Sometimes it has a shade of pinkâsometimes of orange or yellowish. The close resem- 4 3 Fk;. 30. riethoihiii eliiciriis cr/ilhronolKg, 4(<2c. ^ti St. CaUiariius. Canada; ;. blance in size and character with the l're(iuent association in the same localities between the two species have given rise to the belief that tlu'y were ditJereut sexes of the same species. That this supposition is in- correct is i)roved by the fact that both males and females are found of each kiiul, as was long ago noticed by llaldeman. As varieties they are very permanent ones, as I have Ibund all the young of the same brootl or set of eggs, whether in the eggs or Just escaped from them, uniforndy with either dark backs or red ones. 1 have found adult red- backed specimens watching eggs with red-backed endiryos, and biowii backed in charge of brown-backed embryos. Tliere is also some dillci- euce in geographical distribution. Thus, on the west side of Laki; Champlain,in Essex County, New York', I'rol'essor Jiaird states that lu^ lias found the red-backed salamaiuler very common, and never saw there the r. cinercus.
