FAMILY TROCHILIDAE 285 



The type, in the American Museum of Natural History, taken 

 by J. H. Batty, with the wing 70.2 mm., while marked male, probably 

 is a female, from its small size, as is another Batty specimen with 

 the wing 73.4 mm., also marked male. 



The two pairs whose complete dimensions are given above are 

 birds that I collected personally. 



Resident. Found locally on Isla Coiba. 



I found this attractive bird only in the white mangroves (Lagun- 

 cularia racemosa) in the swamps where the Rio San Juan and the 

 Rio Catival enter Bahia Damas. They moved quietly among the 

 other hummingbirds that fed at the flowers in the tops of these trees, 

 so that only when they were seen clearly were they identified by their 

 larger size. They were not common.
