southern seas. The confusion that had thus arisen with regard 

 to specific names was much lessened hy the appearance of 

 Hooker's "Handbook of the New Zealand Flora" in 1864. 

 The number of brown seaweeds there described is fifty-eight. 

 Almost nothing was done after the publication of this standard 

 work in the way of arranging and classifying the New Zealand 

 Alga-, until Dr. Berggren of Lund University made a collection 

 in 1876. His specimens were examined by J. S. Agardh, who 

 published a revised catalogue of New Zealand marine Alga;, 

 reducing the number of Fucoidece to fifty-two. Many of the 

 specific names of Hooker were altered, and a few species were 

 united and others cast out. It is, therefore, very difficult for me 

 in many cases to determine the true specific name with certainty, 

 especially as I can only refer to the works of a few of the elder 

 algologists. Therefore, in the following paper, where the name 

 is doubtful I have given it both, as it is in Hooker's Handbook 

 and Agardh's Catalogue. In the " Transactions of the New 

 Zealand Institute " for 1879 there appeared a list of the seaweeds 

 of Canterbury, but as it was evidently only a compilation from 

 Hooker, I will not refer to it further. 



The following is a list of the Fucoidece that have as yet been 

 found at Banks Peninsula : —
