ANOPLOTHERIUM AND GIRAFFE. 191 



mineralized and rendered nearly crystalline by the infiltration 

 of siliceons or ferruginous matter, and acquires a corre- 

 sponding hardness, or tinge of iron, with increased specific 

 gravity. The matrix in contact with the bone is rendered 

 compact and crystalline in texture. The remains in this 

 state have been designated by the authors as the ' hard 

 fossil.' 



The remains of Anoplotherium and of the larger species 

 of Giraffe, described in the present communication, belong 

 to the ' soft fossil ; ' those of the smaller species of girafie to 

 the ' hard fossil.' 



Anoplotherium. — The occurrence, in the Sewalik deposits, 

 of bones belonging to this genus, was announced by the 

 authors in their ' Synopsis of the Fossil Genera from the 

 upper deposits of the Sewalik hills,' published ui vol. iv. of 

 the JoTunial of the Asiatic Society of Bengal, in the year 

 1835 ; and the same fact was afterwards referred to in 

 vol. vi. p. 368, of that journal. In these communications the 

 species was not described, but was named provisionally, A. 

 poster ogenium. In a communication made to the Geological 

 Society in the year 1836, descriptive of a quadrumanous 

 fossil remain, and published in vol. v. of the second series 

 of their ' Transactions,' the same species was mentioned under 

 the name of A. Sivalense, a term which the authors propose 

 to retain, in accordance with the principle they adopted in 

 the cases of the horse, camel, hippopotamus, &c., of con- 

 necting the most remarkable new species of each fossil Se- 

 walik genus with the formation itself. 



In their present communication the authors purposely ab- 

 stain frora entering on the anatomical characters of this new 

 species further in detail than is barely sufficient for its deter- 

 mination ; and they therefore confine their notice to two fine 

 fragments of one head, one fragment (PL XVII. fig. 1) be- 

 longing to the left upper jaw; the other fragment (PI. XYII. 

 fig. 2) to the right upper jaw. 



By a happy chance the teeth are beautifully preserved. 

 The age of the individual, which was just adult, was the 

 best that could be desired to show the marks characteristic 

 of the genus ; for the teeth had attained their full develop- 

 ment, though the two rear molars had hardly come into use. 



Plate XVII. fig. 1, is a horizontal view of the left upper 

 jaw comprising the six back molars. These teeth were sub- 

 jected to a rigid comparison with a cast from the jaw of 

 Anoplotherium commune, figured by Cuvier in vol. iii. of the 

 ' Ossemens Fossiles ' (Plate XL VI. fig. 2), and also with casts 

 from the corresponding molars of Ghalicotherium Goldfussi, 

 figured by Kaup in the second 'livraison' of his ' Ossemens
