This interesting little moss adds a fourth species to the subgenus //olo- 
dontium, a small group of Dicranum hitherto consisting of three species only, 
which in some respects form a connecting link between Micranoweisia and 
Dicranum. The three remaining species were described by Mitten in the 
‘ Musei. Austro-Americani’?: one (D. inerme) from Andes Quitenses, leg. 
Jameson ; the other two (D. ramulosum, Mitt., and D. pumilum, Mitt.) from 
Hermite I., Fuegia, leg. J. D. Hooker. J). inerme is a quite different plant, 
with a seta 2 in. long, ete. I have not seen specimens of the other two plants, 
but they clearly differ from the New Zealand species : D. ramulosum in the 
shorter stems, leaves erecto-patent, striate, with different upper areolation : 
and D. pumilum in the longer seta, which Mitten describes as ** pedunculo 
elongato," while that of D. ramulosum, which is 2 lines (=5 mm.) long,'is 
described as “ breviusculo.? 
The two species of the newly deseribed genus 
Verrucidens, Card., placed by Brotherus under the tribe Seligeriæ, must also 
be compared : V. turpis differing notably in the papillose cells and prominent 
dorsal lamellae of. the lower part of the peristome teeth, and V. immersus in 
the immersed capsule. Our species would appear to show, in the peristome, а 
relationship between Verrucidens and Holodontium. In the habit and somewhat 
peculiar torsion of the upper part of the leaf when dry, while the lower half 
is erect and unaltered, it exhibits a resemblance to /icranoweisia antarctica 
(С. Muell.). Weisia Меры, В. Brown ter., has smaller. regularly quadrate, 
often roughish upper cells, smaller auricles, ete.

The Campylopi of this group are very difficult to determine: partly 
because of the uncertainty which attaches to the value of slight differences in
