splenial (and the gap separating them is but small) there would 
be no difference in the mode of their connection from that 
shown in the brain of the Babyrussa. There would be a similar 
appearance of the bifurcation of the splenial that has been 
yeterred to.

Brain of Babyrussa alfurus, dorsal view. ‘Three-quarters natural size.

Neither Mr. Garrod nor Dr, Elliot Smith mentions the interesting 
fact that the convolution lying between the splenial fissure and 
the corpus callosum (7. e. the hippocampal gyrus ?) appears on the 
surface of the brain and is—posteriorly at any rate—not much 
depressed below the level of adjoining regions of the brain in the 
Peceary, while it is completely concealed in the Babyrussa as in 
Sus, and apparently in Phacocherus. 'This arrangement is seen 
in other Ungulates besides Dicotyles. In Babyrussa the splenial 
gives rise to another fissure lying behind the oblique furrow 
which joins it with the superficially running coronal. This is
