GEOLOGY. 



adapted for crushing vegetable food— those of the Halitherium having 

 a resemblance to the molars of Hippopotamus. An interesting series 

 of the fossil remains of Halitherium is exhibited from the Miocene 

 Tertiary beds of Epplesheim, together with Felsinotherium from the 

 Pliocene of Italy ; Bhizoprion from the Middle Tertiaries of France ; 

 may be seen in Wall-case X. 



The true Cetacea {see Wall-case 16) are more fish-like in external 

 form than any other mammals. The nostrils (which may be single or 

 double) are placed at the top of the head, which is generally of dispro- 

 portionately large size, and is never separated from the body bv any 

 distinct external indication of a neck. This family includes the whales, 

 the dolphins and porpoises, the sperm-whales, the ziphioid whales and 

 the Zeuglodons. In these cases are the vertebra, teeth and jaws of 

 Zeuglodon from S. America, and of Squalodon from the English 

 Crag; these animals had double-fauged teeth with conoid crowns. 

 Parts of the hard bony rostra of Ziphius. The ear-bones and vertebra? 

 of whales, &c, may also be seen in Table-cases 11 and 16 : many of 

 them are from the Suffolk and Antwerp Crags, and frcm the phos- 

 phate beds of Charleston, S. Carolina, United States. 



THE PAVILION. 



! ORDER XL— EDENTATA (Sloth and Armadillo). 



Upon a stand in the centre of the floor, very near the entrance to 

 the Pavilion, at the east end of the main Geological Gallery, is placed 

 the cast of the skull and lower jaw, neck-vertebrae, fore and hind 

 limbs, together with the body-armour of an extinct gigantic Armadillo 

 from South America named Glyptodon, the separate bones of which are 

 placed in Wall-case No. 12, and in Table-case No. 14, whilst portions 

 of the actual armour-plates occupy a stand on the east side of the 

 Pavilion. 



The specimen from which the cast is taken measured from the 

 snout to the end of the armour-plated tail, following the curve of the 

 back, 11 feet 6 inches ; the tesselated body-shield being 7 feet in 

 length and 9 feet across, following the curve at the middle of the 

 back. 



These large extinct species differed from the modern Armadillos in 

 having no bands, or joints, in their coat of mail, which enable the 

 living species, when attacked, to contract the body into the form of a 

 ball. The seven-banded Armadillo is less than afoot in length, but the 

 great Glyptodon was so ponderous and bulky that it could not be over- 

 turned, and it only needed to draw up its legs close to its body, so as 

 to rest its carapace on the ground, and bend its armour-plated head 

 down in front, to be perfectly protected on all sides from the attack of 

 any enemy. 



On the stand, in the centre of the Pavilion, is placed the cast of
