| W. D. Matthew 1932 | -Sizemuch less than S. dolichops, about equal to Mionictis incerta or Brachypsalis matutinus, but agrees with Sthenictis and differs from the other two in the construction and proportions of the carnassial and premolars. The second third and fourth premolars are two-rooted, compressed, not crowded, p4 with well developed posterior accessory cusp. The shear of the carnassial is nearly anteroposterior, the metaconid well developed but not nearly as high as in Mionictis or Brachypsalis. The last molar has a single alveolus, which apparently contained a large anterior and smaller posterior root, closely connate. In S. dolichops the alveolus is round-oval apparently for a single root. |
