British Moss-Flora. By R. BRAITHWAITE, M.D. Earn, xv. 

 Bryacea, Part II. This newly issued part of Dr. Braithwaite's most 

 valuable monograph treats of the mosses of the genera Pohlia (re- 

 placing Webera\ and Plagiobryum (replacing Zieria), and includes 

 25 species of the genus Bryum. As was to be looked for a few 

 changes are shown to be necessary in nomenclature. As the work 

 is indispensable to all students of mosses it would serve no useful 

 purpose to detail these changes. The plates are, as always, dis- 

 tinguished by their excellence.
