PRODIPODOMYS HI �� ARD, 1939

Prodipodomys mascallensis DOWNS, 1956

Holotype —From V4830 : left dentary with i1, p4 through m3, UCMP 39094 .

Referred specimens —From V 4833: partial maxilla with partial palate, left P4 and M1, UCMP 39895. From CIT 1869: p4 and m1, CIT 4002B.

Occurrence — V 4830, V 4833, CIT 1869.

Description —All material is described in Downs (1956). For UCMP 39094 and CIT 4002B the p4 has an X-pattern and 2 roots, the m1 and m2 are subequal with an H-pattern, and the m3 is small. UCMP 39895 is assigned here to this taxon, but may belong to Cupidinimus halli Wood, 1936 based on the following: the protocone on P4 is distinct and does not attach to the hypostyle lingually; however, it connects to the metacone-hypocone complex more lingually than other species in the genus.
