The under surface of the palatal process of the maxillary hones is 

 rugose, as in the Peccari ; the portion of the skull, including the inter- 

 maxillary hones and the incisive teeth, is unluckily broken oft' and lost. 

 That the eye was full and large, is indicated by the size of the optic 

 foramen and the capacity of the orbit, the vertical diameter of which 

 equals one inch. 



The upper part of the cranium anterior to the sagittal suture is 

 slightly convex from side to side ; its longitudinal contour is nearly 

 straight. The face gradually becomes narrower anteriorly ; it is slightly 

 concave at the sides. 



The general form of the skull was probably intermediate in character 

 between that of the Hog and the Hyrax. The large size of the eye must 

 have given to the physiognomy of the living animal a resemblance to 

 that of the Hare and other timid Rodentia. 



1083. A dorsal vertebra of a small mammiferous quadruped, agreeing in size 

 with the Hyracotherium leporinum, and from the same stratum and 

 locality. Presented by William Richardson, Esq., F.G S. 



Genus Anoplotherium. 



1084. A portion of the alveolar series of the left ramus of the lower jaw of the 



Anoplotherium commune, Cuvier, with five of the molar teeth in situ : the 

 inner surface of their crowns are exposed to view. 



The specimen is imbedded in a block of gypsum, and is most probably 

 from the quarries at Montmartre. Hunterian. 



1085. A portion of the left ramus of the lower jaw, with the penultimate and 



part of the antepenultimate and last molars in situ. It is imbedded in a 

 block of gypsum. 



From the Eocene quarries at Montmartre. 



1086. A cast of the skull, in profile relief, of the Anoplotherium commune, with 



the series of teeth complete in both the upper and lower jaws.
