The vertebral formula and scapular ratio of Mogera tokudae from Sado Island in Japan were studied. The vertebral formula indicates the number of cervical, thoracic, lumbar, sacral and caudual vertebrae. The formula of this species is 7・13・6・6・13 and is distinctly different from that of 7・14・5・6・12 seen in Mogera wogura, M. minor and M. kobeae, and very similar to 7・13・6・5・13 of euroscaptor mizura mizura and Euroscaptor mizura ohtai, except for the difference in the number of elementary vertebrae constituting the sacrum. The mean value of scapular ratio, that is the percent of the length of scapula to the length of skull is 68.7% in Mogera tokudae. This ratio is much lower than those of 73.4 and 73.7% of M. wogura and M. kobeae respectively, and much higher than those of 63.7 and 63.21% of Euroscaptor m. mizura and E. m. ohtai, but not different from Mogera minor which is 69.5%. As indicated by the vertebral formula, Mogera tokudae may be more closely related to Euroscaptor mizura than to Mogera wogura, M. minor and M. kobeae.
