awl in bad condition : circumstances not favourable to propa- 
gation. Farther observation enables us to remark, that a 
delayed propagation of ono Season is not necessarily followed 
by a late spawning in the next. 
FLAT FISHES. 
PLAICE. Plalessa Vulgaris. Jenyns, p. 454. Yarrell’s 
Br. F., vol. 2, p. 209. Common, but far less abundant than 
formerly ; a remark which may be applied to all the Flat 
Fishes, and to be accounted for by the destructive influence 
of Trawl fishing. 
FLOUNDER. P. Flesvs. Jenyns, p. 455. Yarrell’s Br. 
F., vol. 2, p. 215. Fluke, a name derived from its form, as 
Flounder is from its motion. Varieties, in which all the 
organs are on the reversed side of the body, are not uncom- 
mon in all the flat Fishes ; but more frecjuently in this 
species than in the others. Sometimes also the under sur- 
face is of the colour and texture of the upper, and in a few 
instances the upper surface has resembled the lower. 
DAB. P. Limanda. Jenyns, p, 456. Yarrell's Br. F., vol. 
2, p. 219. Common. 
SMEAR DAB. P. Microcephalus, Jenyns, p. 457. Yarrell’s 
Br. F., vol. 2, p. 221. Not uncommon. 
HOLIBUT. Eippoglossus Vulgaris. Jenyns, p. 460. Yar- 
rell’s Br. F., vol. 2, p. 230. Mr. Yarrell by mistake ex- 
cludes this from the Cornish Catalogue ; it is however not 
uncommon, and one that was weighed for my satisfaction, 
amounted to 120 pounds, its length being six feet. As 
food it is far below the other flat Fishes, and differs from 
the rest in being very powerful when hooked, as well as very 
voracious. 
TURBOT. Ple&ronectes Maximus . Jenyns, p. 461. Yar- 
rell’s Br. F., vol. 2, p. 233. This Species, so well known 
to the Epicure, sometimes ascends to the surface over deep 
water, and remains several hours stemming the tide, with- 
out advancing. 
BRILL. P. Rhombus. Jenyns, p. 462. Yarrell’s Br. F., 
vol. 2, p. 240. Kite. Common. 
TOPKNOT. P. llirtus. Jenyns, p. 463. Yarrell’s Br. F., 
vol. 2, p. 243. Not uncommon, and contrary to the habit 
of its Congeners, keeping among rocks. It is probable that 
the P. Punctatus is also a Cornish Species. 
WHIFF. P. Mcgastoma. Jenyns, p. 464. Yarrell’s Br. 
F., vol. 2, p. 251, where however the oeellated marks 
round the coloured margin are omitted, although I never 
saw a recent Specimen without them. Carter, and Mary 
Sole. Common. 
MEGRIM. P. Amoglossus. Jenyns, p. 465. Yarrell’s Br. 
F., vol. 2, p. 254. Perhaps not so rare, as disregarded.
