Century Dictionary and Cyclopedia
dentirostralHaving the characters assigned to the Cuvierian Dentirostres. The notch, nick, or tooth of the bill of the Dentirostres is not to be confounded with the tooth of the bill of certain birds of prey, as falcons, nor with the series of teeth of the lamellirostral birds, as ducks. In very many technically dentirostral birds there is no trace whatever of a notch or tooth.
