The bones in the Tring Museum, which form the type of this species,
unfortunately have no history and their locality is unknown. It differs
from the other species of the genus by the slenderer proportions of the
tibio-tarsus, which is 22 inches long by 2.9 inches distal width, as
opposed to 24 inches by 4.2 in _elephantopus_ and 20 inches by 3.5 in
_ponderosus_, the two nearest in size. Femur: length 10.6 as opposed to
12.5 inches in _elephantopus_. {216}
