1919] Collins,— Chinese Marine Algae 205 
A general list of the marine algae of China, to include all that seem 
sufficiently authenticated to the writer from these four sources, is 
quite meager for so long a coast, and especially in contrast with our 
knowledge of the flora of Japan. For the latter we have, in addition 
to a number of papers by European authors, many publications of 
recent years by Japanese phycologists, Yendo, Okamura, and others. 
The Icones of Japanese Algae, of which the fourth volume is now being 
issued by Okamura, is an illustrated work of the first rank, and is 
indispensable to any student of North Pacific algae. In this list, as 
given below, the important genus Sargassum is omitted; even more 
than with other genera it is impracticable to assimilate the different 
records. In Agardh's monograph! localities are given vaguely, as 
“Mari Japonico et Chinensi.” Grunow's posthumous notes? 
would probably give the needed information, but having been issued 
during the late war, are not accessible in this country. Abbreviations 
used in the list for Chinese localities are, C, Cheefoo.? H, Hongkong. 
P, Pei-tai-ho. S, Swatow. W, Wei-hai-wei. To show relationships, 
à note on the further distribution of each species is added.

3 The different forms used for the same Chinese name present some difficulty, but it is as- 
sumed that Cheefoo, Tschifu and Tché-fou, refer to the same place.
