Islands of the Coast of Yucatan, ^c. 363 



Cozumel I. ; Ruatan I. 



Apparently common on botli these islands. We likewise 

 observed it on some of the coral islands off the coast of British 

 Honduras and at Yzabal on the mainland in September. It 

 is also common in Northern Yucatan in April and May. In 

 the interior of Guatemala this Tyrant seldom occurs^ but we 

 have an example from Retalhuleu, on the coast-lands border- 

 ing the Pacific. Its southern range extends to Ecuador, 

 Peru, Bolivia, and the Amazons valley.
