Discussion.—Specimens of P. lophiodon are common in Gashatan mammal faunas, and Russell and Zhai (1987) have previously reported P. lophiodon at Subeng. Although P. lophiodon is not abundant in our collection, we can confirm its presence at the Subeng site. Sulimski (1968) provided a comprehensive overview of the morphology of Pseudictops . Based on our specimens, we concur with his description and
