204 PROF. G. DICKIE ON ALGJE FOUND AT KERGUELEN LAND. 



Iu conclusion, excluding Prasiola Sauteri, which is a freshwater 

 species, the Marine Algae collected by Mr. Eaton are 52 in num- 

 ber ; adding to these other 13 mentioned in the Antarctic Flora, 

 the marine Algae of Kerguelen are 65 ; they are included under 

 the following families : 



Fucaceae, 2. Sphaerococcoideae, 7. 



Sporochnaceae, 4. G-elidiaceae, 1. 



Laminariaceae, 2. Rhodymeniaceae, 4. 



Dictyotacese, 2. Cryptonemiaceae, 8. 



Chordariaceae, 3. Ceramiaceae, 6. 



Ectocarpaceae, 3. Siphonaceae, 3. 



• Hhodomelaceae, 4. Ulvaceae, 5. 



Laurenciaceae, 1. Confervacese, 7. 



Corallinaceae, 3. 



Of these, 16 belong to the olive, 34 to the red, and 15 to the 

 green series. 



Nine, so far as is known, are peculiar to the island, viz. Des- 

 marestia cJiordalis, Sphacelaria corymbosa, 8. affinis, Jfelobesia Jeer- 

 guelena, NitopTiyllimfmco-rubrum, Plocamium Hookeri, Epymenia 

 variolosa, Ptilota Eatoni, CallitJiamnion simile. 



Twenty-one, or nearly one third, are also found on various parts 

 of the shores of Europe. 



Postscript. 



In the Bulletin of the United-States National Museum there 

 is a summary of the Algae collected during the Transit Expedition 

 to Kerguelen : the species were examined by Professor Farlow, and 

 are 22 in number. Of these, three are not in Mr. Eaton's very 

 complete collection ; I quote from Professor Farlow's notes. 



"Sphacelaria funicularis, Mont.? 



li Quite a number of specimens too small for accurate determi- 

 nation probably belong to this species. 



u Rhodomela Gaimardi, Mont. 



M A single specimen of this was collected by Dr. Kidder. This 

 species is new to Kerguelen, the nearest recorded station being 

 the Auckland Islands.

"Callithamnion Ptilota, H. fy H. 



" New to Kerguelen, previously recorded at Crozet Islands." 

 The Marine Algae of this island are therefore, so far as known, 

 about 70 species.
