as some British students may not have access to the pages of the 
Revue wombat I translate the remarks in which he sums up some 
of the characters which separate the new species from some of its

closely related to typical B. arcticum, but which hag the inner 
layers of the outer peristome simple and regular (i.e. without 
cloisons accessoires’); such, ~ Behe is the ea found in 
Kongsvold by M. Kindberg, which I have named B . Kindbergit ; 
another, gathered in the Mele “of Aland by M. Bomansson, is 
remarkable for the globular sporangium of the capsule, abruptly 
contracted into a long narrow neck. But in these forms with 
regular peristome teeth, almost all the other ahinvactsns shai the 
same as in the forms with ‘ cloisons accessoires’; the leaves are as 
arrowly acuminate and distinctly margined; the nerve longly

of B. areticum. e Bryum fro n Lawers is at once separated

and especially the Scandinavian shea very carefully, is of opinion 
hat B. Lawersianum does not belong to the “ arcticun' ’ group of 
species, but to the “pallens” group. “He holds it to be nearly 
allied to B. Lindbergit sere a plant which I baie. oe seen, and
