by gales of wind or storms. Several species 

 may be taken in pools, ditches, stagnant waters, 

 and tbe clearest streams ; and many of the 

 minute species have the appearance of bivalve 

 shells. The smaller species of this sub-class 

 are best secured in spirits, but the larger as 

 hereafter directed. [PL I, fig. L]
