C(BR£BID^. 



This genus consists of two species peculiar to the Galapagos Archi- 

 pelago. Its true place is perhaps a little uncertain, but it seems to 

 como nearest to Conirostnim and Dacnls. From Conirostrum, 

 Gcrtliidea differs in having the wings and tail much shorter ; but 

 the form of the nostrils, the scntellation of the tarsi, and the propor- 

 tionate length of the toes are nearly alike in the two genera.
