Ex- tending backwards from the basihyal, between the cornua is a 'urohyal,' in reality a basibranchial. The pectoral girdle is well developed except in the flightless birds, and in some moas apparently it was entirely absent. The coracoids are large, the procoracoids rudimentary or absent. In most ratite forms the clavicles are absent; in all other birds they.
