 almost fully developed thallom in the middle of May.

A sublitoral alga, most frequent and best developed on 

 stony or shingly bottom within the npper part of the zono, on 

 ^ depth of 3—10 fathoms. But it also descends to a grea- 

 ter depth, and somotimes even to the lower limit of the nOi- 

 ^ed zone. It is a pelagic plant which prefers open shore, 

 ■ but also occurs on sheltered places and even enters the inner 

 part of the great bays. Here it assnmes, however, forms 

 lu general habit mnch diifering from the pelagic andtypical
