of the dorsal surface many shades deeper than Maryland ones, and the 

 under surface strongly rufous. The tail and wings, besides bein<>- much 

 darker, have the dark bars black, they being deep black on the tail, and 

 consequently far more conspicuous. The crissum, however, is lighter than 

 in the Maryland specimens, with the black bars broader. The Florida 

 specimens have also a much longer bill, they closely agreeing in every par- 

 ticular with the so-called Thryothorus Berlandieri of Northeastern Mexico 

 the Florida specimens even possessing the interrupted black bars on the 

 sides of the body said to occasionally characterize that species as distin- 

 guished from the T. ludovicianus. The differences between Florida and 

 Maryland specimens of T. ludovicianus in the length of the bilL as well 

 as in color, are very striking. They are paralleled, however, in Harpo- 

 rhynchus rufus and in other species. The T. Berlandieri hence appears to 

 be only the smaller, darker form of T. ludovicianus, — the Mexican homo- 

 logue of the Florida representatives of this species. 



The Thryothorus Bewickii, from what is known of its range, doubt- 

 less occurs as a resident bird in Florida, but is probably rare there, as 

 it generally is elsewhere. 



lS.t Anorthoura hy emails Rennie. Winter Wren. 

 Rare. — Board/nan. 



19-t Cistothorus stellaris Cabanis. Short-billed Marsh Wren. 



Rare. Enterprise, February. — Boardman. 



The Telmatodytes palustris doubtless also occurs as a winter resident. 



MOTACILLID^I. 



20.t Anthus ludovicianus Lichtenstein. Titlark. 

 Common. Several were usually seen in company, but along the 

 river I saw no large flocks. According to Mr. Maynard, however, they 

 occurred in large flocks in the " old fields " away from the river. 



SYLVICOLID^J. 



21. t Mniotilta varia Vieillot. Black and White Creeper. 

 Not uncommon throughout the winter, but much more numerous in 

 March. 

 22.t Parula americana Bonaparte. Blue Yellow-backed Warbler. 



Occasional during the winter months, but very numerous after the 

 1st of March, soon after which time they were in full song.
