and in bad condition i circumstances not favourable to propa- 

 gation. Further observation enables us to remark, that a 

 delayed propagation of one Season is not necessarily followed 

 by a late spawning in the next. 



FLAT FISHES. 



PLAICE. Pialessa Vulgaris. Jenyns, p. 454. Yarrell's 

 Br. F., vcl. 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. Flesus. 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 frequently 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. Microccphalus. Jenyns, p. 457. Yarrell's 

 Br. F., vol. 2, p. 221. Not uncommon. 



HOLIBUT. Hippoglossus 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 boing very powerful when hooked, as well as very 

 voracious. 



TURBOT. Pleuronectes Maximvs. 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. Hirtus. 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. Puuctatus is also a Cornish Species. 



WHIFF. P. Mcgastoma. Jenyns, p. 464. Yarrell's Br. 

 F., vol. 2, p. 251, where however the ocellated marks 

 round the coloured margin are omitted, although I never 

 saw a recent Specimen without them. Carter, and Mary 

 Sole. Common. 



MEGRIM. P. Arnoglossus. Jenyns, p. 465. Yarrell's Br*. 

 F., vol. 2, p. 254. Perhaps not so rare, as disregarded.
