COLLECTED IN KEBGUELEN LAND. 181 



in Herb. Kew. any specimens of several of Dr. Taylor's critical 

 species. These may probably be found in his herbarium, which I 

 understand is now in Boston, TJ. S.; and perhaps on further search 

 one or two may still turn up at, Kew. The present valuable and 

 comparatively large collection was made by Mr. Eaton at intervals 

 from December 1874 to February 1875, at the three stations in the 

 island which were visited by the Expedition. These were Royal 

 Sound and Observatory Bay on the S.E., and Swain's Bay on the 

 S. "W*., all three, as it would appear, possessing very much the same 

 lichen-flora. Though several of the species bear at first sight a 

 general resemblance to some of our northern lichens, yet on ana- 

 lysis they are found to be quite distinct, and for the most part are 

 quite peculiar to this island. Most of the novelties amongst them 

 have been briefly recorded by me in ' Journ. Bot. ' for November 

 1875 and January 1876 ; and I here give their fuller diagnosis, 

 with which Dr. Nylander, w r ho most kindly assisted me in their 

 determination, has favoured me.
