34 TRANSACTIONS OF THE [Sess. lxxvi. 



Borgesen's methods of nomenclature will be seen from 

 the following (p. 711): — 



Of the formations of exposed coasts (littoral region), he 

 recognises among; others a Hildenbrantia formation con- 

 sisting of Hildenbrantia rosea, Ralfsia verrucosa, and 

 blue-green Algae ; a chlorophyceae formation consisting of 

 Prasiola crista, Enteromorpha intestinalis, and Rhizo- 

 clonium riparium ; and a porphyra association found 

 under the chlorophycese formation, and consisting of 

 Porphyra umbilicalis. 



It will be recognised that, according to the preceding 

 matter and suggestions, the terminology would be as 

 under : — 



The littoral region of exposed coasts being part of the 

 general halo-nereid sub-formation, consists of, among 

 others, a Hildenbrantia association composed of small or 

 large plant societies of Hildenbrantia rosea, Ralfsia 

 verrucosa, and blue-green Algae ; a chlorophyceae associa- 

 tion consisting of plant societies of Prasiola crispa, 

 Enteromorpha intestinalis, and Rhizoclonium riparium ; 

 and, existing beneath the chlorophyceae association as a 

 lower storey, a plant society of Porphyra umbilicalis. 



The following summarised notes may illustrate further 

 the suggested method of treatment. 



These brief notes are from observations made by the 

 writer on the marine Algae of the Kirkcaldy district of 

 Fife (littoral region). 



Nereid formation of Algae ; marine (halo-nereid) sub- 

 formation ; littoral region. 



District I. — Ravenscraig to Craig Endle ; rocks and 

 sandy beach ; creeks and isolated rocks. 



Alg^e. — (1) Fucaceae association, with Fucus vesiculosus 

 {minus bladders) dominant between H. and L.W.M. 



(2) Plant societies of — 



(a) Gallithamnion scopulorum. — Extensive, exist- 



ing beneath F. vesiculosus as a lower storey. 



(b) Enteromorpha compressa. — Not plentiful, on 



rocks both at H. and L.W.M. 



(c) Porphyra laciniata, — Fairly plentiful at L.W.M. 

 District II. — Craig Endle to Dysart harbour ; A, a series 



of creeks ; B, a bay with rock areas.
