Concerning the Tasmanian and Australian, it will be seen that these 
results confirm absolutely the conclusions previously drawn by Berry, 
Robertson, and Cross ; and it will also be subsequently found that, as regards 
the placing of the Australian on the minus side of the Tasmanian, these 
results confirm those about to be published by Berry and Robertson (28). 
The Gibraltar skull appears herein between Pithecanthropus erectus 
and the three Spy-Neanderthal crania. This lowly position may, however,

be due to the fact that I have only dealt with four measurements, inasmuch 
as it is well known that the Gibraltar calvaria is imperfect; or, on the 
other hand, it may be really due to the lowly position claimed for 
this skull by Keith and others. 
That the Galley Hill-Brux-Briinn group appear on the plus side 
of the Tasmanian-Australian series need cause no surprise, because they are 
herein dealt with as a group, and not singly as in Cross’s work. Even the 
latter observer placed one of them on the plus side and the other two on 
the immediate minus side of the Tasmanian.
