 stout ; the upper man-

 rounded at the base ; the 

 lower carinated, recurved, 

 its margins covered by 

 those of the upper. 



Nostrils basal, covered by

Interior fore toe small. 



The species of this genus are chiefly confined to 

 the southern hemisphere of the old world. I have 

 followed Mr. Swainson in giving the English name 

 Crab-eater to them, as the typical species is known 

 to subsist on those animals.
