 means of nesting-boxes, &c. Sparrow-Hawk, Nightingale,* Stone-

CEUSTACEA. 



Distribution of the Crayfish in Bedfordshire. — The Crayfish 

 (Potamobius pallipes) is first recorded for this county by the Lysons 

 (' Magna Britannia,' p. 21) in 1806, they including some in a list of 

 the "fish" that are taken in the river Ouse; and, secondly, by 

 G. C. Gorham (' History of St. Neots,' p. 140) in 1820, who refers to 

 such as one of the " fish " which ordinarily occur in this river. 

 Whether the Crayfish was then of really common occurrence neither 

 authorities enlighten us, and not improbably the latter writer took 

 his information from the Lysons' work. In recent years, so far as the 

 river Ouse is concerned, it must at least be very rare. I have never 

 heard of it being taken from that waterway. It is recorded by 

 J. Saunders (' Victoria History, County of Beds,' vol. i. p. 91) in 

 1904 as abundant in the river Lea, south of Luton Hoo — a very 

 restricted locality, as only about a mile of this stream is within the 

 county. It has also been reported to me as found not infrequently 

 in the river Ivel below Shefford. I can now further extend its 

 distribution, as one measuring 5f in. from tail-fan to top of the 

 antennae I took on October 25th last from the eel-trap at my mill 

 at Blunham. — J. Steele Elliott (Dowles Manor, Salop). 



* This species has only nested in a single instance.
