Crex Bechstein, Orn. Taschenb., ii, 1803, 336. (Type, by monotypy, C. pratensis 

 Bechstein= Rallus crex Linnaeus.) 



Medium-sized Kallinae with bill much shorter than head, gonys 

 not more than one-fourth as long as culmen and strongly ascending 

 terminally; alula extending for only about half the length of long- 

 est primary coverts, and hallux (without claw) not more than two- 

 thirds as long as basal phalanx of inner toe. 



Bill much shorter than head, compressed, its depth of base equal 

 to nearly half the length of culmen, its width at same point equal to 

 about two-thirds the depth; culmen elevated basally slightly de- 

 pressed above nostrils, thence gently but decidedly decurved to tip; 

 gonys only about one-fourth as long as culmen, strongly ascending 

 terminally, its basal angle rather prominent, through slight but 

 distinct concavity of anterior portion of lower edge of mandibular 

 rami, the latter without lateral groove ; nasal fossa large and broad, 

 extending for more than half the distance from loral feathering to 

 tip of maxilla ; nostril small and narrow, acute anteriorly, obliquely 

 longitudinal but parallel with maxillary tomium, its anterior end 

 much nearer to laterofrontal antia than to tip of maxilla; latero- 

 frontal antia at upper edge of nasal fossa, where forming an obtuse 

 forward projection, thence sloping backward to the rictus; malar 

 antia forming a projecting obtuse angle, its apex about on vertical 

 line with that of laterofrontal antia; mental antia nearly on vertical 

 line with anterior end of nostril. Wing rather large, moderately
