swim in large shoals. Their spawning-season is at the 

 end of April or the beginning of May ; and so prolific are 

 they, that a specimen weighing half a pound has been 

 found to contain 280,000 ova. The eggs are deposited in 

 strings which hang about the weeds and rocks, and when 

 seen through a bright sunlight present a beautiful appear- 

 ance, almost resembling festoons of pearls.

 and in other lakes in the North of Europe. Deformed 

 Perch are also found in Llyn Raithlyn, in Merionethshire. 

 Such a fish is figured in the volume of Daniel's ' Rural 

 Sports ' devoted to Fishing and Shooting, p. 247. Perch 

 almost entirely white inhabit the waters of particular soils ; 

 and I am indebted to the kindness of G-. S. Foljambe, Esq., 

 of Osberton, for specimens of a variety of Perch from 

 Ravenfield Park ponds, near Rotherham, in Yorkshire, the

 London, were of a uniform slate-grey colour with a silvery 

 tint ; and this peculiarity of colour is retained when the
