Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
The kingdom of Numidia stretched from the river Molochath to
the great Syrtis,(9) bordering on the one side with the Mauretanian
kingdom of Tingis (the modern Morocco) and on the other with Cyrene
and Egypt, and surrounding on the west, south, and east the narrow
district of coast which formed the Roman province of Africa.
In addition to the old possessions of the Numidian chiefs, it embraced
by far the greatest portion of the territory which Carthage had possessed
in Africa during the times of its prosperity--including several
important Old-Phoenician cities, such as Hippo Regius (Bona) and Great
Leptis (Lebidah)--altogether the largest and best part of the rich
seaboard of northern Africa. Numidia was beyond question, next to
Egypt, the most considerable of all the Roman client-states.
