2 A CATALOGUE OF THE BRITISH MARINE 



inspection of the list of their recorded stations. This is especially 

 the case with the Myxopliycea, the microscopic species, and those 

 which were formerly regarded as merely varieties of some other 

 species. 



With regard to the nomenclature, I have tried to bring it more 

 into accord with that adopted by all algologists on the Continent of 

 Europe and in the United States of America. I have introduced 

 very few changes on my own authority, and only those absolutely 

 demanded by the rules as to priority of publication. It may not 

 be out of place to call attention here to the careless way in which 

 the earlier authors quoted the works of their predecessors ; Good- 

 enough and Woodward, Turner and Stackhouse, for instance, refer 

 to the second edition of Hudson's Flora Anylica as if it were a 

 reprint of the one issued in 1762, which is very far from being the 

 case, many species making their first appearance in the edition of 

 1778 ; again, they refer constantly to Withering's Botanical Arrange- 

 ment, without stating to which of the three editions of that work, 

 which had then appeared, they refer ; on the other hand, Stack- 

 house's Nereis is treated as if none of it had appeared before 1801 

 (the date of the completed work), whereas in reality it was pub- 

 lished in three parts, which were respectively issued in 1795, 1797, 

 and 1801. Similar instances might be given to almost any extent. 

 Later authors followed the lead of the earlier ones, and now, when 

 date of publication is of such importance in matters of nomen- 

 clature, the practice has given rise to much confusion.
