104—6 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
the whole of the specimens figured are classed under the head of Camelo- 
pardalis sivalensis. The specimens comprise the original type Siwalik cervical 
vertebra (fig. 1) ; another cervical vertebra from Perim already noticed (fig. 2) ; and 
a so-called first cervical vertebra 1 from the Siwaliks (fig. 11), apparently of much 
larger dimensions, and seemingly as large as the corresponding bone of Camelo- 
pardalis giraffa. 
The nomenclature of this large specimen, as well as of some large limb-bones 
figured in the same plate, is a somewhat noteworthy point, as it would lead to the 
inference that the authors of the “ Eauna Antiqua Sivalensis ” had by this time 
abandoned their distinction between Camelopardalis sivalensis and C. affinis. 
In 1876 a notice appeared by myself 3 in which it was concluded that there 
was only evidence of one species of Siwalik giraffe which should be termed C. 
sivalensis „ In that notice a comparison was made between the dimensions of the 
Siwalik cervical vertebra and that of a living giraffe, both measurements being given 
by Messrs. Ealconer and Cautley. Unfortunately it had not been observed that the 
vertebra of the living species was stated to have belonged to a small and not fully 
developed individual ; the comparisons, therefore, fall to the ground, and hence, 
apparently, the conclusions regarding the identity of the two Siwalik species. It will, 
however, be shown subsequently that on other grounds this conclusion must pro- 
bably be maintained. In the course of the above-quoted notice, it was shown that 
the teeth in the collection of the Asiatic Society of Bengal, and now in the Indian 
Museum, doubtfully referred by Dr. Ealconer to Camelopardalis sivalensis , really 
belonge pto some totally different genus. 
Later on in the same year, a portion of the right ramus of the mandible, with 
the last premolar and the first and second true molars, of a Siwalik giraffe was des- 
cribed and figured by myself 3 under the name of C. sivalensis. This jaw and teeth 
were shown to be of considerably larger dimensions than the corresponding parts of 
the skull of Q. giraffa with which they were compared, and the fossil premolar 
was shown to be distinguished by its more elongated form from the recent tooth. 
In 1878 several teeth and jaws of giraffes and giraffe-like animals were de- 
scribed at some length by myself 4 in a paper which will be frequently quoted in the 
course of this memoir. In that notice it was concluded that there was probable 
evidence of the existence of three species of Siwalik giraffes. Subsequently acquired 
specimens have, however, rendered it probable that two of these species must be 
merged in one, while the third probably belongs to another genus. 
The above comprehend the previous notices of this species of any importance, 
and we may now proceed to the description of the specimens forming the subject 
of this memoir. 
1 It would appear from this specimen, which is certainly not an * atlas ’ vertebra, that Falconer’s numbering 
of the cervical vertebrae, comprehends only the vertebrae behind the axis ; hence the vertebra called by him the 
first is really the third, and so on.
