Family RALLIDAE

Family RALLIDAE.

In this family the sternum closely resembles that of Turnix and has a similar deep notch on each side. There is a small aftershaft to the contour feathers and the fifth secondary is absent. The Pterylosis shows long lateral bare tracts on the neck. The deep flexor tendons are Galline, i. e. the flexor longus hallucis supplies the hallux and the flexor perforans digitorum the three other toes, the two tendons being connected by a tendon passing from the first to the second.

The family contains the Rails, Crakes and Coots and these are represented by various species practically throughout the world.
