Tuere is little doubt in my mind that the characters of Linneus’ Ramphastos piscivorus were taken from an example of this species; it is true that the throat is described as white, which would militate against such an opipion ; but it is probable that the whiteness of the throat was due to the bird being out of health or to some other cause: if this supposition be correct, it will be said that the term peservorus ought to be the specific appellation adopted ; it is, however, so objectionable, being indicative of a habit not found to exist in any species of the family, that I have preferred employing Mr. Swainson’s name, carinatus, so peculiarly descriptive of the remarkable form of the bill. I do not know any species of the family which is subject
