88 Scott, Supplementary Notes o?i Florida Birds. [April 



Cistothorus marianae, sp. nov. Marian's Marsh Wren. 



To an apparently undescribed species of Marsh Wren, lately discov- 

 ered in the salt water marshes at the mouth of the Anclote River, Hills- 

 boro County, Florida, I propose to give the above name, after my wife, 

 Marian J. Scott. 



Before me is a series of fourteen birds on which the species is based. 

 No. 4595, $ ad.. Tarpon Springs, Fla., 6th January, i8S8, and No. 4594, 

 5 ad.. Tarpon Springs, Fla., 5th January, 188S, being selected as the 

 types of the species.* 



Above olive brown, having in rare cases a slightly rufous tinge. The 

 black area of the back much as in C. palustris, but not so clearly defined, 

 and the white streaks in this area not so numerous or pronounced. Rump 

 and upper tail-coverts with narroixj transverse bars of black, or darker 

 olive brown. The olive of the upper parts usually showing on the top of 

 the head, as a median line, which is sometimes a quarter of an inch wide. 

 On each side of this, dai-ker brown or black, like the patch on the back. 

 A superciliary stripe of white and dark brown feathers. Area in front of 

 eye dark. Below white on belly and throat; flanks and sides olive, lighter 

 than that above, and barred with darker olive or brown. The coloration 

 of the flanks and sides usually spreads over the breast, which in man}- cases 

 is dotted with small triangular black blotches. Lower tail-coverts ashy 

 or dirty white, barred broadly and conspicuously with black or deep olive 

 brown. Tail dark with lighter barring of deep ash, the bars being rarely 

 continuous. Wings dark olive brown with darker markings. Average 

 measurements of males: Length, 4.85; wing, i.So; tail, 1.70; exposed 

 culmen, .50. The average measurements of the females are appreciably 

 less. 



Iris hazel brown ; bill above dark seal brown, the lower mandible being 

 lighter at and near its base. 



The great difterence between this species a.nd pa I ustr is is in the conspicu- 

 ous barring of the upper and under tail-coverts and the feathers of the 

 flanks, and olive instead of rufous brown coloring throughout, with the 

 much darker coloration of underparts. I may state that with this series of 

 birds I have taken three palustris, which are entirely similar to those of 

 the northern marshes. 



The new bird is quite common on all the salt marshes of this immediate 

 vicinity (Tarpon Springs'), and probably all along the west coast of Flor- 

 ida as far north as Cedar Keys, where it is known to occur. It is probably 

 resident and breeds, though of this I have as yet no positive knowledge. 



The extent of the dark color on the underparts varies considerably, and 

 I have two individuals that show scarcely a trace of Avhitish beneath, 

 either on throat or belly.
