SUPPLEMENT TO CRANIA OF RUMINANTS.

name triquetriceros^ is extremely misleading and totally inapplicable to the species : I 
therefore propose to aj^ply to the sjDecies the name of ‘^occipitalis,'' originally 
applied by Falconer to the trocboceros form (Plate XX), and wliicli in a wider 
sense may apply to all forms of the species. 
Professor Rtitimeyer has changed the generic name from Semihos to Prohu- 
halus, of which I do not see the advantage ; I propose accordingly that the species 
be known as PLemihos occipitalis, my generic term Pcrihos being dropped. 
Professor Rtitimeyer has pointed ont the great resemblance of the normal form 
of this species to the buffaloes, the species being doubtless a connecting link between 
that group and the antelopes. The same author also includes in his genus the 
living Anoa depressicornis of Celebes under the name of Prohiibaliis celebensis ; the 
resemblance of the normal skulls of Pemihos {Prohuhalus) occipitalis with the skull 
of Anoa is certainly very close ; in the earlier part of this work I pointed out the 
resemblance of Anoa to Amphihos acuticornis of Falconer, which I now include under 
the present genus. If Professor Rtitimeyer is right in this generic identification, it 
appears to me that it would have been simpler to have included both the recent 
and fossil forms under the genus Anoa, and not to have given the living representa- 
tive a new generic and specific name. 
In Plate 1, fig. 1, of his memoir. Professor Rtitimeyer has copied from fig. 4 
of Plate H of the “Fauna Antiqua Sivalensis ” another skull of Memibos occipitalis, 
which he regards as the female form, and which is distinguished by its small cylin- 
drical horn-cores. 
Professor Riitimeyer has also figured and described^ a hornless form of the 
species, from a skull in the British Museum. 
In the text the description of the skull figured in Plate XX given on page 141 
must be taken as that of the trochoceros male form of H. occipitalis, while that of 
the skull figured in Plate XXIV, and described on page 150, must be taken as that 
of the normal male of the same species. 
Species 2 : Hemibos aceticoenis, Falc. sp. Plates XXI, fig. 1, XXI B, XXII, 
XXIII, XXIIIA. 
Synonyms: Amphihos acuticornis, Falc. and Eiit. 
Leptohos acuticornis, Falc. MSS. 
Hemibos triquetriceros, Lyd. (olim). 
The cranium figured in Plates XXII and XXIII of this volume and described 
under the name of Hemibos triquetriceros, has straight horn-cores, with a most 
remarkable triangular cross-section, which are set upon a high frontal ridge. This 
iThe word triquetriceros is a barbarism {triqueter and Kepas), and Professor Riitimeyer has accordingly altered 
it to triquetricornis. It was written triquetriceras by Falconer, wliicb I altered to ceros, like Rhinoceros ; 
Mr. Blanford in the “Manual of Indian Geology” has altered the word to triquetricerve. In the above-quoted 
MSS. in the British Museum Falconer has altered the name to triquetricornis.
