1. Dasya coccinea, Arjardh. 



Hab. In the sea, frequent. Annual. Summer and autumn. 

 In England, Mrs. Griffiths, Professor Walker Arnott ; in 

 Ireland, Miss Hutchins ; in Bute and Frith of Forth, Dr. 

 Greville ; said to be rather rare in Scotland, but we do not 

 think so. It is not equally abundant at every season ; but 

 is generally frequent during summer and early autumn 

 about Ardrossan, Troon, Ayr, Ballantrae, Portpatrick, in 

 the island of Arran, island of Cumbrae, and at Southend, 

 Kin tyre. 



The most beautiful specimens I ever saw were from Bal- 

 lantrae. It is thought to be annual. I question this, 

 having often got it in winter. I found it on the 22nd of 

 last December, full size, covered with Crisia denticulcLtay 

 and just coming into fruit, some of the red-tipped sticliidia 

 having the granules quite formed. It is one of the most 

 beautiful of our Alga?, on account of its fine crimson colour 

 and feathery form. It is found here occasionally in its 

 young state, in which at one time it was called Ceramium 

 patens. 



There are very fine figures of it in Dillwyn's ' British 

 Conferva?,' PI. xxxvi. He says, " Few marine productions 

 exceed the prcs^cnt species in beauty or frequent occurrence.
