CATALOGUE OF VERTEBRATES. 661 



"Migratory. Abundant. Arrives in April and remains till 

 October. They live along streams of water or about marshes, 

 but spend much of their time in the trees. They are seldom 

 seen on open ground. Strictly inoffensive. Is the most abun- 

 dant of the three species of Seiurus." — [C C. A,] 



S. noveboracensis, Gmel. [noevius, Bodd.) Water Wagtail. Water 

 Thrush. 



Dark olive brown above ; pale yellowish beneath ; thickly 

 spotted with color of the back ; feet dark ; bill, J inch. Length, 

 6 inches ; tail, 2| inches. 



"Arrives in May, and occasionally in April, frequenting banks 

 of creeks, and in movements similar to the more abundant 

 ' tiltup.' Breeds in June. Have disappeared by October 1st." 



S. motacilla, Vieill (/ttdowaantts.) Long-billed Water Thrush. Louisi- 

 ana Water Thrush. 



Same general color (less brownish) as preceding, but white or 

 pale buffy below, and less sharply spotted ; bill, f inch ; feet 

 pale. Length, 6 J inches ; tail, 2^ inches. 



" Less numerous than the preceding, but in every way is simi- 

 lar to it in habits. Seldom see more than one of this species, 

 where we find twenty of the noveboracencis." 



GEOTHLYPIS, Cab. 

 G. agilis, Wils. [Oporornis, Baird.) Connecticut Warbler. 



Olive green ; ashy on head ; brownish ash on throat and 

 breast ; yellow below. In fall more olive. Length, 5| inches ; 

 tail, 2J inches. A shy bird. 



"Arrives in May, and re-appears in September. Very rare. 

 Author has seen but two specimens. They were taken at differ- 

 ent seasons, but upon the same cypress tree. Probably prefers 

 cedar swamps and similar localities, which may account for its so 

 seldom being detected." — [C C. A.] 



G. formosa, Wils. Kentucky Warbler. 



Clear olive green ; bright yellow below ; crown and sides of 

 head and neck black, with rich yellow superciliary stripe, which
