Range. — Coast of Gulf States, breeding from Grand Isle, La., west- 
ward, probably to northeastern Texas, southward in winter to Corpus 
Christi, Texas, and Tarpon Springs, Florida. 1 
In the appended table a comparison of the diagnostic charac- 
ters of all the forms of the restricted maritimus group in fresh 
plumage is given. As before remarked, abrasion so alters a 
breeding bird’s appearance that in some cases badly worn speci- 
mens are practically unidentifiable. Of the 17 breeding birds 
collected by Dr. Fisher on Grand Isle and by Mr. Mcllhenny on 
and near Averys Island, all but four are more or less suffused 
with pale ochraceous on the breast and flanks, the most diagnos- 
tic character presented by fisheri , and about half the series are 
still more or less distinctly streaked with black below. It is in 
unworn plumage, however, that the differential characters of 
these birds are most evident, and it is on specimens in this con- 
dition that the appended table comparing the four forms of the 
restricted maritimus group is based.
