other ; and it is probable that the posterior protuberances of the fore- 

 head also supported a pair of short massive horns. 



The living Sivatherium must have 

 resembled an immense Gnu or Ante- 

 lope, with a short, thick head, and an 

 elevated cranium crested with two pairs 

 of horns; the front pair small, the 

 hinder large (perhaps palmated), and 

 set behind as in the Aurochs ; it had 

 small lateral eyes, great lips, and a 

 nasal proboscis, an organ unknown 

 in all living ruminants. The model 

 of another species (S. Perimense), is 

 deposited in the same Case.

There are likewise remains of a species of Giraffe, from the same

 respecting them. 



CHAPTER V. PART V. 

 FOSSIL CEPHALOPODA. 



FOSSIL CEPHALOPODA. Table-cases on the south side of Room V. The 

 six Table-cases on the right of the entrance from Room IV. are devoted 

 to the fossil Cephalopoda, and contain an extensive collection of Am- 

 monites, Nautili, and other shells of the mollusca of this order. 



The Cephalopoda are composed of a body which is either naked, as in 

 the Sepia or Cuttle-fish, or enclosed in a shell, as in the Nautilus and 

 Argonaut ; with a distinct head, eyes as perfect as in the vertebrata, 

 complicated organs of hearing, and a powerful masticatory apparatus, 

 surrounded by arms or tentacula. Below this head there is a tube, 

 which serves as a locomotive instrument to propel the animal backwards 

 by the ejection of water which has served the purpose of respiration, 

 and can be thrown out with considerable force by the contraction of 

 the body. The fossil remains consist of the external shell, and the 

 internal osselet of the Sepiadse, and rarely of the body and arms, ink- 

 bag, mandibles, &c. as in some splendid examples from the Oxford 

 Clay of Wiltshire, in this collection.
