Linnaean Society" — viz., on a new species of Utricularia from 

 Sonth America ; on a new genus of Hamamelidece^ and a short ac- 

 count of the British Herbarium belonging to the Linnsean Society. 

 His friends in the north will be glad to hear, that his scientific 

 attainments, which were well known to them, have also been 

 recognised at Kew, and that he has, within the last few months, 

 obtained a satisfactory and permanent appointment there. Mr. 

 George S. Brady has, during the past year, found on our coast 

 many rare and hitherto unobserved species of Algce^ and has, at 

 the request of the committee, undertaken to prepare a general 

 catalogue of this portion of the Flora for our " Transactions." In 

 a letter on the subject, addressed to me, he says: — " The following 

 are a few notes respecting some of the more interesting forms w^liich I 

 have found during the past year. I am not aware that any of them 

 are previously recorded from this coast, at least not by Dr. John- 

 ston or Winch, whose works contain, I believe, the only published 

 lists of our local Alg . 



Callithamnion Daviesii, not uncommon on the smaller Algce; a 

 beautiful microscopic parasite. 



C. sparsum^ at Roker, on Cladophora rupestns. 



C.floridulwJi, at Roker and Whitley. 



C. HooJcein, on other Algce. Occasionally all along the coast. 



C. polyspermum. Frequent on perpendicular rocks ; I think it 

 probable that this is erroneously noted by Winch as C. 

 purpurascens. 



Ceramimn acanthonotum. 



Cer. DeslongcJiampsii. 



Cer. hotryocarpum. Near Seaham Harbour; rare. 



Cer.flahelligerum. St. Mary's Island; rare. 



Cladophora arcta. On the North Pier, Sunderland. 



Ectocarpus sphcerophorus. Seaham and Hendon. 



Enteromorpha clatlirata. Near Sunderland. 



Laminaria fascia 1 ^-r r. i i i 

 / Near bunderland. 

 L. stenophylla. ) 



Myrionema punctl forme. Near Seaham. 



Polysiplionia violacea. Whitley. 



Sphacelaria filicina. Near Seaham ; a very beautiful plant, and 



I Not uncommon.
