OONOPID^:. 



In the Summer of 1^94 I found on my desk at Sea Cliff, N. Y. , 

 a little spider, which, when touched by the pencil, leaped back- 

 ward an inch to an inch and a quarter. It was collected, and to 

 my surprise, belonged to Orckestina, the species of which are 

 known to leap, and at least one of which occurs in southern Europe.
