SUB-FOSSIL REMAINS FROM KING ISLAND. 
number between 240 and 250. Weare probably correct in regard- 
ing the length of an average mature tarso-metatarsus as being 
between 230 and 240 mm.

In the following table are given the measurements of the femur, 
tibio-tarsus, and tarso-metatarsus of seven mature specimens of 
Dromeus nove-hollandia, from which it will be seen that there 
is considerable variation in the size of the bones of the mainland 
form, though not so great as in the case of the island species :—

In the following table we give side by side the lengths of the 
same bones in the three species, taking, in the case of D. minor 
and D. nove-hollandiew, hones that belong to fair, average-sized, 
mature specimens.

There is a most striking difference in size between the pelvis 
of the mainland and that of the King Island bird, and fortunately, 
though the bones are very fragile, only one specimen retaining 
any appreciable part of the pubis and ischium, sufficient measure- 
ments can be obtained to warrant the separation of the two 
species on the evidence of this bone alone.
