﻿446 BOTANICAL GAZETTE [june 



the whole consUtutes a unique publication of great value. Professor Miyab6 

 considers the outer and inner morphology, propagation, distribution, economic 

 uses, pathology, and classification of the kelps, and describes several new 

 species — eight in Laminaria, three in Alaria, one in Undaria with Dr. Oka- 

 mura, and establishes a new genus, Kjellmanniella, evidently not very far from 

 Pleurophycus of Setchell and Saunders. Of this two species and one variety 

 are described. The longest of the three articles is the one by Mr, Yanagawa, 

 in which he describes the kelp beds from an economic point of view and dis- 

 cusses the collections, seasons, tools, methods, boats and co-operative agree- 

 ment among the fishermen. Statistics are given concerning the history of the 

 industry, its total value for the last thirty years, the average annual harvest, 

 the profits of the fishermen, etc. Methods of curing the kelp, prices, gov- 

 ernment supervision, and a number of other matters of interest are considered, 

 and the trade varieties of kelp are named and described. Professor Kintaro 

 Oshima supplies a brief paper, giving the methods and results of chemical 

 analyses and some notes on organic compounds peculiar to the kelps. The 

 plates are handsome lithographs, quarto size, setting forth the habit of new 

 and important species, figuring the anatomy, and affording views of fishing 

 scenes, tools, warehouses, bales of seaweed and beds of kelp. — Conway
