1477- A portion of a condyle of a humerus or femur, of the proportions appa- 

 rently of those of a Mastodon ; it presents the same colour and heavy 

 mineralized and cracked condition as the fossils Nos. 1460 and 1461. 



From the alluvial or newer tertiary deposits in the hed of the Conda- 

 mine River, west of Moreton Bay, Australia. 



Presented by Lieut. -Col. Sir T. L. Mitchell, C.B. 



1478. A portion of one of the condyles of a femur, presenting nearly the pro- 

 portions of that of a Mastodon, and in the same heavy mineralized and 

 broken condition as the fossils Nos. 1460 and 1461. 



From the alluvial or newer tertiary deposits in the bed of the Conda- 

 mine River, west of Moreton Bay, Australia. 



Presented by Lieut. -Col. Sir T. L. Mitchell, C.B. 



1479. A fragment of the compact walls of the shaft, apparently from the inner 



border of a flattened femur : the length of the fragment is seven inches 

 and a half, and the thickness of the compact wall from one-half to two- 

 thirds of an inch. It corresponds in colour and mineralized condition with 

 the portions of the jaw of the Diprotodon australis, Nos. 1460 and 1461.

 mine River, west of Moreton Bay, Australia. 



Presented by Lieut. -Col. Sir T. L. Mitchell, C.B. 



1480. A fragment of apparently the head of a tibia of a quadruped, agreeing in 



size with the Diprotodon australis : the portion of articular surface here 

 preserved is gently concave at one part and convex at another, with a 

 deeper depression near the margin ; the greatest breadth of this surface 

 is five inches.

1481. A portion of the inner part of the proximal end of a right tibia of a 

 large mammalian animal : the part of the concave articular surface which 

 is preserved has a diameter of three inches and a half, but the traces of 

 the union of the epiphysis to the shaft are very plain ; the lower end of
