Remarks on some English Fishes, with Notices of three Species, new to the British Fauna. By William Yarrell, Esq., F.L.S., bjc. The season for Whitebait fishing having expired soon after the send- ing my former remarks on that subject for insertion in the XlVth Num- ber of the Zoological Journal, I waited with some anxiety for the period when nets of small meshes might legally be worked at the mouth of the Thames for Smelts and Sprats, in the hope of obtaining further evidence of the distinction between Whitebait and Shads; and in this expectation I was not disappointed. I obtained, but in small numbers only, both adult Whitebait in roe, and some young ones ; but it appeared that the large shoals of this fish, like all those which visit the fresh water for the purpose of depositing iheii spawn, had, with their fry of the year, quitted the river and returned to the deep. As late as the month of November I obtained several small Shads, only 2A inches in length, which illustrated another point in the history of that fish. We are told by Baron Cuvier and M. Valenciennes, in the second volume of their work on the Natural History of Fishes (p. 25) that a Perch of 7 inches is in his third year; and I therefore felt convinced that these young Shads, only 21 inches in length when taken in November, were in reality young fishes of the same year, and that the young Shads of 4 inches in length, obtained in the months of July and August preceding, were the young fishes of the year before, the greater part of them having arrived at the length of 4 inches Vol. IV.
