The present species differs decidedly from Hirundo euchrysea from Jamaica, that species having that upper parts bright golden-green, and lacking the blue on the forehead entirely. The Santo Domingo bird is also larger, and the bill is apparently somewhat more slender.
Dr. Bryant mentions the present bird in his list as "H. euchrysea (var. dominicensis?)," stating that on account of its smaller bill it might be a variety, but he gives no description by which it can be identified.
I have named this species in compliment to P. L. Sclater, Esq., of London, England.
