A MONTH ON THE SHORES OF MONTEREY BAY. 67 
cens, Adenocystis Californica, Callithamnion Americanum, 
and Bonnemaisonia hamifera, are perhaps deserving of 
special mention, inasmuch as they do not appear in Dr. 
Anderson’s “List of California Marine Alge.” Bonnemat- 
sonia hamifera is a beautiful and noteworthy alga. Prof. 
Farlow states (in a letter to Dr. Anderson) that it has also 
been found at Santa Barbara, but that the plant from which 
the description was drawn came, somewhat recently, from 
the coast of Japan. 
The month’s work about the Bay of Monterey was rewarded 
by the acquisition of specimens representing about 105 
species, some of which are due to the generosity of others 
who were collecting at the same time. 
For assistance in the 
determination of some of the specimens I am indebted to 
Dr. C. L. Anderson of Santa Cruz and Prof. W. G. Farlow of 
Harvard University. 
Below is a list of the plants collected, 
with the exception of a few sterile fragments, the affinities of 
which are still uncertain:
