Sorry, no etymologies found.
On the east coast of North America occurs _P. glacialis_, in which the scales of the male are strongly spinulate and those of the female smooth.
Plaice and Dab are taken together on the same ground, and nothing has been discovered to indicate that the spinulate scales of the Dab are adapted to one peculiarity in habits or conditions, the spineless scales of the Plaice to another.
On the coast of Alaska females of this species seem to be more spinulate than elsewhere.
_P. cynoglossus, _ the Witch or Pole-dab: head and mouth smaller than in the Plaice, eyes rather larger; scales all alike and uniformly distributed, slightly spinulate on upper side, smooth on the lower; blister-like cavities beneath the skin of the head on the lower side.
The Plaice, on the other hand, are smaller than those of the North Sea, and the _males_ have the scales spinulate over a considerable portion of the upper side.
