- The cotylae are also features on the proximal end of the radius and of the ulna in birds.
In classical antiquity, the cotyla or cotyle (Gr κοτύλη) was a measure of capacity among the Romans and Greeks: by the former it was also called hemina; by the latter, τρυβλίον and ἡμίνα or ἡμίμνα. It was the half of the sextarius or ξέστης, and contained six cyathi, or nearly half a pint English.
