patent. Joints about twice as long as broad, but the lower ones 

 frequently shorter. Capsules orbicular, numerous, lateral, arising 

 from all parts of the plant and usually on short stalks. 



Chantransia compacta differs from C. chalybea in its compact, 

 firm habit, more crowded branches, shorter joints and more scat- 

 tered capsules. 



I am unacquainted with C. violacea, Kutz., and am conse- 

 quently unable to decide with certainty that this plant is not a 

 variety of that species ; but its difference in colour has induced 

 me to propose it as a distinct species. 



Kutzing in his ' Species Algarum ' mentions two other British 

 species : as I am unacquainted with them, I subjoin his descrip- 

 tions : — 



5. C. scotica (Kutz.). Caespite ceeruleo-chalybeo, majori, trichoma- 

 tibus 2X0'" crass i s > ramis ramulisque remotis patentibus elongatis ; 

 articulis diametro plerumque duplo longioribus. Kutzing, Phyc. 

 Gener. p. 285 ; Species Alg. p. 430. 



In Scotia legit cl. Klotzsch. 



6. C. violacea (Kutz.). Csespite minuto, violaceo, subgloboso ; tri- 

 chomatibus radiatim dispositis, rigidis, ramulis crebris approxi- 

 matis, abbreviatis, patentibus, subsecundis ; articulis inferioribus 

 diametro fere sequalibus superioribus 2-3plo longioribus. Kutzing, 

 Phyc. Germ. p. 231 ; Species Alg. p. 431.

XXV. — A List of all the Mosses and Hepaticce hitherto observed 

 in Sussex. By William Mitten, A.L.S. 



Besides the species not before described as British, this list will 

 be found to contain localities for others of rare occurrence or but 

 little known, and will show the comparative rarity of the more 

 common species. 



With very few exceptions all the species enumerated have been 

 gathered by the author himself ; most of the previously known 

 rarer species having been shown to him in their respective loca- 

 lities by Mr. Borrer, with whom he has examined many of the 

 most productive parts of the county, and to access to whose col- 

 lections he attributes chiefly whatever small amount of critical 

 knowledge he may possess of these beautiful plants.
