BIGELOW. EXPLORATIONS IN THE GULF OF MAINE. 119 



phanes was taken at Stations 3, 7, 19, 25, 26a, 27, 32, in Eastport 

 Harbor, and two miles southeast of Duck Island, Mt. Desert: i. e., 

 Massachusetts Bay, the coast of Maine, Jeffrey's Bank, the region off 

 Casco Bay, and both sides of the deep basin. The oceanographic 

 data of the captures is as follows : — 



Station 25 surface temperature 56° salinity 32.34% 

 Eastport Harbor 



surface temperature 50° salinity about 32.5%o 

 Station 27 closing net 



40 fathoms temperature 45° salinity about 33.6%o 



Station 32 surface temperature 57° salinity 32.51%o 



Station 26a surface temperature 57° salinity about 31. 4%o 



Off Duck Island surface temperature 56° salinity about 32. 3%o 



Euthemisto compressa (Plate 5) . — This common boreal amphipod 

 occurred at twelve stations, so distributed as to show that it occurs 

 generally over the Gulf. In Massachusetts Bay it was taken once 

 (Station 44), and the records cover Piatt's Bank (Station 23), Jeffrey's 

 Bank (Station 25), off Cape Cod (Station 43), off Cape Elizabeth 

 (Stations 19, 22, 26b), off Seguin Island (Station 40), off Mt. Desert 

 Rock (Station 32), the Eastern Deep Basin, both off shore and near 

 shore (Stations 27, 36), and the neighborhood of Lurcher Shoal (Sta- 

 tion 31). It was not taken in the closing net, and the only two cap- 

 tures for which the horizon is known give the following data : — 



Station 27 surface temperature 59° salinity 32.6% 



Station 32 surface temperature 57° salinity 32.5% 



The other captures are from open hauls from intermediate depths. 

 The largest number were taken at Station 32, surface; Station 31, 

 at 55-0 fathoms; and Station 43, 35-0 fathoms. It was not found 

 on German Bank (Stations 29, 30). 



Clione limacina (Plate 5). — Apparently this large and striking 

 species is not abundant anywhere in the Gulf, at least in summer, 

 though it occurs in dense swarms in the Labrador Current and be- 

 tween Norway and Spitzbergen. Although it was taken at nine 

 stations, Nos. 2, 6, 7, 11, 14, 19, 22, 25, 32, i. e., in Massachusetts Bay, 

 off Cape Ann, between Jeffrey's Ledge and the coast, off Casco Bay, 

 over Jeffrey's Bank and off Mt. Desert Rock, the total number of 

 specimens was only sixteen, the most at any station, three; and it is 

 such a conspicuous object in the tow, that it is not likely that any were 

 overlooked. These stations are all near shore, the furthest out being
