SYSTEMATIC ACCOUNT. 83 



from one to four : C. prolifera (T. glomerata), C. 

 polysperma (T. intricata), C. Borreri (T. prolifera), and 

 C. Smithii (T. glomerata), the two latter being de- 

 scribed as new ; and G. pnlcliella and 0. Hedwigii 

 were united as G. fragilts Desv. In Johnson's ' Fern 

 Allies ' (1855) there is nothing new, but plates are 

 given of eleven species, some of which are not good. 

 In 1862, Babington, in Seemann's ( Journ. of Bot./ 

 describes C. alopecnroides as British. Mr. Baker, in 

 the * Botanical Exchange Club Report' for 1867, gives 

 a revision of the Tolypellas, reducing the certainly 

 British species to two, giving G. Borreri as the var. 

 robustior of G. intricata, and mentioning C. nidifica 

 as possibly British. In the ' Journ of Bot.,' 1877, 

 Dr. Trimen adds G.fragifera to the list." 



The following notes will supplement the fore- 

 going : 



In 1878 G. connivens was added to the British list 

 through the identification of a specimen in Herb. 

 Borrer collected fifty years earlier. 



In 1880, in " A Review of the British Characese," 

 already cited, an attempt was made to give an account 

 of all the then-known British species, with illustra- 

 tions and some particulars as to their variation and 

 distribution. In the autumn of the same year Nitel- 

 lopsis obtusa (Cham stelligera Bauer) was discovered 

 by Mr. Arthur Bennett in one of the Norfolk Broads, 

 and was described and figured in the ' Journal of 

 Botany : for January, 1881. 



In December, 1881, there appeared in the ' Journal 

 of Botany : the first of a series of nine papers by H. 

 & J. Gr., entitled " Notes on British Characese," the last 

 being published in 1898. These included descriptions 

 and figures of fresh species added to the British list, 

 records for fresh counties, and odd notes. In the 

 first instalment G. baltica (var. affinis) was described 

 and figured from a plant first collected in 1876 by the 

 late James Cunnack, near the Lizard. In the same 

 paper C. contraria was added, with a figure from a
