Okamura, K., Icones of Japanese Algae. (Vol. I, No. 

 1. (PI. I-V.) May, 1907. Tokyo. Price 2.50 Mk.) 

 The author publishes the present " Icones " by himself. 

 It may be taken as the continuation of his former work 

 entitled "Illustrations of the Marine Algae of Japan," which 

 had to be discontinued after the issue of only 6 numbers (PI. 

 I-XXX). In the present number the following 8 pecies are 

 descibed : Micvocladia elegans n. sp., Microcladia corallinae 

 (Mart.) Okam., Carpoblepharis Schmitziana (Rbd.) Okam., 

 Scinaia furcellata (Turn.) Biy., Chondria crassicaulis Hary., 

 Zonaria Diesingiana J. Ag., Hydroclathrus cancellatus Bory, 

 Cylindrocarpus rugosa Okam. 



Descriptions are given both in English and Japanese, and 

 especially for those plants which are either new or little known 

 among the foreign algologists cares are taken to describe them 

 with English in detail. Propagative organs of Chondria cras- 

 sicaulis Hary. which the author promised to illustrate in a 

 certain number of his " Illustrations of the Mar. Algae of 

 Japan " are pictured here. K. Okamura.
