be that the species is quite distinct from [[underlined]] D. leucas [[/underlined]]. For example, the vertebral formula of [[underlined]] D. vermontana [[/underlined]] as given by Thompson is C.7, D. 13, L 12. Ca 20 = 52. The normal formula of D. leucas is C. 7, D. 11, L. 9, Ca. 23 = 50. Although all species of dolphins vary much in [[strikethrough]] their [[/strikethrough]] their formulae, there is [[strikethrough]] no prob [[/strikethrough]] such amount of variation as is shown in the his formulae cited. If it [[strikethrough]] will correct [[/strikethrough]] [[insertion]] ^ the difference notes actually existed [[/insertion]], there would be a strong probability that D. vermont was distinct. As a matter of fact, however, Thompson did not have all the vertebrae and he may or may not have been mistaken in calculating the number lost. I should want to see the specimen before forming an opinion on that point.

J. W. Dawson in Amer. Sci. 1883, p. 201, states that the Cornwall, Ontario, [[strikethrough]] specimen [[/strikethrough]] fossil specimen was compared with recent bones of D. leucas in McGill Coll. Mus., by E. Billings, and that the latter concluded that it belonged to the modern species. Dawson adds "I
