Vol. VII. No. IV.

SOME LITTORAL DIATOMS OF JAPAN.

BY

K. OKAMURA, Zza£ua£usAhr.

Algologist to the Imperial Frsherzes Institute.

With Plates VIII—XIII.

The following list of diatoms was drawn up chiefly from the materials
collected by myself on the coast of Prov. Boshyu (near the entrance to
the Gulf of Tokyo) at Shirahama and Tateyama in several years mostly
during early summer and partly from those collected in many other
different localities in different seasons. They are for the most part
littoral diatoms excepting a few oceanic forms, and though there is
nothing new to contribute to the science, yet the work of this kind is
needed in this country where this branch of science is not much studied
as a speciality.

As there lies a great difficulty experienced by the workers in this part
of the world in getting access to the literature bearing on the subject, I
have given figures of all the enlisted species in the plates to illustrate
on one hand what I have observed and on the other to aid the students
in the work of identification. The references I have given under
each species in the list are only those I have been able to take into
consideration.
