SEA-B UTTERFLIES.

Blessed be Gambrinus ! Without his invention, nobody per- 

 haps would have thought of furnishing beer-glasses with fixed 

 handles. The net, which was filled with a mass of swimming 

 creatures that could not escape, was raised above the water till 

 there was room to dip out of it with a beer-glass. We have been 

 fortunate, for we have fallen upon a swarm of needle-butterflies,

Creseis acicula (Fig. 3), and have caught a considerable number 

 of them in our glass, besides other shelled species, such as Hyalea 

 tridentaia (Fig. 4), and Cleodora lanceolata (Fig. 5). But it is best 

 to isolate them, and to separate from among the other little trans- 

 parent minnows certain crustaceans, some of which might take a 

 notion to attack the butterflies and eat them. Then we turned 

 toward home. The hour and a half occupied in the journey back 

 was spent in selecting out.
