The crown dimensions of the mandibular molars in
Tupaia glis were measured. All the mean values of crown diameters and areas were larger for the M
1 molar than for the M
2 and M
3. The last two molars were more reduced in the talonid component than in the trigonid compared to the M
1, and were more reduced in the buccolingual than in the mesiodistal direction. The most common molar size sequence (MSS) was M
1>M
2>M
3, and this pattern was more frequently observed in the talonid component than in the trigonid. In the canonical discriminant analysis, all the cases of the M
3 were discriminated correctly, but some cases of the first two molars were confused with each other. The molars size of the mandible was closely related to that of the maxilla.
