The specific name was given on account of the extraordinary swiftness of the animal.
He was distinguished for his beauty, swiftness of foot, and skill as a charioteer; though the youngest among the Greek princes, he commanded the Pylians in the war, and performed many deeds of valour.
He did so with masterly skill and swiftness, and the triumphs of Ulm and Austerlitz hid from view the disaster of Trafalgar; and the only official reference to that crushing defeat was couched in these terms: "Storms caused us to lose some ships of the line after a fight imprudently engaged" (speech to the Legislature, 2nd of March 1806).
The swiftness, the strength and the highly developed power of scent in the dog, have made it a powerful ally of man against the other animals; and perhaps these qualities in the dog were necessary to the establishment of society.
In strong contrast to the ungainly toucan is the tiny humming-bird, whose beautiful plumage, swiftness of flight and power of wing are sources of constant wonder and admiration.
