 A few years ago I picked up on the sea-shore near Berwick, a 

 single specimen of a Dasya which appeared to be specifically 

 distinct from any of the British Dasya. Mr Holmes, to whom I 

 sent the specimen, believed it was identical with Harvey's Dasya 

 Gibbesii, and under that name I recorded its discovery in the 

 tenth volume of the Proceedings of the Berwickshire Naturalists' 

 Club. Since then, Mr Holmes has had an opportunity of com- 

 paring the plant with authentic specimens of Dasya Gibbesii and 

 has come to the conclusion that it is not identical with them, but 

 should be referred to Dasya Mueller?', Sond. (Harv. Phyc. Austr., 

 pi. 31.) Whatever it may turn out to be, the plant is probably 

 a waif brought to our shores by some ocean current, and is not 

 entitled to be considered a native. 



Family — C orallinaceee.
