Fig. 4. Eight femur. 



Fig. 5. Eight fibula. 



Fig. G. Eight tibia. 



Fig. 7. The innominate bones of the female Thylacine — inferior aspect. 



(a) The cartilaginous nodules, which represent the marsupial bones. They are 



apparently a direct continuation upwards of the cartilage which intervenes 

 between the ossa innominata at the symphisis pubis. 



(b) Ligament connecting the marsupial cartilage with the pectineal eminence. 



In concluding this Eeport the author feels under heavy obbgations to the gentlemen 

 who have so faithfully delineated the various objects in the accompanying plates. More 

 especially is he indebted in this respect to J. Dunlop Dunlop, M.B. (now in Adelaide, 

 Australia), who has contributed eight plates, and to Arthur Thomson, M.B., Senior 

 Demonstrator of Anatomy in the University of Edinburgh, who has executed two plates, 

 and at the same time superintended the drawing of the Plates XII. and XIII. by Mr. T. 

 Lauder Sawers. As already stated, the plate representing the feet of the Koala and the 

 Virginian Opossum is the work of Alfred H. Young, F.E.C.S., of Manchester, and was 

 drawn from his own dissections.
