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. JI have not seen specimens from Porto Rico, St. Vincent, Martinique, 
or British Guiana. Possibly the last are referable to the Costa Rican form.
