Griffithsia Schousboei (Mout-dg.), repens, intricata, filis dichotomis articulato-constrictis, articulis elliptico-sphsericis e geniculis radicellas hyalinas emittentibus. " The absence of fructification causes me to doubt if this is not an abnormal state or a rampant variety of G. corallina (Ag.)." 3. Gigartina conferta (Schousb.), fronde cartilaginea, filiformi, vage ramosa, ramis fasciculatis confertis, ramulos abbreviatos patentes apice incrassato-ovoideos undique emittentibus. 4. Gigartina gaditana (Montag.), fronde cartilaginea, filiformi, di-chotoma, aculeis simplicibus brevissimis subsecundis utrinque attenuatis obsita. Probably closely allied to the Sphcerococcus armatus (Agardh). 5. Delesseria interrupta (Ag.), fronde membranacea tenerrima, in-terrupte costata, lineari, dichotoma, apice furcatarotundataque. This second number fully supports the high character which had been obtained by its predecessor, and we trust that the work will receive that support which it deserves from the botanists of Britain.
