1. The pyriform lobe is connected by association fibres to the 
nucleus amygdale, corpus striatum, and pallium of its 
own side, and with the pyriform of the opposite hemi- 
sphere by the anterior commissure. 
u. The tuberculum olfactorium is intimately connected with 
the corpus striatum, and with the pallium by means of 
a large fibre bundle—the probable homologue of the 
anterior segment of the cingulum (Beevor, 2). It is also 
connected with the hippocampus by the Riechbundel of 
Zuckerkandl (fig. 10, £.). 
b. The internal olfactory radiation (fig. 11, 2.0.7.) arising in 
the olfactory bulb and terminating mainly in the precom- 
missural area, but partly also in the hippocampus (36), 
and probably in the tuberculum olfactorium. 
c. The peduncular projection bundle extends from the olfactory 
lobe backwards through the floor of the thalamencephalon 
to enter the pes pedunculi mainly. Some fibres probably 
terminate in the mammillary region (figs. 4 and 11, p.p.0.). 
d. The pars olfactoria (fig. 11, p.o.). 
e. The olfactory bundle of Zuckerkandl (fig. 10, £.). 
1. A series of fibres arising in the precommissural area 
and tuberculum olfactorium, proceeding backwards in 
the fornix to terminate in the hippocampus. 
u. A series of fibres arising from the pyramidal cells of the 
hippocampus, and after passing through fornix and 
septum, terminating in the base of the cerebrum in the 
region of the nucleus amygdale (fig. 10, B.). 
It is to be hoped that before long better material will be avail- 
able with which to supplement these imperfect notes upon the 
nervous system of this interesting Mammal. For, quite apart 
from the deep interest attaching to the anatomy of this aberrant 
and peculiar Marsupial, the brain of Votoryctes presents to the 
comparative neurologist quite a number of instructive features 
of the deepest interest and highest importance.
