Names preceded by f are now recorded for the North-east 

 of Ireland for the first time. Names preceded by * are first 

 records^ for Ireland. Perhaps the most interesting of all is 

 Halicystis ovalisj a green stalked alga, the size of a small 

 pin-head. This alga, though known to occur on the French 

 and Scandinavian coasts, has been only once before recorded 

 for Britain — from the Clyde district by the late Prof. Schmitz 

 and G. R. Murray, F.I..S.

* It should be stated that though the records are new, many of the 

 species have been already found by the writers at other points on the 

 Irish coast. 



- It was interesting to find a coralline off Carrickfergus, identical with 

 the much discussed Melobesia coinpressa, which M'Calla found in Dalkey 

 Sound.
