Dr. John Collet to the Bishop of Ossory, F.R.S., which is printed in the 

 Philosophical Transactions for the year 17&7, P- 109. In the list of 

 organic remains are included " A great many horns, heads, and bones of 

 several kinds of Deer, the horns of the Antelope, the heads and tusks of 

 Boars, the heads of Beavers, &c." 



It is most probable that the specimens Nos. 211 and 212, the latter of 

 which is recorded to have been found in a moss-pit in Berkshire, are 

 from the celebrated peat deposit atNewbury. 



Genus CJueropotamus. 



1080 A cast of the mutilated basis cranii and upper jaw of the Charopotamus 

 Cuvieri, Owen. It demonstrates the two glenoid articular surfaces, which 

 are fiat as in the Peccari ; the two zygomatic arches, which also 

 resemble those of the Peccari in their great width and rectilinear direc- 

 tion : the specimen likewise exhibits the posterior part of the palate, 

 the pterygoid processes, the three posterior or true molars on each side, 

 three of the four premolar teeth, the second being absent on the right 

 side and the third on the left side. A part of the orbit is preserved on 

 one side, demonstrating the position of the eye. 



The two anterior premolars are separated by a vacant space and have 

 simple compressed crowns, the fourth and fifth have each two tubercles 

 and a basal ridge. The crowns of the true molars are square-shaped 

 and support four principal tubercles in two transverse pairs, with a 

 smaller one at the interspace of each pair, the whole being surrounded 

 by a strong basal ridge. 



From these characters Cuvier established a new genus of Pachyderms 

 more nearly allied to the Hog-family than to the Anoplotherium. The 

 Chaeropotamus apparently bore a close affinity to the Anthracotherium, 

 by which it was connected with the Hippopotamus. 



The original of this cast was discovered in the Eocene gypsum quarries 

 at Montmartre, and is described in the ' Ossemens Fossiles,' ed. 1822, 

 torn. iii. p. 262. pi. lxviii.
