Note on the Genus Henrya. J find that American botanists 
(Asa Gray, Proc. Amer. Acad. xxi. 406; J. Donnell Smith, Bot. 
Gaz. xvi. 198, and J. N. Rose in litt.), are all in favor of restor- 
ing Henrya, Nees (Acanthacee) and they ought to know best; 
therefore my Henrya angustissima, in Journ. Linn. Soc. xxvi. 
111, and Hooker’s J/cones, t. 1971, must have a newname. I 
propose calling it Meohenrya angustissima.

Canadian Hepatice, named by W. H. Pearson, of Manchester, 
collected and distributed by John Macoun, 1891. 
This distribution completes the Bryophyta and includes 116 
specimens, accompanied by a printed list containing descriptions 
of two new species, with illustrations. It has been a great deal 
of work to get out these valuable sets of mosses and hepatics, and 
much credit is due for its accomplishment in so short a time. 
We are informed that a few remaining sets of the mosses will be 
sold at six dollars a hundred. E. G. B.
