Taxidea taxus (F:AM 30786) A. lateral and B. ventral views of skull; C. occlusal view of upper dentition; D. lateral view of mandible; E. occlusal view of lower dentition. Scale 1/1. iMc' Taxidea material. Preliminary studies indicate that all of the material is referable to Taxidea taxiis, but subspecific designation of the Blancan and late Rancho- labrean material seems warranted. A trend in the evolution of Taxidea during the Pleistocene is a gradual increase in size culminating in the huge Rancholabrean forms; there was a slight decrease in size during postglacial times, and this was fol- lowed by a slight increase in size in Recent times. The largest extant badgers are found in the northern parts of their range. All of the measurements taken on the Alaskan material, except the length of M^ which is quite variable, exceed those in my postglacial and Recent sample. Pronounced size differences are noticed in zygomatic breadth, mastoid breadth, and length of mandible (see Table 6). The well preserved skull, ace. no. 552, belonged to an adult animal. The low broad skull is characterized by strong zygo- matic arches, well developed sagittal and lambdoidal crests, a wide occiput with highly inflated tympanic bullae, and sepa-.
