We now come to various genera, whose species are peculiar for their strangely 

 shaped tails, the feathers of which are generally narrow and pointed. In the next 

 genus, Calothorax, the members of which are small in size, the outer rectrix is 

 shorter than the one next to it, and tlie four central rectriccs are almost hidden 

 beneath the upper tail coverts. The metallic hues are confined to the throat, and 

 are very brilliant.
