The distribution of the two species is not exactly the same, though 

 roughly parallel, for while compressa was taken at practically every 

 station where bispinosa occurred, it alone occurred off Cape Cod and 

 on George's Bank, near the coast south of New York (Station 10075)

off Massachusetts Bay (Stations 10087, 10088), and, in general, in 

 the coast water north of Cape Ann (Stations 10100, 10101, 10103, 

 10104, 10105). Of course horizontal hauls can not afford an accurate 

 idea of its abundance, but they do show that it swarmed on the surface
