THERE appears to be no authority for the belief that, where the original description is unrecognizable, the name is applied on the basis of the first recognizable account which appears afterwards under the same name. If the work of subsequent authors is taken into account at all, that of Lacepede, Bonnaterre and Daudin must also be considered. They proposed the specific name caouana as a substitute for the Linnean caretta and in doing so might be considered to have fixed the Linnean name.
