1 foot 10-J inches in breadth. The skull, at first glance, looks 

 like that of some flat-headed form of ox ; but the bones are 

 altogether dissimilar, and the jaws are without teeth. 



Other remains were sent over in 1880, showing that it 

 possessed a tail encased in a horny sheath (see Fig. 58, B), so 

 like the armour-plated tail of the great extinct non-banded 

 Armadillo (Glyptodon) from South America, that had the tail 

 arrived before the head and vertebrae had been received, it 

 might well have been cited to prove the former existence of 

 the Glyptodon in Australia (see "Phil. Trans." 1858, 1S80, and 

 1881). Still further evidence of another species of horned 

 Chelonians, named Miolania platyceps by Owen, has been 

 obtained from a coral sandstone formation on Lord Howe Island, 

 700 miles from the coast of Australia, whence the first specimens 

 were obtained.
