GENUS GYMNOCREX Salvad. 



Distinguishable from all the other Rails occurring in Celebes by its having 

 the middle toe and claw much shorter than the tarsus, and by the large space 

 of bare skin behind the eye. Bill shorter than tarsus, high at the base, atten- 

 uated at the tip. Wing large, 4*'' and 5* primaries longest. Tail about as long 

 as the tarsus. 



The genus was described from Celebes. An aberrant species is known also 

 from the Halmahera group and the Papuan Islands.
