147—60 CEANIA OE EUMINANTS EEOM THE INDIAN TEETIAEIES. 
Owing to the obliteration of the sutures in all the specimens, the exact boundaries 
of the parietals cannot he determined ; the anterior boundary must, however, have 
been somewhere close to the posterior angles of the horn-cores, so that the parietals 
formed, as I have said, a broad transverse band across the skull, as in the antelopes 
and goats, the frontals being similarly bent on themselves at the intercornual 
ridge. 
The occipital crest forms a wide arch, somewhat flattened above, for a distance 
of half the width of the cranium ; the tuberosity for the attachment of the liga- 
mentum nuchse is large and distinct ; there is a median ridge, dividing the part of the 
occipital surface above the foramen magnum, for the attachment of the intermuscular 
septum of the recti and other occipito-vertebral muscles. The occipital condyles are 
of large size ; the space for the attachment of the digastric muscle is very narrow ; 
the form of the paroccipital processes is not shown in our specimens. 
The supra-orbital foramina are situated far apart from each other, and pierce 
the frontals at right angles ; there is scarcely any sulcus below them ; there are no 
infra-orbital sinusus or fissures as in the true antelopes. 
The palate is highly arched from side to side, and but slightly produced behind 
the last molars ; the molar series are placed nearly parallel to each other ; the 
posterior palatine foramina are situated at the level of the second molars, enthely 
behind the maxillo-palatine suture. 
On the basi-occipital {F. A. S. Plate H, Jig. 6) the posterior tubercles are 
placed immediately in front of the occipital condyles, without any intervening 
groove, and are far apart ; the interval between their internal borders is very nearly 
equal to that between the external borders of the anterior tubercles : the anterior 
tubercles are the smaller of the two ; the posterior are rounded ; the basi-occipital 
is triangular in form, as in the oxen.
