SUPPLEMENTARY NOTES. 601 
We have seen (p. 87) that there is a wider distance between the 
living Genera of the Order Pachydermata than between those of 
any other Order of Mammalia, and that many intervals in the 
series of these animals have been filled up by extinct Genera and 
Species, discovered in strata of the Tertiary series. The Siva- 
therium forms an important addition to the extinct Genera of 
this intermediate and connecting character. The value of such 
links with reference to considerations in Natural Theology has 
been already alluded to, p. 114. 
P. 91. Further light has recently been thrown on the history 
of the organic remains of the Miocene system of the Tertiary 
deposits, by an account of discoveries made in strata of this 
formation in the South of France, near the base of the Py- 
renees. On the 16th of January, 1837, a Memoir was presented 
to the Academy of Sciences at Paris, by M. Lartet, respecting 
a prodigious number of fossil bones that have been lately found in 
the tertiary fresh-water formation, of Simorre, Sansan, &c., in 
the department of Gers. Among these remains are bones of 
more than 30 species, referrible to nearly all the orders of Mam- 
malia. The most remarkable among them is the lower jaw of 
an Ape, which presents the first fossil type of the order Quadru- 
mana yet discovered. The individual from which this jaw was 
derived, was probably about 30 inches high. 
The following is a List of the Genera under which these fossil 
remains are comprehended. 
QuADRUMANA. Simla, one species. 
Pachydermata. Di7iotherium, two species. Mastodon, five 
species. Rhinoceros, three species. One new animal allied to 
Rhinoceros. Palceotherium, one species. Anoplotherium, one 
species. One extinct species allied to Anthracotherium. One 
extinct species allied to Sus. 
Carnivora. Canis, one species. A new Ge7ius, between a 
Dog and a Raccoon, one large species. Felis, one large species. 
Genetta, animal allied to. Coati, animal allied to Coati, large 
as a White Bear. 
RoDENTiA. Lepus, one small species. Many other small 
species of Rodents not yet determined.
