QUATERNARY FAUNA OF GIBRALTAR. 127 
In masses of ossiferous breccia sent by General Frome from Poco Roco, and in some 
forwarded, I am not sure from what point, by Captain Luard, I found, completely 
imbedded in hard breccia, remains of a large Boar, in such a mineral condition as to 
leave no doubt of their contemporaneity with the most ancient species. 
One of the specimens of this kind is a mass of breccia, which in a few cubic inches 
presents, much crushed, the greater part of the mandible, containing the canines and, 
taking the two sides together, most of the teeth, together with an apparently entire 
metatarsal and fragments of other bones. 
In another mass of the same breccia I found, and have partially chiselled out, a fragment 
of the upper jaw, which may or may not correspond with the mandible, and containing 
the last premolar and the first and part of the second molars. And from the same 
breccia I have also exhumed the distal extremities of the third and fourth metatarsals, 
cemented together in their natural position by the hard matrix, and together with these 
and but a little way apart from them the two corresponding phalanges, of which one is 
almost entire. ‘The conjoint width of the two metatarsals and of the proximal ends of 
the phalanges is 1""5. The phalanx measures 1-5 long. 
The specimens forwarded by Captain Luard consist of portions of the upper and 
lower jaws of the same individual (to judge from the accuracy with which the teeth 
fit), and containing each the three molars, all entire except the third lower: those 
that remain are most of them worn, and especially the upper first molar. The teeth 
measure :— in. 
m. 1 62 x 60 
m. 2 80°65 
nm. 3 . 1:30:70 
m. 1 60°40 
m. 2 80 x 50 
m. 3 x60 
The vertical diameter of the lower jaw opposite the first molar is 1'-6, and its 
thickness “95. The corresponding measurements in a specimen of an Italian Wild Boar 
in the College Museum are :— ;

So far as can be judged from such scanty materials, it would seem that a species of 
Sus having a dentition similar to that of the European Wild Boar existed on the
