group), long nosed, and armed only with small nasal 

 bosses, or a very weak horn. Nasal cartilages attached by 

 bony studs, capable of motion, but tending to fuse at 

 maturity, owing to longer nose and weaker horn. (Best 

 known example: Nototherium tasmanicum.) 



The remaining members of this group arc — Noto- 

 therium victoria, Owen; Euowenia grata, De Vis; 

 Euowenia robusta, De Vis. It is apparent to us that the 

 jaws Professor Owen thought might be those of a female 

 come within this group, but their exact position is un- 

 certain. 



It is unfortunate that De Vis' nam- Euowenia, is 

 later in time than victories, as it would have made a nice 

 bins to have called this group by that name. The word

cause misconc ptiona to arise respecting it, and tasmani-

 if it were suitable for such a group — which, ol coarse, it 

 is not! Accordingly, we leav the group to its Lepto- 

 cerathi onlj using Xototherium tasmanicum as

 described fragments of jaws and skulls from the plei 



ap heaps of Nature. A single illustration will 

 make clear our meaning. Do Vis always thought that 

 the oval, tul !. premolar oJ the upper jaw would 



be opposed by a similar tooth in the mandible, and the 

 narrow elongated tooth that really does oppose it he 

 considered generically distinct! Such are the surprises 

 that Nature springs upon us, that it was only with the 

 finding of associated jaws in 1910 that any accural;' data 

 existed upon the subject. Our latest Sin it lit on find — 

 armed with a full set. of unworn teeth — displays the won- 

 derful manner in which the elongated, triangular pre- 

 molar of the lower jaw exactly tils the inner two-thirds 

 of the large, oval, upper premolar — the outer third of 

 that tooth in unworn specimens forming only part of the
