2 7 Additional Remarks 



to » Marine Algal Coniniutiitics of the Juan i^'ernandez Islands» (Nr. 23). 



By 

 C. SKOTTSBERG. 



In my paper on the conimunities formed by Marine Algae in the Juan 

 Fernandez Islands the Coralline algae were quoted as Corallina sp., LithotJiam- 

 7i?on (or LitliophyUuni), and Litjiophyllum fernandezianum. The collection was 

 in the hands of Mme Palu. Lemoine (comp. Levring, Nr. 25 of this publica- 

 tion, p. 753) and my efforts to get into contact with her had proved fruitless. 

 Finally, the Foreign Office in Stockholm kindly undertook, through the Swedish 

 Consulate General in Paris, to make a search for the collection which, in spite 

 of the absence of Mme Lemoine, who is reported to have joined the fugitives 

 from the capital, was found in the Laboratoire de Cryptogamie, taken care of 

 and returned to me in perfect condition. I am greatly indebted to Mr. S. 

 Grafstrom of the Foreign Office, and to Consul General R. NORDLTNG in Paris 

 for their kind assistance. 



The collection was handed over to Dr. T. Levring, who promptly under- 

 took to identify the species, thus enabling me to make the following important 

 additions and corrections to my paper. 



P. 673. St. 36 b, Lower littoral: Coraliiua cJiileiisis and Cnvieri. — St. 39 a 2, 

 and St. 2, in pools: iarallhia Cnvieri: Litlwphyllinit pnsliilaiiini (on Padiria). 



P. 674. St. 39 b and St. 3, Lower littoral: Corallina Ciifieri 2Lnd Litliophyllum 

 pustulatnni (on Padiiui). 



P. 675. St- 8. Bottom layer, on stones: Lithophylluin Ass. of Z. benundense 

 (small, warty crusts) and L. discoideum (very large, smooth clumps). — St. 4. 

 LithothaiiDiiuvi Ass. of L. validum and Litliophyllum herniudcnse. — St. 13, 

 Sublittoral: Corallina Ciwien. — St. 6, Sublittoral: Lithothainninm validum. 



P. 6']6. St. 5. Ass. of Lithothamnion validum. — St. 11. Litliophyllum 

 pustidatnui (on Padina). — St. 7. On a large stone, thin crusts of Litliophyllum 

 de dpi ens. 



P. 680. Associations and Formations. The leading species of 

 crustaceous Corallines seem to be Lithothamnium validum and Litliophyllum 

 discoideum, which form a deep-water association on stones, pebbles and old 

 shells which become thickly encrusted. With these is also Litliophyllum bermu- 

 dense. The other association of the »Formation of Crustaceous Corallines* is 

 501—41438.
