Remarks.—While the total length of the bill in the Coiba Island 
birds is only slightly greater than in mainland individuals, breadth 
and general bulk are appreciably more. The generally darker color 
of the new race is in line with the general tendency of the resident 
races on Coiba. 
The subspecific name actuosus, lively, active, has been chosen to 
indicate the sprightly actions of these attractive birds.

There appear to be few of these grackles present, and those few 
during January ranged only in the southern section of the Bahia 
Damas. We saw the species first on January 18 in the outer man- 
groves at the mouth of Rio Catival, when we encountered a pair and 
secured the female. Two days later we shot a male at this same point, 
presumably the one seen on the first occasion. The guards stationed 
at the Maria work camp told me that there was a morning and 
evening flight of a few small flocks from a roost somewhere near 
Playa Blanca to feeding grounds around the swamps at the mouth 
of the Rio San Juan.
