308 Mr. R. Etheridge, Jnr., on 



Mr. Gerard Krefft, a former Curator of the Australian 

 Museum, referred to his M. australis on, at least, four 

 separate occasions. The first reference I have been able to 

 light upon is contained in one of our Museum publications — 

 ' Guide to the Australian Fossil Remains exhibited by the 

 Trustees of the Australian Museum, and arranged and named 

 by Gerard Krefft/ &c.*, wherein we read : — 



" Order Endentata. 

 " Genus Mylodon ? 



" Mylodon ? australis, Krefft. 



" The presence of some animal, allied to the above extinct 

 American genus, is indicated by a single terminal phalanx, 

 or nail-bone, with its peculiar protecting bone, partly 

 broken "f. This phalanx was obtained from the ossiferous 

 deposit of the celebrated Wellington Caves, New South 

 Wales. 



The second reference appeared in Krefft's 'Australian 

 Vertebrata — Fossil and Recent ' J, as follows : — 



"Edentat a. — Sloth Tribe. 

 " Mylodon. 



" Mylodon ? australis" 



with similar remarks to those already quoted. This phalanx 

 must have come into Krefft's possession between 1867 and 

 1870, because there is no mention made of it in the first 

 edition of the 'Australian Vertebrata' §. 



The third reference is of a controversial nature, and is 

 coutained in " A Cuvieriau Principle in Palaeontology tested 

 by evidences of an Extinct Leonine Marsupial (Thylacoleo 

 camifex), by Professor Owen, • &c. Reviewed by Gerard 

 Krefft/' &c. || . Confining our attention to that portion of
