canines and an unbroken series of teeth (No. 1086), and to which Cuvier 

 gave the name of Anoplotherium commune. See the detailed descrip- 

 tions of these bones in the above-cited edition of the ' Ossemens Fos- 

 siles,' torn. iii. 



1104. The head and a considerable portion of the shaft of the thigh-bone of 



the Anoplotherium commune, Cuv. ; it shows the well-developed and cha- 

 racteristically situated small trochanter. The specimen is partly imbed- 

 ded in a block of Montmartre gypsum, from which it was relieved by the 



Donor, William Clift, Esq., F.R.S. 



The following casts of the bones of the Anoplotherium, from No. 1 105 to 1 1 17 

 inclusive, belong to the same left fore foot, and were presented to the College 

 by Baron Cuvier. 



1105. The astragalus of the Anoplotherium commune. The anterior surface is 



divided by a vertical ridge into two articular surfaces, more unequal 

 than in the Hippopotamus and the Ruminantia, and less unequal than 

 in the Hog ; it most resembles that of the Camel. Besides the broad 

 inferior articulation with the calcaneum, it interlocks with that bone by 

 a peculiar bent process continued from the posterior, inferior and outer 

 angle, which Cuvier states he had not found in any other animal. 



1106. The calcaneum of the Anoplotherium commune '. it presents superiorly a 



convex articulation for the support of the fibula, anteriorly a surface 

 twice as long as broad for the os cuboides, and internally two vertical 

 articular surfaces, besides the broad horizontal one, for the astragalus. 

 These characters, Cuvier observes, are met with only in the calcanea of 

 the even-toed Pachyderms, as the Hippopotamus, the Hog-tribe, and 

 the Ruminantia. 



1107- The os cuboides of the Anoplotherium commune: it presents anteriorly a 

 singular articular surface for a metatarsal bone, and is distinct from the 

 scaphoid, as in the Pachyderms and Camel-tribe. In the true Ruminantia 

 these bones are anchylosed together.
