corresponding antarctic formations. I have described above the Litlio- 

 ///j'/Z/zw-formation. Ikit this formation is Httoral as well as sublittoral, 

 and {M-obably much better developed in the tidal region; the Arctic 

 formation of CoraUi)iacciC is sublittoral. This is very remarkable — 

 the large shallow basins, of a bright rosa, then remind more of the 

 tropical than of northern littoral vegetation. The subantarctic shore 

 has the same character. It is uncertain, if we have got a form corres 

 ponding to the furmation of Fiicaccce: it is not impossible that one has 

 to consider the Urvillwa i^) sp. mentioned above as constituting a for- 

 mation of that kind, but I cannot settle the question now. 



My sublittoral formation of Desniarestia seems to me to correspond 

 pretty well to that of Laminariacece. — Owing to the loss of my collec- 

 tions I have not been able to say very much about the associations.
