CATALOGUE OF CANADIAN BIRDS. 661 
it contained showed by their galvanized appearance that they 
were far advanced in incubation, and I did not remove or revisit 
them; the cavity in which this nest was placed was small, the bird 
had either found it ready for her purpose, or had partly enlarged 
it, and the nest itself was made of weed-stems, dry grass, animal 
hair, and “hair-moss.’’ Usually when the cavity is large, this 
species uses a quantity of dead leaves in the construction of her 
nest. (W. L. Kells.) This bird is commoner at Sharbot lake 
than on the St. Lawrence; here I found a number of pairs 
breeding in 1903; one pair had a nest and young on a small island, 
June 12th, 1903. I also found an unfinished nest on a small 
island in Mosquito lake, North Frontenac, May 28, 1905. (Rev. 
C. J. Young.) 
675a. Grinnell Water-Thbrush. 
Sevurus noveboracensis notabilis RipGw. 1885. 
We saw our first water-thrush at Painted Stone portage. It was 
close to the edge of the water and was running through the under- 
growth which fringed the foot of a cliff. On the afternoon of the 
same day, June 26th, we noted another at Robinson portage, and 
on June 30th, a third at Oxford lake. When we arrived at Oxford 
House we found the species rather common, and from there to 
York Factory, as we descended the rivers, its sprightly song was 
heard daily. A pair seen at a portage on Hill river, July 7th, were 
feeding young just from the nest. Three specimens were taken in 
the marshy woods about York Factory, where the species was com- 
mon July 11th to 17th, and one was taken August 8th by Alfred 
E. Preble on Churchill river about 15 miles above Fort Churchill. 
These proved to be intermediate between novaboracensis and nota- 
bilis, but nearer to notabilis. (E. A. Preble.) A summer resident 
along watercourses in Manitoba. They were very abundant at 
Humphrey lake on August oth, 1884. Evidently preparing to 
migrate. (EF. T. Seton.) A common migrant at Aweme, Man., a 
few may breed. (Criddle.) An abundant migrant and an abun- 
dant breeder about all the water-courses in Manitoba and noted 
everywhere in wooded sections along the G.T.P. Ry., west to 
Edmonton in 1906. (Atkinson.) Two specimens from Chemawa- 
win, near Grand Rapids of the Saskatchewan, agree more nearly 
with the species than with S. novaboracensis notabilis. (Nutting.)
