This includes two forms, of which one is to be separated as 
549). Ammodramus caudacutus subvirgatus Dwiauxr. 
Acadian Sharp-tailed Finch.’ 
“Similar in size and coloring to A. caudacutus, but paler and much less 
conspicuously streaked beneath with pale greenish gray instead of black or 
deep brown. Bill averages smaller. Compared with nelsoni, it is much paler 
and grayer, generally larger and with a longer bill.” Hab. “ Marshes of southern 
New Brunswick, Prince Edward Island, and probably Nova Scotia, and south- 
ward in migration along the Atlantic coast” to South Carolina. 
(62.) Page 413, A. maritimus: 
This includes four local forms, of which A. maritimus proper is restricted to 
the Atlantic coast (Massachusetts to northern Florida). The three which are 
to be separated are as follows: 
550a. Ammodramus maritimus peninsula ALLEN. 
Scott's Seaside Sparrow.’ 
Smaller and darker than A. maritimus, paler than A. nigrescens; back dis- 
tinctly striped with brownish black, chest and sides distinctly streaked with 
dusky and more or less strongly ashy. Hab. West coast of Florida (Cedar 
Keys, Tarpon Springs, etc.). 
5506. Ammodramus maritimus sennetti ALLEN. 
Texas Seaside Sparrow. 
Smaller and much paler than A. maritimus, with sides of hinder head (post- 
auricular region, etc.) distinctly buffy, also the chest; above conspicuously light- 
streaked; beneath narrowly but distinctly streaked across chest and along 
sides. Hab. Coast of Texas. 
—. Ammodramus maritimus macgillivrayi (Avp.). 
Louisiana Seaside Sparrow.‘ 
Similar to A. m. peninsule, but still darker, with dusky streaks on back 
broader and blacker, and margined externally (except along median line) with 
broad streaks of pale ash-gray or grayish white; pileum and hind-neck more 
strongly tinged with brown; post-auricular space and chest strongly tinged 
with buff (sometimes wholly deep buff), the latter distinctly streaked with black 
or grayish dusky. Hab. Coast of Louisiana; coast of Texas (Corpus Christi,
