Some few remarks are necessary in elucidation of these records. 



In the Irish Naturalist (vol. iv., p. 241) Prof. Johnson states that 

 " it would be comparatively easy for us to make a list of species found, 

 not recorded in Holmes and Batters' list. Such a proceeding would be 

 out of place, as there are many species in collections made by earlier 

 workers known to us not recorded." 



I cannot think but that the rendering of the Revised List of 

 Holmes and Batters more complete would be very useful to all those 

 who, like myself, are less acquainted with the collections of earlier 

 workers, and I am sure Prof. Johnson would earn the gratitude of 

 many workers by so doing. 



I shall have to refer to some of the omissions in the Revised List. 

 With regard to Codium adhcere^is, which appears in Holmes and 

 Batters' Revised List as unrecorded from Ireland, it will be found that 

 Harvey has added a note in his Phycologia Britannica to the effect 

 that it was first recorded for Ireland by Mr. D. Moore in 1834, who 

 found it on Rathlin Island, Antrim, and subsequently Mr. G. 

 Hyndman discovered it on Tory Island, so that the figures 10, 11, 12 

 should be added to the list. 



Codium tomentosum must also have a wider distribution than that 

 mentioned in the Revised List, for Harvey describes it as common on 

 the shores of the British Islands. That it is not new to Ireland is 

 obvious from the fact that Prof. Johnson refers in the "Irish 

 Naturalist" (vol. i.) to Strehlonema simplex (Crn.), an Epiphyte on
