which now skirts the foot of the Himalayahs, it would soon have 

 been exterminated by the large feline fera?, by the hyeenas, and 

 large predaceoiis bears which are known to have been members of 

 the old Sewalik fauna. 



Postsci'ipt. — Since the above remarks were submitted to the Society, 

 M. Duvernoy's paper, embodying two communications read to the 

 Academy of Sciences on the 19th May and 27th November last, has 

 appeared in the January Number of the ' Annales des Sciences Na- 

 turelles.' These notices were published in the ' Comptes Rendus,' but 

 were unknown to the authors at the time. M. Duvernoy describes 

 the lower jaw of a fossil giraffe found in the bottom of a well, lying 

 on the surface of a yellow clay, along with fragments of pottery and 

 domestic utensils, in the court of an ancient donjon of the 14th cen- 

 tury in the town of Isoodun, Departement de I'lndre. Considerable 

 doubt remains as to the bed and source whence the fossil was de- 

 rived. M. Duvernoy attributes the jaw to a distinct species of 

 giraffe, which he names Camelopardalis Biturigum. Professor Owen, 

 from the examination of a cast, confirms the result, expressing his 

 conviction " that in the more essential characters the Isoodun fossil 

 closely approaches the genus Giraffe, but differs strikingly from the 

 (single) existing species of the south and east of Africa, and that the 

 deviations tend towards the subgenus Elk." 



M. Duvernoy also mentions the discovery of a tooth in the mo- 

 lasse near Neuichatel, by M. Nicolet, determined by M. Agassiz to 

 be the outer incisor of a fossil giraffe. — (Duvernoy , Annales des Sciences
