134 NATURAL SCIENCE. Fes., 1893: 
tained to a non-banded armadillo, to which he gave the name of 
Glyptodon. 
While dealing with the South American extinct mammals, Owen 
was also occupied with bones and teeth from the caverns of New 
South Wales, discovered by Sir Thomas Mitchell, and thus he laid 
the foundation of the long series of memoirs on the extinct mammals 
of Australia, for which he obtained materials from Dr. George 
Bennett and many other indefatigable correspondents. Moreover, 
in the midst of this activity, he was collecting materials for an 
exhaustive work on the British fossil mammals, and his charming 
volume on British Fossil Mammals and Birds appeared in 1846. 
Owen also took part in the discussion on the supposed mammalian 
jaws discovered in the Stonesfield Slate, which attracted the notice 
of Cuvier and many contemporaries from 1824 onwards; and it was 
Owen who gave the first extended account of the Purbeck Mammalia 
(collected by Mr. Beckles) in his Monograph of the Fossil Mammalia of 
the Mesozoic Formations (Paleont. Soc.,1871). The only known Lower 
Mesozoic mammalian skull was also described by Owen from the 
Karoo formation of Orange Free State in 1884 (Tvitylodon). The 
Cetacean fossils from the Red Crag formed the subject of a brief 
Monograph of the British Fossil Cetacea from the Red Crag (Palezont. Soc., 
1870); and it must not be forgotten that Owen was the first to 
recognise the affinities of the archaic Zeuglodon. 
Limits of space forbid more. These are merely a few of the more 
salient features of Owen’s contributions to our knowledge of the 
Vertebrata. We need only add that it is very largely owing to the 
prompt manner in which he interested himself in, and dealt with 
every new fossil submitted to him, that the British Museum and the 
Royal College of Surgeons are almost unique in their rich collections 
of Vertebrate Paleontology.
