at Lyall's Bay, Napier, Tauranga, Hokianga, Bay of Islands, 

 but it seems to me to be distinctly a northern form. I have 

 no specimens from the South Island, and found it increase itr 

 abundance from Wellington to Auckland in the North Island. 

 In the Eangitoto Channel in January I found it to be the 

 most abundant of all the Fucacece.

This is one of the rarest of our FucacecR. I have other 

 species of Sargassum, from Stewart Island and the Bay of 

 Islands ; but, as this is one of the most difficult of all the 

 genera of the Algcs, I hesitate identifying them without 

 abundance of material.
