the characters of the 
cranium : — 
Erontals concave, broader than long : horn-cores triangular in cross-section, short 
and straight, situated below the occiput on a high ridge of the frontals ; occipital 
and parietal planes distinct : facial longer than frontal portion : orbit and horn-core 
approximated. Teeth and basi-occipital of the Bovine type. 
Hemibos TRiQUETiiiCEiios, Falconev. Pis. 22 and 23. 
Eigures of the cranium of this species have been engraved among the un- 
published plates of the “Eauna Antiqua Sivalensis” {Plate 11), and a few measure- 
ments are given in the accompanying index ; another figure of the cranium will be 
found in Boyle’s “ Himalayan Botany ” {Plate VI, Jig. 5): no detailed description 
has, however, apj)eared. 
The cranium figured here {Plates XXII and XXIII ) was collected by Major 
Godwin- Austen in the Siwaliks of the Markanda Biver ; the greater portion of the 
specimen is complete, though somewhat weather-worn ; about one-half of the left 
horn-core remains, while the whole of that of the right side is broken away : the 
distal portion of the maxillae, together with the whole of the premaxillse and the 
nasals, are also wanting. The palate is nearly free from matrix, and shows the roots 
of the molar series of either side, the crowns of all the teeth having been broken off 
close to their alveoli; the spheno-palatine region is somewdiat imperfect. The 
cranium is that of a fully adult animal, nearly all the sutures having been 
obliterated. 
If we turn to the profile view of the cranium given in the accompanying 
lithographs {Plate XXIII), we find this aspect to be totally different from the 
corresponding aspect of the crania of any of the Bovines described above, and, as 
will be more fully noticed below, approaching the form of the crania of the goats.
