The chain of proof, strong enough as it is to secure assent, 

 will be completed when a cranium of Nototherium with mandible 

 attached is unearthed, as I feel assured it will be in course of 

 time. 



Though Zygomaturus is thus proved to be distinct from 

 Notothenimi its differential characters are not strong enough to 

 erect it into a separate family — but, associated with its three 

 allies, Diprotodon, Nototherium, and Euowenia, it forms a 

 natural family of the phascolomine section of the marsupials. 

 To this we cannot consistently yield an exclusive claim to the 

 name of Diprotodontidas ; I therefore once more suggest a name 

 derived from the second genus in order of discovery and preva- 

 lency, and call it Nototheriida. 



The representative of the femur of Zygomaturus found with 

 the skull, confirms the conclusion that the animal belonged ta 

 the Phascolomine stirps, but gives little additional information 

 — its distal end is the only part from which ideas of form and 

 size can be derived — the pronounced gibberosity of the epiphysis 

 over the inner condyle is here seen in a greater degree than in 

 Diprotodon — measured across the condyles the bone is 167 mm. 

 in breadth — its depth from the summit of the tuberosity is 

 133 mm. — the rest of the bone is partly mutilated, partly 

 deformed, by some crushing force to which it has been exposed.
