200 SOME NOTES ON THE EARLY HOMINID^E 
of that species, until a specimen was procured. This mistake 
was quite pardonable on account of the poor light which filters 
through the tops of the thick foliaged trees. 
I myself have only seen these birds on one occasion ; they 
were feeding under the undergrowth, and their presence was 
detected on account of the rustling of the dead leaves on the 
ground as they scratched and hunted for seeds and snails, 
which food appears to be their chief diet. 
They were shy and most difficult to procure. 
Like F. I . schubotzi, these birds are much smaller than 
most of the other francolin, and possess very slender bills. 
So far as I am aware, neither eggs nor nestlings of these 
birds have been taken. 
It is to be hoped that further information regarding these 
two rare Forest Francolin will be sought for by members 
living near the Mabira Forest. 
SOME NOTES ON THE EARLY HOMINIDiE 
By E. Wynstone-Waters, F.R.S., Edinburgh. ( Late Senior 
Demonstrator of Anatomy at the Boyal College of Surgeons, 
Edinburgh.) 
The discovery in 1912 of the Piltdown fragments has 
supplied us with a fifth species of the Hominidse. Before 
touching on this interesting find, it will be well to review 
briefly the salient features of those portions which have been 
discovered of the other species. 
In the year 1865 Sir John Lubbock (the late Lord Avebury) 
introduced two terms, which have since been in very general 
use. He proposed that the Stone Age should be divided into 
two portions. The people of the later period he called Neolithic ; 
while, extending far behind this Neolithic stock, and living 
under very different climatic conditions, we have what he 
termed the Palaeolithic peoples — races of savages which roamed 
about during the glacial epoch, and were contemporary 
with such extinct forms as the Mammoth Elephant, Cave 
Bear, &c.
