Concerning the Squilla ^quie Dulcis. Bij Dr. Richardson,* F. R. S. 

 N°433, p. 331. 



Dr. Richardson has observed what he does not remember to be noticed 

 by any naturali.^t, viz. tlie great destruction made among the small fry of 

 fish by the squilla aquae dulcis, which abound in most standing waters. In a 

 small breeding pond near his house, where he had formerly plenty of small 

 carp and tench every year, and of late scarcely any young breed to be met with, 

 his gardener observed one of the squilla?, with a carp in its mouth almost as 

 large as itself; and has since observed these insects hunting among the weeds, 

 and vigorously pursuing the small fry. The Dr. ordered the gardener to catch 

 some of these insects, and bring them home alive, with some of the smallest 

 fish he could meet with. He put them together in a large basin of water. 

 The insects were so rapacious, that they fell upon the fish immediately, and 

 destroyed several in his sight; and before morning had devoured all that were 

 in the basin.
