Algse- 



(By Mrs. E. S. Gepp.) 



Marine Algology.* — A. Mazza publishes the first instalment of his 

 notes on marine algse, intended by him to assist and encourage the 

 amateur collector. He does not aim at superseding the well-known 

 handbooks, and rightly refers to De Toni's Sylloge Algarum as indis- 

 pensable to all systematists and collectors, but for the benefit of the 

 uninitiated he embodies his own observations in the form of notes on 

 each of the more common species. He begins with Bangiacese and 

 deals with four genera including 12 species. The beginning only of 

 Chantransia is given in this part. After the remarks on each species, 

 references are given to specimens of which the geographical distribution 

 is mentioned. The usefulness of such a work as this is self-evident. 



South Orkney Marine Algse.f — Two short papers on algse from 

 these islands appear together, one by A. and E. S. Gepp, and the other 

 by E. M. Holmes. The former is an account of some material sent to 

 the authors after the publication of their previous paper. It includes 

 one new species, Hydrolapathum stephanocarpum, closely allied to 

 H. sanguineum ; and describes and figures two other algse which are 

 sterile and doubtful. The Leptosarca simplex of their former paper is 

 transferred to Gracilaria on the strength of the tetraspores which are 

 found in the material of this last consignment. The paper by E. M. 

 Holmes includes records of four calcareous algse, two of which have been 

 described as new forms by M. Foslie in a previous publication. Frag- 

 ments of six species on non-calcareous algse were found adhering to the 

 corallines, and are included in this paper.
