is Yound abundant in Bedford Basin, the inner expansion of Halifax Harbor, 
at a depth of thirty-seven fathoms. It ranges nearly to Greenland, and is 
also found on the coast of Northern Europe, where it is found in the 
Trondhjem Fjord, in latitude 65°, and south to the coast of Ireland. Its 
thermal range appears to be confined by the limits 34° and 45°. 
It breeds abundantly in our waters in summer time, numerous individuals, 
full of spawn, and young from half an inch upward, having been taken, 
from July to October, in various localities. 
The Pole Flounder has been pronounced, by all who have tasted it, a 
most delicious food-fish, resembling more closely than any other species on 
our coast the English Sole, having a great quantity of peculiarly flavored 
mucilaginous tissue about the base of the fins; it has never been taken by 
our fishermen, because, on account of its exceedingly small and weak 
mouth, it could not hold fast to an ordinary hook and line; and, should 
it ever come into demand, it will be necessary for our fisherman to intro- 
duce the English trawl-net. 
The Turbot or Steinbutt, RAombus maximus, and the Brill or Glattbutt, 
Fe. levis, do not occur in our waters, although many attempts have been 
made to prove that they do. The nearest representative of the Turbot is 
the Spotted Sand Flounder, Lophopsetta maculata, a species found from 
Bucksport, Maine, to Fort Macon, North Carolina, variously known along 
the coast as Water Flounder, Window-pane, and Daylight ; the latter name 
refers to the remarkable thinness of the fish, its flesh being so transparent 
that, when held to the light, the shadow of an object on the other side 
can be seen. Its flavor is good, but the amount of flesh is so small that 
it is of no consequence as a food-fish. There are other smaller represen- 
tatives of the family on the southern coast, and in deep water from Cape 
Cod southward, belonging to the genus Citharichthys, which, although 
edible, are never eaten. 
The Sand Dab, or Rough Dab, Aippoglossoides platessoides, also some- 
times known as the Rusty Flounder, is taken in winter by the line fisher- 
men of New England, and small quantities are doubtless brought to market 
and sold with other flat fishes without discrimination as to species. It of- 
ten attains the length of twenty to twenty-four inches, and the weight of 
two to five pounds, and is, in all respects, a desirable food-fish, being 
highly esteemed on the other side of the Atlantic. In summer, individ- 
uals of this species are to be found only in very deep water, thirty fathoms
