and more especially by the “Albatross,” which has invariably, during 
more than six seasons, used the surface tow-net and an open deep-sea 
tow-net in connection with its other work, and which has been duly 
recorded in the Annual Reports of the United States Fish Commission. 
As early as 1865, in the “Seaside Studies,” a sketch of the pelagic 
surface fishing off the coast of Massachusetts was given. In addition 
to the chapter on the Pelagic Fauna of the East Coast of the United 
States given in the “Three Cruises of the Blake,” papers on the surface 
fauna of the Gulf Stream, on the pelagic stages of fishes, and numerous 
notices scattered through various embryological and faunistic memoirs,} 
there is an account of the fauna of the surface water of the Gulf Stream 
off New England, drawn up by Professor A. E. Verrill? from the material 
collected by the United States Fish Commission during many seasons’ 
work, up to 1883. 
The “ Albatross” used a number of muslin nets (silk bolting cloth), 
known as “trawl rings,” attached to the ends of the trawl frame, so as 
to be somewhat above the bottom, and many pelagic species have been
