;^., Mr. Macmillan remarked, *' In the above list of the most conspi- 

 cuous Lichens of these islands, it will be observed that several species 

 occur which are usually found only in the depths of shady woods, in 

 situations far inland. The Parmelia glomulifera, Sticta scrobiculata, 

 Placodium plumbeum, Nephronta resupinata, and Sticta fuliginosa^ 

 are almost peculiar to the extensive forests of mountainous regions 

 where there is a great deal of moisture and shade ; and hence their 

 occurrence, not merely as stray or isolated individuals, for the Lichens 

 are sometimes very erratic in their choice of habitats, but in con- 

 siderable quantities on islands almost entirely destitute of wood and 

 very much exposed, is a somewhat singular circumstance. It is also 

 curious to notice in the list no less than eight species, which we 

 should scarcely expect beforehand to find, insomuch as they belong
