This list contains 153 species ; probably more occur on the is- 

 lands, which would require another and a longer visit in spring to 

 make an exhaustive catalogue of their plants. There are, at any 

 rate, four or five plants whose names do not appear in my note- 

 book that it is hard to believe are absent. The chief interest in this 

 list, in addition to the occurrence of some rarities mentioned in the 

 body of this report, is the presence of a good proportion of plants 

 belonging to Watson's Atlantic type. Of these, we have Hyperi- 

 cum elodes, Er odium maritimum, Sedum anglicum, Cotyledon umbili- 

 cus, Crithmum maritimum. Inula crithmoides, Euphorbia par alias, and 

 Scirpus savii. If we look to the flora of Tory Island, as reported 

 upon in the '* Journal of Botany," 1879, by my friend Mr. Barring- 

 ton, we shall find but two members of this group. This island lies at 

 the opposite corner, on the north-west of Ireland, and is more than 

 double the area of those under consideration. Its flora is scantier 

 by about ten species, and of much less interest ; but the comparison 

 well shows the failure of this type as we travel northwards, in 

 spite of the more western and Atlantic situation of the larger 

 island.
