Carriker : List of the Birds of Costa Rica. 619 



the chin, malar, suborbital and auricular regions is exactly the same, 

 while the blacker tail of the Costa Rican bird as given by Mr. Ridg- 

 way is in some cases reversed. As for the measurements, the follow- 

 ing list will show that they are so variable in birds from the same 

 region, that they are of no value whatever.

The Costa Rican range of this species covers the Caribbean slope 

 from about 1,000 up to 4,000 feet, but it is a very rare bird, few 

 specimens having ever been taken. It inhabits the dense, humid 

 jungle of the above mentioned region and is quite similar in its habits 

 to M. Icemosticta.
