Beak cleft towards the eye, 

 its sides compressed ; the 

 upper mandible slightly 

 sulcated, towards the tip 

 bent down ; the lower be- 

 neath angulated. 



Nostrils placed in the middle 

 of the beak. 



Feet four-toed, the outer toes 

 connected by a membrane 

 at the base. 



There is but one species belonging to this genus, 

 which is distinguished by its peculiar beak : this 

 part is rather stout at the base, and nearly straight, 

 but inclines downward toward the tip : on the 

 upper mandible is a long furrow, two-thirds of the 

 length of the beak, in which the nostrils are placed ; 

 these appear to be only a slit. The manners of 

 the species are unknown.
