to the Pikermi species. A note on this determination has been recently published 
by myself 
Cranium. — Eour views of the cranium referred to above are given in plate A of 
the “ Eauna Antiqua Sivalensis ” (figs. 1, 1 a, 1 b, 1 c). The specimen is fairly per- 
fect, with the exception of the premaxillse and the two zygomatic arches, which have 
been entirely broken away. The skull is completely hornless, and is remarkable for 
the greatly overhanging occiput, and the great relative length of the temporal 
fossse. The specimen shows the whole of the molar series. It is probable that the 
teeth if found alone could not be distinguished from those of some of the following 
genera. The dimensions of this skull are given in the “ Palaeontological Me- 
moirs ” 2 . According to Professor Gaudry the only points of difference between it and 
the skull of the Pikermi specimen of H. duvernoyi , are that the premolars are a 
little larger in proportion to the true molars, that the palatine cleft is not so deeply 
cut, the occipital condyles less prominent, and the pits, on either surface of the 
occipital crest, less deep. These differences do not seem sufficient to justify a specific 
distinction of the two skulls. 
Erom the absence of horns I have placed the belladothere nearer to the giraffe 
than the next genus, as it would seem incongruous to place this hornless genus 
between the Hydaspitherium and the Sivatherium, both of which carry such comp- 
lex horns. As we shall see immediately, however, the structure of the limbs 
shows that the present genus is nearer to the Sivatherium than to the Hydaspi- 
therium. 
Cannon-hones. — Except the skull just described, no remains have been recog- 
nised in India as belonging to this genus, and our comparisons must, therefore, be 
derived from the specimens described by M. Gaudry. 
In figures 4 and 5 of plate XYI1 of this memoir are represented the metatarsus 
and metacarpus of Helladotherium duvernoyi , copied from M. Gaudry’s great work. 
The metatarsus (fig. 4) is seen to be a very stout bone, of thicker proportions than 
the corresponding hone doubtfully referred to Sivatherium (fig. 2). The metacarpus 
is also of a very stout type, hut is considerably larger than the corresponding bone 
of Sivatherium (fig. 1). Its length is 16 inches, and its breadth superiorly 4-28 
inches, and interiorly 3'95 inches. 
It is a stouter and probably shorter bone than the metacarpus of Hydaspither- 
ium (fig. 10), and, therefore, in this respect is more closely related to the Sivatherium 
than is the latter genus, while, as already said, in cranial characters it is nearer to 
the giraffe. 
The discrepancy in the serial position of the helladothere when looked at 
from cranial and skeletal points of view, shows, as we have elsewhere remarked, 
that a strictly lineal classification of the members of this family is impossible, and 
further indicates the probability that the animals under consideration are not an 
ancestral series, as is almost proved by their co-existence in time, but rather that
