The crown dimensions of the dp4 and the M1 on the mandible in Tupaia glis were measured. The dp4 resembled the M1 in pattern, although they were by no means identical. The dp4 was approximately 60 to 85 % of Ml in size, and it was more compressed in the buccolingual than in the mesiodistal direction. The relative size of the talonid was larger for the dp4 than for the Ml. This result may be correlated with an occlusal function.
