Notwithstanding that the peristome of this moss consists of 
eight teeth only,—at least in the perfect specimens which I pos- 
sess,—and these as entire as the teeth of Oclollepharum serra- 
tum,—yet the plant has so completely the habit of a Splachnum, 
and “especially of S. angustatum, that I cannot bring myself to 
separate it from that genus. Should 
found to havea calyptes resembling that of sebagai o serra- 
tum, it might fairly be ranked with that species, under the name 
of Orihodon, which Mr. Brown has established with excellent 
characters, in the 12th volume of the Transactions of the Lin- 
heean Society. That gentleman has noticed, what I omitted to 
observe in O. serratum, the three longitudinal lines visible in 
each tooth of the peristome, as is seen in t is chnum,—indi- 
cating, as Mr. Brown observes, the coalescence of four teet
