The American species of this genus present many slight modi- 

 fications in the proportions of the tarsus and toes, the elevation of 

 the culmen of the bill, the length of the tail and tail-coverts, and the 

 denudation of the lower part of the tibiae. It appears to us impos- 

 sible to establish satisfactory generic divisions upon these characters, 

 at any rate without a careful examination of the Old- World species 

 of the group. It is even difficult to group the American species in 

 minor sections ; but the following may serve as a temporary arrange- 

 ment of the subgenera :— 



a. majores : tarsus et digiti elongati. 



a', dorso maculato 1. Porsana. 



b'. dorso immaculato.
