Diagnosis
ReferenceDiagnosis
W. D. Matthew and W. Granger 1923Cheek teeth 3/3, the upper series decreasing in length and width from first to third, the lower series subequal and of nearly square outline. Brachyodont crowns, the cusps arranged in pairs, two pair each on Mm2 and Mm3, but a well-developed anterior pair on M1 and a rudimentary heel on m1. In the lower teeth the outer cusps tend to be crecentic, the inner are nearly round; the upper teeth reverse this arrangement. The skull is cricetoid in proportions, rather long and narrow, arches well preserved on the type and several other specimens show that the infraorbital foramen was round and of rather large size, resembling some of the dormice, e.g. Graphiurus, also Pseudosciurus and other Oligocene genera and, to a less extent, the Dipodidae, the masseteric scar on the zygoma wholly beneath it and defined by a clear-cut margin.
