If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|Hibbard 1956||This species was first taken from the Rexroad formation at Locality
2, Meade County, Kansas. Later collecting at Localities 2 and 3
has furnished additional specimens, and these have been compared
with the holotype and the paratype of Bensonomys arizonae. It was
found that B. eliasi is a valid species. In both young adult and adult
specimens tbe lower incisor of B. eliasi has a greater transverse width than the lower incisor of B. arizonae. m1 in B. eliasi is more rectangular than the m1 of B. arizonae, which tends to be triangular , with the apex of the triangle at the anteroconid. The reëntrant valleys of m1. and m2 in B. eliasi are broader than those of B. arizonae. The holotype of Peromyscus eliasi (KUMVP 3941) is a fragmentary left lower jaw, with m1-m3, of a very old adult. The teeth are worn down to their bases, and only the outlines of a few of the reentrant angles and cusps remain.
