A distinct species, quite common on the north-western coast 

 of Europe. It is interesting to find this species within our 

 boundary.

The present species seems to have been taken as Bryopsis 

 plumosa by various collectors. The mode of ramification, 

 however, approaches more to B. cupressoides Lamx. than the 

 other members of the genns. The lateral branches, and ramu- 

 lets on them, are all very much elongated and slender so that 

 the conical outline of a frond, characteristic of B. cupressoides, 

 is quite disturbed.
