Not illustrated. 1891 edition. Excerpt: ...subspecies we have the largest and heaviest skeleton of the Tamias striatus group. The skull, measured from the posterior border of the occipital condyle to the end of the nasals, averages 2 mm. longer than the largest specimens of lysteri before me. Though the skull of lysteri is relatively less in its parietal, interorbital and zygomatic breadth, the molar series of teeth are more widely separated than in griseus, and have a greater posterior convergence, the rows being more nearly parallel in griseus. The infra-orbital foramen is much larger in lysteri than in griseus. The heavier ossification of griseus is most apparent when the mandibles are compared. They are much larger and rougher for the muscular attachments, with strikingly larger condyles than in lysteri, from which it also differs in having the lower outline of the jaw much more concave, owing to the relatively greater development of the angular process, which is produced downwards and backwards. In general, the skull bears a closer resemblance to that of striatus than it does to lysteri, but differs notably from the former in its considerably larger size.
