[Nov. 20 ou plutot guillochee " surface of the teeth, under the name of D. rostratus, Cuvier, by Desmarest in the ' Nouveau Dictionnaire d'Histoire Naturelle,' t. ix. p. 160 (1817), and the ' Mammalogie,' p. 515 (1822) ; and they appear under the same name in the second edition of Cuvier's ' Regne Animal,' vol. i. p. 289 (1829). In the fourth (posthumous, 8vo) edition of the ' Os3emens Fossiles ' (1836) the skulls figure under the name of rostratus, the editor, Fred. Cuvier, saying, " Nous substitutons au mot frontatus du tcxte du quarto, celui de rostratus qui est le nom veritable de cette espece, comme mon frere Va reconnu." In F. Cuvier's ' Histoire Naturelle des Cetaces,' of the same date, these skulls are associated with Van Breda's figure of the external form, with the remark that " le nom, de rostratus est sans doute celui que ce dauphin conservera dans les catalogues metho-diques" (p. 158). Notwithstanding the very definite character of these statements, and also Desmarest's determination in 1817, the name frontatus as applied to this species has lingered on, as will be seen by the synonymy below, probably in consequence of identifications made with the earlier editions of the 'Ossemens Fossiles,' without regard to the later rectification. The objection that might possibly be raised that this species is not the D. rostratus of Shaw, as Cuvier at first thought it might be, is unimportant, as no confusion can arise with that animal, which (if recognizable at all) belongs to a totally different genus, and is now universally known by the specific name of gangeticus applied to it by Lebeck, and which is simultaneous with, if not prior to, Shaw's name. The synonymy will therefore stand as follows :- 1 Delphinus rostratus (Shaw), Cuvier, Ann. du Museum, xix. p. 10 (1812). Delphinus rostratus (Cuvier), Desmarest, Nouv^ Diet. d'Hist.
