SUPPLEMENT TO CRANIA OE RUMINANTS.

[ Genus: HEMIBOS, Falconer. 
(Including Feribos and AmpMbos). 
Plates XX to XXIV. 
In liis above-quoted memoir on Tertiary Ruminants, Professor Riitimeyer has 
pointed out^ that my identifications of Semibos triquetriceros wndL^Amphibos acuti- 
cornis of Falconer are wrong, the skull which I have figured as belonging to the former 
species in Plates XXII and XXIII really belonging to the latter, and one of the 
skulls which I have referred to the latter (Plate XXIV) really belonging to the 
former. Professor Riitimeyer has also pointed out that the skull to which the specific 
name of occipitalis seems to have been applied by Falconer, and which I have figured 
under the name of Feribos occipitalis (Plates XX, XXI fig. 2) is also an aberrant 
form of Kemibos triquetriceros of F^alconer. Additional skulls lately acquired by the 
Indian Museum, had in a great measure convinced me of my erroneous identifications 
previously to seeing Professor Rlitimeyer’s memoir. The new material at hand, 
with Professor Rutimeyer’s memoir, appears to me to warrant the union of the genera 
Hemibos dinA. Ampliibos (and of course Feribosy. Under the former names I formerly 
took the form of the horn-cores as affording grounds for these generic distinctions, 
but now find that these characters are insufficient. 
Species I : Hemibos occipitalis, Falc. sp. Plates XX, XXI, fig. 2, XXI A, XXIV. 
Synonyms : Hemibos triquetriceros. Falconer. 
Leptohos trequetricornis. Pale. Mss. 
Bos occipitalis, Falc. Mss. 
Prohuhalus triquetricornis, Riitimeyer. 
Feribos occipitalis, Lydekker (olim). 
Ampliibos acuticornis, Lyd. (olim). 
The skull figured in Plate XX ® of this volume is so different from the skulls 
of Semibos triquetriceros, figured by Falconer, that with the material formerly at 
hand I was quite unable to identify it with that species, and accordingly adopted the 
specific name of occipitalis apparently proposed for the figured specimen by Falconer, 
with the new affix of Feribos. In the supplemental Plate XXIA I have had drawn 
another skull lately presented to the Indian Museum by the Roorkee (Rurki) Museum, 
which evidently belongs to the same species as the skull drawn in Plate XX. The

2 From a manuscript of Falconer’s lately shown me by Mr. Davies in the British Museum (referred to at page 136 of 
Professor Eiitimeyer’s memoir), it appears that Falconer determined finally to unite the genera Hemibos and Ampliibos 
under the common name of Leptobos, as we find in that MSS. the names L. triquetricornis, L. acuticornis, 
L. antilopinus, and L. elatus. 
^ I have had a reissue of the description of this and other plates issued, in which the specimens bear their new 
names, as well as those under which they are described in the text.
