In size there is very little difference between St. Vincent and Domin- 

 ica specimens. This is probably a fairly well-marked insular form, 

 depending upon its darker coloration for recognition. 



Mr. A. H. Veri'ill, in his description of this form, gives the irides 

 as "white or pale straw at all ages and in both sexes," and describes 

 the eggs as "dull white, heavily washed and blotched with rufous, 

 umber and grayish brown." If the measurements given by him 

 are correct (1.80 by 1.50 to 1.85 by 1.55), the eggs seem to average 

 smaller than eggs from the eastern United States.
