of Dinotherium from the rest of the Proboscidean stock most 
likely took place in Africa, where the intermediate links may 
therefore be expected to be found. Dr. Felix Oswald has 
recently collected further material from Karungu, which seems 
to prove the correctness of the view put forward in the original 
paper on Dinotherium hobleyi that the beds in which it occurs 
are of Lower Miocene age. Similar faunas have been found 
at that horizon in Europe, India and elsewhere, and no doubt 
remains of Tetrabelodon and other characteristic forms will 
eventually be discovered in British East Africa. It should be 
noted that remains of a larger species of Dinotherium have 
already been collected by a French expedition from beds, 
probably of Pliocene age, on the river Omo to the north of 
Lake Rudolf. 
The figure shows the type specimen of Dinotherium hobleyi 
together with the restored outline of the whole jaw ; the down- 
turned tusks and the simple two -ridged molars are well shown : 
it is uncertain whether there were large tusks in the upper jaw 
or not. 
The finding of this specimen shows what great possibilities 
of the discovery of completely new forms of extinct animals 
are afforded by British East Africa. An expedition to German 
East Africa has already found remains of a gigantic Dinosaur, 
some of the bones of which are about twice the size of those of 
the well-known Diylodocus carnegii, a reptile which was about 
eighty feet long. Now this discovery of a new mammalian 
fauna of Miocene age gives great hopes that in the near future 
important additions to our knowledge of this region may be 
made. It is greatly to be desired that anyone finding teeth 
or bones (or even fragments of them) that appear to be in a 
fossil condition, should send them to the British Museum for 
determination ; for even though the specimens themselves may 
not be very good, they may be sufficient to determine whether 
further collecting on the spot would be likely to lead to valuable 
results.
