Hob. Bogs at Fisher's Castle, Tunbridge Wells: Mr. 

 Jenner. 



Lyngbye describes this species as follows : " Mass gela- 

 tinous, cylindrical, solitary, solid, floating on the surface of 

 water, an inch or two long, colour commonly watery, pel- 

 lucid, except as regards that which is owing to the internal 

 granules, which are of a delicate green colour. Substance in 

 the highest degree lubricous, adheres, in drying, to paper." 

 Brebisson, however, states that it attains to the remarkable 

 size of one or two feet in length, and from six to eight inches 

 in thickness. 



" Specimens communicated liberally by Cl. Brebisson 

 and Lenormond are five inches long, and although closely 

 adherent to paper, yet manifest greater solidity of the super- 

 ficial stratum over the internal substance. For being lacer- 

 ated by compression, they exhibit the interior effused sub- 

 stance hyaline, and the exterior pellicle more intensely 

 coloured and opaque, and divided into irregular fragments. 

 In the interior substance uniform, very minute globules are 

 imbedded, scarcely measuring the two thousandth part of a 

 millemetre ; but the exterior pellicle is constituted of globules 

 somewhat larger, covering a diameter of the two hundred and 

 fiftieth part of a millimetre, in which oblong vesicles, alto- 

 gether filled with minute globules, from the twentieth to the 

 twenty-fifth part of a millimetre long, are mixed." 



What appears to me to be at least a variety of this 

 species was sent to me by the Rev. M. J. Berkeley. The 

 fronds were globose, but smaller and less solid than those of 

 C. hyalina in its usual state, and the globules larger. See 

 PL LXXVIII. fig. 5.
