PosTSCBiPT, April, 1896. 



On the 12th of April I visited Little Bramingham, and found 

 that Tolypella intricata was absent from the small pool in which 

 it was last seen in April, 1895 ; it was also absent from the small 

 pond in Sundon "Wood, north of Bramingham, from which I 

 gathered it in the spring of every year from 1891 to 1895. On 

 the 18th of April I visited Totternhoe and found that this species 

 was absent from the pool at the Litany where it was first seen, the 

 place being now choked with a growth of coarse vegetation. It 

 was fairly plentiful in the second pool, where it grew scantily in 

 April, 1895. It also occurred sparingly in several places in the 

 old bed of the stream, which was diverted at the time of the 

 enclosure of the common. Chara contraria had disappeared from 

 its only known station in this district, where it was plentiful 

 in 1893.
