THE BIRDS OF NEW JERSEY. 285 



675a Seiurus noveboracensis notabilis (Grinnell). 

 GrinnelPs Water-Thrush. 



Differs from the last in larger size and darker, sootier color above. Length, 

 5.50-6.50. Wing, 3.15. 



One specimen was taken at Raritan, May 30th, 1889, 1 and another 

 by Mr. W. E. D. Scott, at Princeton, September 10th, 1879. 2 



676 Seiurus motacilla (Vieillot). 

 Louisiana Water-Thrush. 



Adults. Length, 5.75-6.25. Wing, 3.15. Above, olive-brown, darker on the 

 head and grayer on the back ; a white line over the eye ; below, white, streaked 

 on the breast and sides with brownish-black. In autumn the sides are washed 

 with buff. 



Differs from the preceding species in the absence of spots on the throat and 

 in the white color of the under parts as contrasted with the pale lemon tint of 

 8. noveboracensis. 



l^oung in first summer. Similar, but throat as well as breast and sides 

 streaked, and under tail-coverts and sides cinnamon. 



Nest under an overhanging bank of leaves and rootlets; eggs, four to six, 

 white, speckled with reddish-brown, .76 x .62. 



Common summer resident in the lower Hudson Valley and along 

 the upper Delaware; very rare migrant in south Jersey. Arrives 

 April 15th, departs September 1st. 



While common along the Delaware from Black's Eddy to Port Jer- 

 vis, on the lakes of Sussex and Passaic counties (Rhoads) and on 

 the lower Hudson, this Water-Thrush seems to be rare elsewhere in the 

 State. Mr. Miller has found it, in summer, occasionally in notches of 

 the trap ridge, north of Plainfield, and Mr. Babson secured a fledge- 

 ling, near Princeton, June 12th, 1900. Dr. Dwight found it, in sum- 

 mer, at Lake Hopatcong, and Mr. P. B. Philipp at Newton, Sussex 

 county. 



In southern New Jersey it seems to be unrecorded. 



In habit, song and appearance it resembles the other Water-Thrush, 

 but may be distinguished by the white instead of yellow underparts 

 and the lack of spots on the throat.
