TWO NEW BRITISH MAUINTE ALG.E. 41 



Mr. Sawers further remarks that '^^the exploration of Loughs Foyle and 

 Swilly, in the north of Ireland^ is adding new localities for a number of the 

 rarer Algae. Of those already obtained, there may be enumerated Taonia 

 atomaria, Haliseris jwlypodioides, Stilophora rliyzodes, Arthwcladia villosa, 

 Sporochnus ptdunculatus, Bonnemaisonia a.iparatjoides, Ginnania furcellata, 

 Gloiosiphonia capillariSf Gigartina acicularis, Kalymenia Dubyi, K. 

 renifovmis." 



Having received from Mr. Sawers some very important additions to our 

 collection of Marine Algae, besides specimens of the new Sea weed, we were 

 struck with the number of, hitherto, southern species among them. We trust 

 that the zealous labours of two such ardent Algologists as Messrs. Sawers, and 

 C. Morrison, may yet bring out new localities for many of our rare Algae, for 

 the gi'owth of which the sheltered Loughs of the north of Ireland would 

 appear to offer many facilities. The subject of this notice, to our eye, looks 

 very unlike any Desmarestia with which we are acquainted, and we should 

 much rejoice were Mr. Sawers' designation yet applied to it. 



Striaria fragilis. 



Wo have to announce the occurrence in Scotland of another southern 

 species, also new to Britain; and Dr. Landsborough has kindly favoured us 

 with the following notice of it. Striaria attenuata is the only other British 

 species, and that we believe has only occurred on the north and south coasts 

 of Devon and Cornwall, and on the coasts of Connemara: — 



"It is encouraging to learn that Algao are from time to. time occurring 

 that had not previously been known as British. Striaria fragilis is one of 

 these. It was dredged in Lamlash Bay, Isle of Arran, in August, 1853. 

 The party consisted of Professor Walker Arnott; the Rev. Mr. Miles, of 

 Glasgow; Mr, Campbell, of Glasgow; and myself. A considerable quantity of 

 it came up in the dredge, but little of it was secured, as it did not strike 

 us as new. Professor W. Arnott was not in the boat at the time, but when 

 it was shewn to him, he ascertained that it was Striaria fragilis, having a 

 named specimen, which he had received from M. J. Aghard. When I re- 

 turned home, I found that I had a good specimen, which I had dredged 

 in the same locality in the summer of 1851. It bears some resemblance to 

 an overgrown specimen of Stilophora Lynghycei, dredged along with it. On 

 learning that it was new to Britain, the same party went back about a month 

 afterwards to lay in a store, but we got not a specimen worth preserving. 

 I am sure, however, that it is abundant in that locality." 



We congratulate not only the discoverers of these new species, but also Algo- 

 logists in general, that they have fallen into liberal hands; they will not be 

 hoarded up, but put out, we trust, to good interest; for liberality in the ex- 

 change of specimens cannot fail to induce a corresponding feeling in the 

 recipients; both our friends deserve largely in this respect.
