Thalassidroma I ilsoni.—Donap. 
Wilson’s Petrel. 
I found this bird on one occasion in the Dela- 
ware Bay, near Lewistown, Delaware, the weather 
being very clear andcalm. I shot one when the 
Captain told me there would a storm Lefore we 
reached the land. I laughed at him, but to my 
surprise in less than half an hour I witnessed one 
of the worst blows I ever saw, and we were 
obliged to run into a creek for shelter. 
Thalassidroma Pelagica —Lonap. 
Mother Cary’s Chicken. 
I shot one of these birds on the Schuylkill 
River kelow the Market Street bridge, Philadel- 
phia. There was a large flock of them and 
when [I shot the one the others made off. They 
must have been blown in by a heavy storm.

ows below Broad Street, Philadelphia, I shot at 
aflock of Black-bellied Plover and killed three
