602 The American Naturalist. [June, 
to require special comment. Similar injuries are reported by Mr. 
William T. Davis and Mr. Charles W. Leng, as observed, especially on 
the leaves of oaks and maples, at Newfoundland, N. J., where a high 
ridge furnishes opportunity for exposure. 
With easterly storms so prevalent on our coast, it is strange to find 
so conspicuous a result from a storm possessing no unusual character- 
istics, and the simplest explanation would obviously be that it occurred 
just at a time when many leaves were sufficiently young and tender to 
receive the injury, yet old enough to survive it—a combination that 
might not often occur. 
Mr. Wm. T. Davis exhibited specimens of dragon-flies and read the 
following : 
Two Additions to the Local List of Dragon-flies——The dragon-fly, 
Libellula azxillena Westwood, form vibrans, was quite numerous last 
August in various parts of the island, both near ponds and in wood- 
land. If persistently disturbed, they often flew into the highest trees. 
The first one was seen on August 4th in the valley of Reed’s basket- 
willow swamp. In capturing it the abdomen was knocked off, and the 
remainder of the insect, true to what I afterward found to be the cus- 
tom of the species, flew into a tree. Several missles induced it to 
change this perch for a less elevated one, and it was finally placed in 
the cyanide bottle. Previous to the summer of 1894, this dragon-fly 
had not been seen on the island, and it is an interesting fact that it 
eventually came in such numbers. 
Two small specimens of Diplax semicincta Say, were taken on the 
15th of last July at the small ponds of the old iron mines near Four 
Corners. This locality is also the only one on the island where Nan- 
nothemis bella Uhler has been found. 
With these two additions, the species belonging to the sub-family 
Libelluline, so far collected on the island, number twenty-two. Mr. 
Calvert reports but twenty-four species from the vicinity of Philadel- 
a. 
Minor Notes—Mr. Arthur Hollick reported that an oppossum was 
captured on December 6th, at New Dorp, by Mr. Richard Britton. It 
was found in a shallow burrow in the ground, near the foundation 
walls of an old ruined house, and was easily unearthed. The animal 
was killed and has been sent to a taxidermist for mounting. From the 
appearance of the locality, Mr. Britton is of the opinion that a colony 
of the animals is living there. 
Mr. Wm. T. Davis exhibited a small Indian stone paint pot, recently 
found at Tottenville. This is the first utensil of the kind reported 
from any of the collections made on the island.
