Hob. West of Ireland. On the sandy bottom of the sea, in A l<> 

 fathoms water. Annual. Summer. 

 This handsome Cladophora, when growing, has very 

 much tlu* appearance, at first sight, of C. rectangularis, 

 so much s«> indeed, thai until the ramification be closely 

 Looked to, and the alternate or secund ramuli be observed, 

 it mighl be mistaken for thai species. It grows in the 

 Bame locality, and occurs in similar Loosely-bundled m 

 and often accompanies C. rectangularis in the same 'li- 

 lt possesses the same rigid substance as thai Bpecies, and 

 the same glossy, bright green colour, except when it is in- 

 fested with Cocconeis aggregata, which not only change 

 its colour hut prevent its adhering to paper. 



2 ( Ji. Hutchinsise (MissHJutchinfs Cladophora) ; filaments se- 

 taceous, of equal diameter throughout, rigid, crisp, glaucous- 

 green, fiexuous, tufted, bristling ; ramuli erecto-patent , Bimple 

 or furnished along the inner lace with Bhort processes of one 

 or two articulations ; apices vot obtuse ; articulations twice 

 or thrice as Long as broad, the joints contracted, ffarv. in 

 Hook. Br. Ft. v. 2. p. 357. (Atlas, PL LXIII. Fig. 297.) 



Conferva Hutchinsiae, Dillw. 



Hob. On the rocky bottoms of clear tide-pools, near Low-water 

 mark. Annual. Summer. Rather rare. 



A very beautiful and strong-growing specie-, discovered 



about the year L808, by the Late Bliss Hut chins, of Bally- 

 licky, near Bantry. It is very closely allied to C. di ' 

 bul the filaments are of greater diameter, the ramuli more 

 abundant ami shorter, ami the joints shorter and generally 



contracted at the dissepiments. 



2 ( J5. diffusa (The diffused Cladophora); filaments sub-setace- 

 ous, loosely tufted, rigid, dark or 1'nll green, fiexuous, much 

 branched ; branches distant, elongated, irregularly subdivi- 

 ded, or somewhat dichotomous, furnished towards the top 

 with a few Becund, Bimple ramuli ; articulations 3-4 times 

 Longer than broad, Both, Cat. Bot. v.2.p.2&7.t.7. (Atlas,

 Conferva diffusa, Roth. ('. distans, A<i. 



Il<ih. On rocks and Btones between tide-marks, and in clear 

 pools near low-water mark. Annual. Summer. 

 The Conferva diffusa of British authors is perhaps 

 scarcely sufficiently distincl from Cladopl 

 It is more Blender than the typical form of t]
