In addition to the interspecific differences concurred in by this testing of the 18 skull chracters, some intraspecific differences are observed in gervaisi. Part of this variation is shown to be sexual dimorphism, and the studied gervaisi material is sorted by it into three females and three males. Individual variation is evidently greater in the males. Comparison of external body measurements suggests that the length of the flipper of mirus generally exceeds that of gervaisi in proportion to total body length. Comparison of 31 skull measurements of the two species reveals nine measurements which, used collectiely, will separate skulls of these two species"--P. 23-24.
