PLAT'YPUS, n. A quadruped of New Holland, whose jaws are elongated into the shape of a duck's bill. The body is covered with thick hair and the feet are webbed.
This animal has been arranged with the Mammalia, but it is now presumed to be oviparous; at least its breasts have not hitherto been observed.
Two quadrupeds of New Holland, now called Ornithorrhynchus paradoxus and O. fuscus. They are monotrematous edentate mammals, the body covered with hair, a bill like a duck, teeth planted in a kind of gums, webbed feet with a venomous spur on the hinder leg, connected with a reservoir of poison in the soles of the feet, which is supplied by glands situated by the side of the spine, just above the pelvis.
