Sir liichard Owen has since described the remains of an Echtdna from the 
Wellington Valley Caves as E. Bamsayi, but he made no comparison between his own 
and Mr. KrefEt’s fossils. It is, however, probable that Mr. Richard Lydekker is correc 
in uniting both in one species. He remarks-“ Considerably exceeding in size the exist- 
ing E. Bruijnii of New Guinea.” Sir Richard Owen’s type was obtained in the

Ohs. The existence of the Platypus in Post-Tertiary times in Queensland is 
believed by Mr. De Vis to be assured from the presence of an adult right tibia, 
shows no sign of having been inherited from a less modified, that is, more reptilian 
precursor ; on the contrary, it possesses all the character of the genus as represented y

nerhans worthy of remark that, presuming this tibia to be full-sized as well as adult, 
Fndicates a species of smaller dimensions than the present one.” The bone is even thoug 
to represent a distinct and undescribed genus.
