AFFINITIES AND HABITS OF THYLACOLEO. 



Thylacoleo would be a group of probably small insectivorous 

 forms. 



In the subjoined scheme an endeavour is made to illustrate the 

 probable phylogenetic relationships of the Diprotodont Marsupials. 

 The exact positions of Phascolarctus and Phascoloini/s are left as 

 doul}tful, and Ccenolestes has been omitted, as I consider the 

 evidence which would place it with the Australian Diprotodonts 

 not sufficiently strong, and in any case it is evidently not a near 

 ally of any of the Australian forms. 



I am much indebted to my father, Mr. John Broom, for his 

 assistance in copying for me papers which I could not otherwise 

 at present have had an opportunity of seeing.
