Ammodramus maritimus peninsulae Allen. 
This race was described by Dr. J. A. Allen from specimens col- 
lected by W. E. D. Scott at Tarpon Springs, on the west coast of 
Florida, in February, 1888. 1 With the Florida birds Dr. Allen 
identified a series of ten adult and six immature birds collected 
by Dr. A. K. Fisher at Grand Isle, Louisiana, in June, 1886. 
Shortly afterward Dr. Allen recorded a specimen of peninsula, 
in the collection of G. S. Miller, Jr., which had been collected on 
Sapelo Island, off the coast of Georgia, Dec. 14, 1887. 2 Mr. 
Brewster also referred to peninsula two specimens taken on this 
same island in December, 1887, and Dr. Allen identified with the 
same form a specimen from near Charleston, S. C. 3 
Mr. W. E. D. Scott records peninsula as a very common winter 
resident near Tarpon Springs, 4 the type locality, where, however, 
it does not breed. In fact the breeding grounds of this Sparrow 
on the Gulf coast appear to be as yet unknown. Mr. C. J. 
Maynard J states that he found Seaside Sparrows, doubtless this 
form, about to breed at Cedar Keys, Florida, in February. The 
date is surprisingly early but it is quite probable that peninsula 
may breed in the marshes at Cedar Keys. 
Ammodramus maritimus macgillivraii Ridgw. (not of 
Audubon) . 
March 25, 1891, I collected at Corpus Christi, Texas, two 
specimens of a dark Seaside Sparrow which were provisionally 
referred to peninsula, with the statement that they were darker 
than that form and had gray instead of olivaceous edgings to the 
feathers. 8 They were evidently winter visitants and their breed- 
ing ground remained unknown until Mr. E. A. Mcllhenny col- 
lected a large series of breeding birds on and near Avery’s Island,
