FISH NOTES 247 



Double Turbot already referred to. Both sides 

 were coloured. At the same time I examined a 

 Smeared Dab (Pleuronectes microcephalies) normally 

 shapen but with both sides coloured. 



OTHER DEFORMITIES 



Just as the Cod and some other "round" fishes 

 are afflicted with deformities in the anterior portion 

 of their bodies, so there are to be found malformations 

 near the tail. On Breydon in August 1901 a Smelt 

 was netted, the posterior end of which suddenly 

 turned up just above the anal fin, and having formed 

 a kind of apex on the back, as suddenly descended, 

 after describing a rather pointed arch. The tail was 

 also out of proportion, and forked very much like 

 that of a Herring. 



A Haddock with a crooked back, exactly corre- 

 sponding with the Smelt, came to hand in March 

 1902; and in June 1902 I obtained the tail of a 

 Skate which, in curves, zigzagged the whole of its 

 length, describing three half-circles to the left and 

 the same number to the right. 



On one occasion I obtained an Eel zigzagged the 

 whole of its length in a similar manner.
