Axrnoucn the evidence of the very slight degree of 
inflection of the angular process in the lower jaw of the 
Amphitherium Prevostii, (fig. 15,) turns the scale in favour 
of its affinities to the placental Insectivora, yet the range 
of variety, to which the character of the inflected angle of 
the jaw is subject in the different existing genera of 
Marsupialia, warns us against laying undue stress upon its 
feeble development in the extinct genus of the Oolitic epoch, 
and incites us to look with redoubled interest at whatever 
other indications of a Marsupial character may be present 
in the fossil remains of other genera and species of Mam- 
malia that have been detected in the Stonesfield slate. 
In that remarkably perfect and interesting specimen, 
presented to the British Museum by Mr. Broderip, its
