Among a collection of mosses made in 1874-75 by S. Berggren 
(now in the Museum of the University of Lund) I found specimens 
of both the New Zealand species of this genus, and in a condition to 
throw fresh light on the peristome charact 
In P. Buchanani the teeth are erect, strict and linear-subulate, 
not broadened at base, 180» long, densely and highly but finely

at once from P. austro-georgicum Car 
n Berggren’s specimens of P. Brother ee (Kelly’s Hill, South 
i. 1874, No. 2426; and Porter’s Pass, Sout 1874, No. 2495), the 
peristome is somewhat worn, but it shows ihe ah deep orange red,

the short, turgid capsule.

A very distinet little species, with no near allies at least in the 
Australasian region. Only a single capsule was found, so that the 
above description of _— Sratinons may pti some slight modification, 
but there is every reason to suppose it normal.
