xlvii, pp. 571-574, pi. xxi. 
After reviewing Owen’s writings upon the extinct Kangaroos, for 
which he established the genus Procoptodon , the author describes two 
mandibular rami from the clay beds in the neighbourhood of Bingera, 
N.S.W., which belong to this genus, and from their characters and a com- 
parison of them with the lower jaws in the British Museum, he maintained 
that they indicate two distinct species of the genus, for which he retained 
the names P. rapha , Ow., and P. goliah , Ow., though it is possible that 
the types of those two species are Really specifically identical, in which 
case the name P. pusio , Ow., might have to be adopted for one of the 
species described.

the transitory existence of a similar organ in the young of some other

Leciie, W. Beitrage sur Auatomie des Myrmecobius fasciatus. Biol. 
Foren. iii, pp. 136-154. 
The author confirms the relationship of Myrmecobius to the Dasy- 
urid,ce , although in some respects it is more specialized than the other 
members of the family. By its dentition it is, however, closely connected 
with Mesozoic forms.
