454 BULLETIN OF TIIE 



Surface specimens can be obtained during the dredging in tow-nets 

 of bunting, stretched over a hoop ; when under way very small 

 towing-nets raa_ occasionally be used also, if the speed is slow. 



The naturalists of the Swedish Josephine Expedition used also an 

 implement intermediate between the dredge and the tow-net, to obtain 

 the small swimming Crustacea, found near but not on the bottom. It 

 was a sort of very light dredge, made of hoop-iron, with the end-pieces 

 rounded off in such a way as to lift the edge of the net some distance 

 above the ground, so as not to scrape. The net was made of some 

 strong gauze-like stuff.
