Macounii, Kindberg, may be noted. Orthotrichum lonchothecium 
also should be, for it is antedated by O. stenocarpum, Venturi. 
Many changes from the distributed names of the Canadian 
Mosses have been made. Those who have not mounted their 
specimens are better off than those who have. The most serious 
criticisms which can be made of Prof. Kindberg’s work are these : 
A too evident desire to name new species without sufficient com- 
parison with American material, though some good work has 
been done by careful comparison with European specimens ; 
second, unsystematic, and often meager descriptions, too fre- 
quently from sterile specimens; third, a lax system of nomen- 
clature by which species and varieties previously described and 
published, or distributed, are given new names. Examples of 
this will be found on the species numbered 199, 245, 259, 284, 
296, 749, 799, 811, 818 and 939. We hope, as our Western 
mosses come to be studied, that Prof. Macoun will continue the 
same generous policy that he has with our Eastern ones, and give 
students the benefit of comparison with the fine collections which 
he has gathered together for the ‘‘ Geological and Natural His- 
tory Survey of Canada.” E. G. B.

It is pointed out that the name Blepharipappus, Hook. (1833), 
antedates Layza, H. & A. (1841), and the species included by 
Dr. Gray in Layza are transferred to the older genus ; Ptilonella, 
Nutt., based on Blepharipappus scaber, Benth., is maintained as 4 
genus. Lreminula is the generic name proposed for Dimeresia, 
A. Gray (1866), Prof. Greene regarding Dimeresa, Labill. (1824), 
as the same word as Dimeresia.

Professor Bailey maintains that there are two, and perhaps 
three, species included in the description of P. pumila in recent 
text-books. P. pumila, L., he regards as of northern distribution, 
growing on sandy and rocky shores, and characterizes it 46
