himself justified in concluding that the Diprotodon combined the 
characters of Phascolomys with those of Macropus, exhibiting 
both upon a gigantic scale, and constituting one of those links 
in the chain of being which the course of time lias broken and 
destroyed. Prof. Owen also stated that a large collection of 
bones of the Dinornis had been obtained from a new locality by 
Mr. Percy Earle. This collection contains four of the species of 
Dinornis already described, including the three most remarkable 
for gigantic stature. One of these, with a stature nearly equalling 
the ostrich, presents in all the bones of its leg double the thick¬ 
ness in proportion to their length, and must have been the strongest 
and most robust bird in proportion to its size that ever existed. 
Of the gigantic species, vertebrae, ribs 7 and an almost entire 
sternum, most resembling that of the Apteryx, have been 
obtained. The Rev. Mr. Williams has also transmitted the 
cranial portion of a skull related in size to the Dinornis struthoides , 
manifesting many peculiarities and a striking resemblance to the 
same part in the Dodo and Apteryx. 
SILURIAN FOSSILS FROM HOBART TOWN. 
(From the Quarterly Journal of the Geological Society, August 1845.) * 
The following are the results of the examination by M. de 
Verneuil of certain fossils collected from Mount Wellington, near 
Hobart's Town, New South Wale*. The schistose sands and 
carboniferous limestones appearing among compact diorite in 
different points near Hobart's Town are often flattened by the 
enormous pressure they have undergone, and the shell is often 
gone and only represented by an imperfect cast. 
Produclus puslulosus (Phillips.) A species closely resembling 
P. scabriculus (Sow.), and identical with the species common in 
the mountain limestone of Yorkshire. 
Spirifer very near S, trigonalis . It is extremely abundant in 
the collection, and attained a large size. It has five or six ribs on 
each side of the dorsal furrow.
