and to Yai'mouth, N. S. ; principally with the view of observing 

 the habits of the birds breeding in those localities. The follow- 

 ing species were seen by us ; those marked with an * only at 

 Manan, and those marked with a f only at Yarmouth : — 



* Halicetus leucocephalus. A pair of full-plumaged birds were 

 seen every day at low tide, apparently watching for an oppor- 

 tunity of robbing the gulls of any thing worth the trouble. 



* Hypotriorchis columharms ? A bird which appeared to be 

 of this species was seen at Duck Island. 



* OtMS Cassinn. A nest of this bird was found by Mr. Cabot 

 in the midst of a dry, peaty bog. It was built on the ground, in 

 a very slovenly manner, of small sticks and a few feathers, and 

 presented hardly any excavation. It contained four eggs on the 

 point of being hatched. A young bird, the size of a robin, was 

 also found lying dead on a tussock of grass in another similar 

 locality. 



Chordeiles Virginianns. Only a few individuals seen. 



Chcetura jyelasgica. Quite common. A number of these birds 

 •were seen flying round the northeastern head of Green Island at 

 Yarmouth, and were, without doubt, nesting there, as they were 

 seen to fly in and out of the crevices of the rocks — the impos- 

 sibility of ascending the face of the cliffs prevented an actual 

 verification of the fact. 



Hirundo Americana. Not so common as either of the other 

 two species of the genus. 



Hirundo bicolor. Very common ; breeding in hollow stumps. 

 Incubation had generally commenced by the 2d of June. 



Hirundo rufa. By far the most common swallow, particularly 

 at Manan. The nests were almost universally built without the 

 projecting neck. Of late years, these birds, as they become more 

 habituated to building in sheltered situations, have nearly discon- 

 tinued their former habit of building their nests in a retort shape. 



Tyranmda Jlaviventris. This pretty little Flycatcher was more 

 numerous at Manan than at Yarmouth. Though apparently 

 unsuspicious, it was difficult to procure, in consequence of its 

 restlessness and its frequenting almost exclusively the thickest 

 clumps of alders and small firs. In its habits it approximates 

 more nearly to the warblers, than does any other species of the 

 genus that I am acquainted with. During our walks in the roads
