- Same as Selachii.
Sorry, no etymologies found.
Of the viscera the liver in some animals becomes fatty, as, among fishes, is the case with the selachia, by the melting of whose livers an oil is manufactured.
In terrestrial viviparous sanguinea the gristle formations are unperforated, and there is no marrow in them as there is in bones; in the selachia, however — for, be it observed, they are gristle-spined — there is found in the case of the flat space in the region of the backbone, a gristle-like substance analogous to bone, and in this gristle-like substance there is a liquid resembling marrow.
Some men assure us that they have seen some of the selachia copulating hindways, dog and bitch.
