134 HowE: CHINESE MARINE ALGAE 
Peking, may well have been imported from Japan, as was recog- 
nized by Cotton, and should probably be excluded. 
A shorter list of Chinese seaweeds, published only a few 
months before Collins’ paper, was contributed by Major Th. 
Reinbold to Loesener’s Prodromus Tsingtauensis.* Excluding 
one doubtful determination, referred to below under Polysi- 
phonia japonica, this list includes 9 species, of which 4 appear to 
be additions to lists published before that date. Including 
these 4 species, 10 of the 11 species of Sargassum reported by 
Cotton, and the other species of Cotton’s enumeration that are 
not recognized in Collins’ approved list, and allowing for one 
duplication in the lists of Reinbold and Collins, we seem justified 
in stating that the number of Chinese algae known on the publi- | 
cation of Collins’ paper may conservatively be placed at 80. 
The small collections reported upon below were made by Mr. 
N. H. Cowdry, partly in the summer of 1919 in the vicinity of 
Pei-tai-ho, the locality from which came also the specimens stud- 
ied by Mr. Collins, and partly in the summer of 1920 at Chefoo. 
The specimens from Pei-tai-ho were forwarded for determination 
by Dr. Wm. R. Maxon, Associate Curator, Division of Plants of 
the U.S. National Museum, as was the case also with the speci- 
mens collected at the same place four years earlier by Mrs. Spen- 
cer Lewis. Later, Dr. Maxon sent a fluid-preserved specimen of 
Grateloupia that had been collected at Pei-tai-ho by Lieut. A. 
deC. Sowerby. Later, also, after the present writer had studied 
the Pei-tai-ho material submitted by Dr. Maxon, Mr. Cowdry 
himself brought his collection of Chinese algae to The New York 
Botanical Garden, most of the specimens with determinations 
provided by Professor K. Okamura of Tokyo, a list of whose 
determinations had been published by Mr. Cowdry at about the 
same time (Journal of the North China Branch of the Royal 
Asiatic Society 53: 180, 181. 1922). The present enumeration 
is then but an expansion and ina small way a revision of Cowdry’s 
previously published list. The number of species collected by 
Cowdry and now listed is 39, in addition to two named varieties 
and three species that are referred to genus only. Of the 39 
named species, 12 do not appear in lists previous to Cowdry’s 
and these 12 added to the 80 mentioned above bring the conser-
