a Six specimens, from Jamaica. ^ Three specimens, from Jamaica. 



Specimens from Dominica and Guadeloupe are not quite so dark as those from 

 Jamaica, and may be different, but the series examined is much too small to settle 

 the question. I have not seen specimens from Porto Rico, St. Vincent, Martinique, 

 or British Guiana. Possibly the last are referable to the Costa Rican form.
