* The typical characters alone are given of what I consider to be the 
primary groups; but as the circular succession of the subgenera in each is 
a subject which’ requires more investigation than I have yet been able to 
give it, I shall not attempt to impose names upon the minor groups, whi ch 
cannot as yet be properly demonstrated. > 
\ ¢ The rank of this group is very uncertain. I am inclined to think that 
the Trochilus recurvirostris is the type of the grallatorial divising oI this 
family ; but this is mere conjecture. ; j
