BOTANY OF KERGUELEN ISLAND. 
to the bay, 10 or 12 species would most likely have been added to the 53 in his 
collection. Judging from the number of species apparently indigenous to un- 
sheltered situations which go to foi’m the 18 that arc not represented in his collec- 
tion, this conjecture may have been not far from the mark. 
But the advantages of situation afforded in Swain’s Bay for the growth of 
various Algae absent from the almost wav'cless shores of Observation Bay woidd 
have availed nothing, had it not heen for the liberality and kindness of Captain 
Fairfax, ll.N., in command of II.M.S. “ Volage.” Ilaving invited Mr. Eaton to be 
his guest for three weeks, he conveyed him in his gig to almost every part of 
the bay that wms accessible by boat in Kerguelen Island w'eather, and sm-rendered 
his cabins without reservation to the reception of buckets and specimens of all 
descriptions, excluding only seals and cetacea accommodated elsewhere. 
The local distribution of the S 2 iecies round the coast may be ascertained roughly 
from a comparison of the constituents of the collections above mentioned. Of the 
71 sjjccics, II are common to all of the collections, and 8 common to three out of 
the four, making together 22 species, which may be regarded as plants generally 
distributed round the island ; 14 are common to Mr. Eaton’s collection and one of 
the other three, and 1 species to Dr. Hooker’s and Dr. Kidder’s, — together making 
15 local plants, mostly of frequent occurrence ; 5 are common to Dr. Hooker’s 
collection and Mr. Moseley’s (gathered in Christmas Harbour), and 29 are in one 
of the collections only, making 34 scarce or rare species. Of the 29, there are in 
Dr. Hooker’s collection 7 species, in Mr. Moseley’s 4, in Dr. Kidder’s 1, and in 
IMr. Eaton’s 17. 
As to their general geographical range, 20, or rather more than a quarter of 
them, are found in various parts of the shores of Em-ope, and some are cosmopoli- 
tan. The following 8, so far as is knowm, are peculiar to the island : — Besmarestia 
clwrdcdls, Sphacelaria corymbosa and S. affinis, Melobesia kerguelena, Nitophyllum 
fusco-rubrum, Epymenia variolosa, Ptilota Eatoni, and Callithamnion simile. 
The following are the numbers of the species after their respective families : —
