" Wood Rats were abundant over the entire country visited from the summits of the Huachuca, Graham and Chiricahua Mountains to the lower desert regions. About Fort Lowell they were exceedingly abundant, having numerous nests among (actus beds, brush fences, and in willows along the Rillito.

The last lower molar on each side has an extra enamel loop on the inner side, as though an attempt were made to reproduce the middle loop, normally developed in M1 and M^. A slight supernumerary cusp is also seen on the outer side of MT and .\L5 of both rami, and two on the outer side of M^. They are all merely incipient points arising from the cingulum, but are not without morphologic interest. (See Fig. 12.)
