Agardhii, Gom., on Polysiphonia nigrescens (Margate) ; L. Rivulari- 

 anew, Gom., in sheaths of Microcoleus chthonoplastes (Studland and 

 Swanage) ; Phormidhtm coriit//i, Gom., in crevices of rocks near 

 high-water mark (Swanage) ; Erythrotrichia Boryana, Berthold 

 (Eastbourne) ; Colaconema chylodadice, n. sp., in Chylocladia ovalis 

 (Torquay and Plymouth) ; C. ? reticulatum, n. sp., on Desmarestia 

 Dudresnayis (Moville); Chantransia ccespitosa, on Codium tomentosum, 

 fuciy etc. (Swanage) ; C. mirabilis, on Desmarestia aculeata (Swan- 

 age) ; Rhodochorton pattens, Hauck. (Seaton, Devonshire, with 

 tetraspores in July) ; Callithamnion lepadicola, J. Ag., on limpet 

 shells (Swanage) ; Bonnemaisonia hamifera, Hariot (Falmouth) ; 

 Rhododisats pulcherrimus, Crn., on an old Solen shell (Plymouth) ; 

 Peyssonnelia (Cruoriettd) rubra, J. Ag. the examples from Birturbui 

 Bay, described by Harvey as P. Dubyi, prove to be P. rubra ; P. 

 atropurpurea, Crn. (Penzance) ; Criteria rosea, Crn., on old shells 

 (Plymouth). 



It is further noticed that Professor J. G. Agardh, in his recent 

 " Analecta Algologica," continuatio ii., records three new species of 

 Ceramium, viz. C. Crouanianum, C. fruticulosum, and C. arborescens, 

 from Britain (probably from materials sent to him from Devonshire 

 or Cornwall by Mrs. Griffiths), and raises to specific rank vimtneum, 

 corymbosum, and botryocarpum, formerly ranked as varieties of C 

 rubrum. 



A new genus is established for the plant formerly known as 

 Spermothamnion Turneri, f. intricata (Holmes and Batters' " Revised 

 List ") ; the discovery of its tetraspores (by Mr. G. Brebner, in 

 October 1895, a ^ Plymouth) having shown it to be generically 

 distinct from all known Ceramiece. The name selected is in honour 

 of Mr. G. W. Traill. 



Trailltella, n. g. Fronds of monosiphonous branching jointed 

 filaments ; the primary filaments procumbent and attached to sub- 

 stratum by disc-shaped cells the secondary arising from the primary 

 and erect and branching. Tetraspores immersed, irregularly cruciate, 

 formed from a portion of contents of cells in the continuity of the 

 filaments (formed like monospores of Rhodochcete, see Bornet in " Les 

 Algues de P. K. A. Schousboe," p. 361). Cystocarps and antheridia 

 unknown. 



The "Journal of Botany" has been enlarged from 32 to 

 48 pages per month, and its price is now i6s. instead of 125. per 

 annum. The enlargement has been rendered necessary by the 

 pressure of matter waiting for space. The decease of Grevilka has 

 added to the papers on Cryptogams forwarded to the " Journal of 

 Botany." 



British Hieraeia. The Revs. W. R. and E. F. Linton propose 

 to issue a set of specimens to illustrate the numerous forms of this 

 most perplexing genus that have been in recent years detected within
