34 THE BIOLOGICAL REVIEW. 



(June 25.) Nest on the ground at the foot of a small bush ; 

 composed of leaves and vine-bark, lined with fine black rootlets 

 and plant stems. It contained three fresh eggs, averaging 

 •88 x "70 in size. 



Ghcetura pelagica. — (June 7.) Nest formed of coarse twigs, 

 fastened together with the saliva of the birds, placed in an 

 unused chimney of a house in the suburbs of the city. It 

 contained five eggs, slightly incubated. Average size, "82 x -54. 



Ardetta exilis. — (June 12.) Nest — very compact for this 

 species — placed in a clump of green rushes ; composed of small 

 rushes and reeds, with a thin lining of finer pieces of the same. 

 It contained four fresh eggs, averaging 1-23 x -94. This species 

 evidently rears two broods in the year in this locality, as I have 

 found eggs as late as August. 



Actitis macularia. — (June 16.) Nest — a shallow depression 

 in the ground, near the lake shore — thinly lined with grass,, 

 containing four fresh eggs, averaging 1*28 x -95. 



AZgialitis vocifera. — (June 18.) Two nests, or rather nesting 

 sites, of the Killdeer were found on Toronto Island, one con-

 eggs were laid in a slight depression in the gravel, no other 

 sign of a nest being visible. 



Vireo olivaceus. — (June 19.) Nest composed of strips of bark 

 and flexible plant stems, lined with a little fine dry grass, and 

 fastened by the rim to a young oak sapling, about seven feet 

 from the ground. It contained three fresh eggs, averaging 

 •84 x -6o. 



Myiarclms crinitus. — (June 22.) A nest of this species was 

 found in the suburbs of the city, placed in the hollow of a live 

 apple tree, about twelve feet from the ground. The cavity, 

 which was about ten inches in depth, was lined with fine 

 grasses and plant stems, and contained five fresh eggs, averaging 

 •92 x "67 in size. 



Chordeiles virginianus. — (June 28.) Two eggs of this species 

 were found laid in the gravel on the flat roof of a house in the 

 outskirts of the city, averaging 1*20 x -86. 



Contopus virens. — (July 1.) Nest placed on the horizontal 

 limb of an apple tree, about twelve feet from the ground, formed
