This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 Excerpt: ...species. Diagnosis.--Dentition apparently as in Tsaganomys, molars of similar apical pattern early lost, but less hypsodont and of much smaller size, the roots closing when full grown. Skull much narrower and smaller, the proportions more as in Bathyergus but the cranium not so flat and broad as in that genus; zygomatic arch of moderate proportions, the orbits not built out as in Tsaganomys, infraorbital foramen apparently small and low set, masseter attachment on under face of zygomata limited by a scar. The angle of the lower jaw springs from the side as in Tsaganomys, so far as the specimens show, but its exact relations are not so fully demonstrated. The permanent premolar is preceded by a minute, simple dp' and a large round molariform dp4, as in Tsaganomys.
