taken possession of the upper reaches of the river, but it has become a 

 common species here, whilst others have decreased, and I have known 

 many instances of late years where fish of four or five pounds have been 

 " brought to bank." — G. B. Corbin (Eingwood). 



[This is unfortunately not the first record of Chub having been care- 

 lessly introduced, and this fish in a Trout stream is an unwelcome in- 

 habitant. For the Chub is a predaceous fish, being frequently caught 

 by anglers when spinning, and I have personal knowledge of several 

 having been taken when fishing with a Gudgeon. Still the Chub is 

 one of the most interesting fishes if its habits are studied in the way 

 ornithologists conduct their field-work. " Once a Chub-hole always a 

 Chub-hole " is an axiom with anglers, and it is in some ways one of 

 the most crafty of fishes. When a Chub has been played and landed 

 it is not worth while fishing the same spot for some time afterwards, 

 and those who use the natural fly best for this fish are the quietest and 

 most unobtrusive of anglers. Of course, winter fishing in swollen and 

 coloured water does not sufficiently give this impression. The Chub 

 is good to catch and very indifferent to eat, but its bionomical narra- 

 tive has not yet been written. — En.] 



CRUSTACEA. 



Rare Species at Yarmouth. — I have to thank Messrs. Boulenger 

 and Caiman, of the British (Natural History) Museum, for confirming 

 my suspicions as to the identity of two stalk-eyed crustaceans, which, I 

 am pleased to say, are interesting additions to my East Norfolk list, 

 viz. Portunus holsatus, the Livid Swimming Crab, and Pandalina brevi- 

 rostris, recorded by Bell as Thompson's Hippolyte. Of the former, I 

 met with a very small example in the summer, and, being struck with 

 the delicacy of its markings, and its general appearance, placed it aside 

 in formalin, so as to be able to compare it with any others that might 

 turn up. One, considerably larger, was subsequently taken by a 

 shrimper friend, and placed by him in spirits. He said that he very 

 rarely indeed had met with anything like it. Pandalina I picked out 

 of a handful of siftings that had been riddled, and preserved for me by 

 another shrimper. On Oct. 27th, when rambling by the tide-mark 

 from Gorleston, I was surprised at the numbers of Shore-Crabs (Carci- 

 nics mcenas) washed up dead and dying, and could assign no reason for 

 the phenomenon. I picked up a couple of freshly dead Edible Crabs 

 {Cancer pagurus) among them, derelicts from the North Norfolk grounds.
