existing species. The form is still met with in the district, though 

 by no means common even in the mountainous regions, while in 

 most of the settled parts it appears to be extinct. 



Echidna sp. 



(PI. VIII. figs. 9-10). 



A number of bones of a large Echidna have been found, and 

 which in all probability belong to the described form Echidna 

 oiveni, Krefft. The specimens are, however, too fragmentary to 

 enable me to refer them definitely to this form. The remains 

 comprise the greater portion of the left ilium, with a fragment 

 of the sacrum attached, the lower portion of left femur, the 

 articular head of the femur, two vertebral centra, and a number 

 of fragments of long bones. 



The femur differs in one or two respects from E. acuJpMta. 

 The constriction of the shaft immediately above the condyles 

 is much less marked, and the shaft at this part is more flattened 

 than in the common existing species, while the depression above 

 the patellar surface is more marked and broader. 



The ilium is very considerably stouter proportionately than in 

 JC. aculeata. From the union by complete anchylosis of two 

 small fragments of the sacrum with the ilium it is evident that 

 the extinct species agrees with the living in the complete 

 anchylosis of the sacrum with the ilia.

Besides the above forms there are a few remains too fragmentary 

 for certain identification. Two fragmentary teeth probably repre- 

 sent Thylacoleo, while a detached molar belongs to a small species
