saved. The birds live entirely about the bluffs and even seek their food under the 

 huge bowlders at the bases of the cliffs, where they enter the crevices and, remaining 

 under some minutes, reappear some ten or more feet away. Eggs: "Dull white with 

 a very few minute dots of reddish, so few and small as to be easily overlooked, 0.G8 

 by 0.51, 0.60 by 0.50."— (^ Hew.) No. 54447, im. S , Type, August 17, 1868, St. George,

Similar to M. erythrogastra, but larger, with longer wings and tail and relatively 

 smaller bill; white areas of tail larger, with narrow white outer edgings to the 

 leathers. 



Walking along the bluffs near the village of St. George on May 28, 1890, with 

 Mr. Ed. Lavender, we saw a swallow skimming along the edge of the bluff, catching 

 the dies which the warm sun had enticed from the crevices of the rocks. Shortly 

 afterwards it flew just over my head while among the houses of the village. Drs. 

 Noyes and Hereford, who have each spent more than ten years on the islands, assured 

 me that a swallow was unknown there, but later in the evening I had the opi)ortuuity 

 of showing them the bird on another jjart of the bluff. It remained about the village 

 for nearly two weeks. On .June 4, while standing on Black liluffs, St. Paul, 1 watched 

 a swallow coming in to the land and then tly northward up the island. 



I found a nest at Unalaska, on August 13, containing three large young, a male 

 and two lemales, and secured the adults also. The nest is of mud held together by 

 grass rootlets. It is 9 inches wide and 4 inches deep; the cavity is 2^ inches in 

 diameter and 1^ inches deep. Grass rootlets encircle the cavity, Avhich is well-lined 

 with gull and raven feathers. It was built in a large cavity, almost a cave, of a rock 

 on a hillside, and was placed on the slightly sloping face of the back portion, about its 

 center. A slight ineiinality of the rock face was suHicient to hold it in place. To 

 enter the cavity the birds had to Hy to the face of the rock and then dip downward 

 between the rock and many tall plants, which effectually hid the opening. I saw no 

 others.

On June 3, 1890, in a grassy patch near Lukanin Beach, on St. Paul, I several 

 times flushed a s]xirrow which I identified as this species, having seen and collected a 

 number several days before at Unalaska.
