Sydney Anderson Records of Harvest Mice, Reithrodontomys…

The subspecies anthonyi has been known previously by seven specimens, none of which is fully adult, judging from Hooper's (1952:134) comment that the adult pelage of anthonyi is unknown. Six of our seven specimens are clearly adults as is shown by well-worn teeth and degree of development of temporal ridges. The seventh is a young animal in process of postjuvenal molt.

Individuals from our series in general resemble specimens of Reithrodontomys mexicanus orinus from the vicinity of Guatemala City but differ from the latter as follows: dorsal pelage brighter (with less suffusion of black) , "peppered" in appearance, shorter and sparser; ears distinctly paler, owing both to the paler color of the skin and the paleness of the hairs inside the pinna; dark tarsal stripe not extending onto hind foot; ears and hind feet uniformly smaller

One female (KU 65400) contained two embryos that measured 18 mm. in crown-rump length.
Average and extreme external and cranial measurements of the six adults are: total length, 183.6 (170-198) ; length of tail, 106.0 (95-113) ; length of hind foot, 18.0 (18) ; length of ear from notch, 14.0 (14) ; total length of skull, 22.21 (21.4-22.8)
