tion 23, 20-0 fathoms, six specimens, and Station 40, 20-0 fathoms, 

 one specimen. The importance of these captures has been noted 

 (p. 106). 



Euchacta norvegica. — This species has been detected at Stations 7, 8, 

 12, 23, 27, 31, 32, 36, 43, and from two miles off the Isles of Shoals, i. e., 

 Massachusetts Bay, Ipswich Bay, both arms of the deep basin, off 

 Cape Cod, on Platts' Bank, off the Nova Scotian Coast and the coast 

 of Maine. Thus Euchaeta norvegica was generally distributed over 

 the Gulf, though of irregular occurrence. The only localities where 

 it was abundant were at Station 36, in a haul with the open net at 

 seventy-five fathoms, and at Station 43, where many were taken in 

 the closing net at eighty-five to sixty fathoms, forming the bulk of the 

 haul. As most of the hauls were taken from intermediate depths, 

 neither the horizon from which the specimens came, nor, consequently, 

 the precise salinity and temperature can be determined. The known 

 salinities and temperatures are: — 



Station 32 surface temperature 57° salinity 32.51%o. 



Station 43 85-60 fathoms temperature 42° salinity about 33.5%o. 



Euchaeta was only once taken in a surface haul (Station 32), and 

 the fact that it was most abundant in deep hauls agrees with its occur- 

 rence in the Norwegian Sea. 



Anomalocera patersoni. — This copepod was taken at Stations 13, 

 24, 26b, 27, 30, 37, 40, 41, 42, being thus generally distributed over the 

 western side of the Gulf, in Frenchman's Bay, and on German Bank. 

 But it was not taken in Massachusetts Bay, nor over the off-shore por- 

 tion of the Gulf as a whole, its only occurrence far from land being 

 at Station 24. It was taken in surface hauls, never in the closing net, 

 only once (Station 37) in the open net from intermediate depths. The 

 temperatures at which it occurred ranged from 52°-61°, the salinity 

 from 31%o to 32.7%o- The fact that it was a purely surface form 

 makes it probable that it was more widely distributed than our records 

 show, for comparatively few hauls were made at the surface with the 

 large net. But it was conspicuously absent from the surface hauls 

 made at Stations 27, 28, 29, 31, 32, a fact showing that it is not 

 brought to the Gulf by the indraught of oceanic water which is no- 

 ticeable over the region covered by these stations. 



Meganydiphanes norvegica. — The following notes are based only 

 on the occurrence of large adults of unmistakable identity; probably 

 the list of localities will be largely augmented by identification of 

 the large series of young schizopods. Thus restricted, Meganycti-
