This species agrees well enough in habit and character with some _ 
of the exotic species of Cyrtopus, e.g. C. acuminatus, Hook. Muse. 
Exot. t.151, and I therefore place it along with them rather than in 
Anomodon or Antitrichia, both of which genera have been founded 
on incorrect views of the structure of the inner peristome. The cilia 
neither spring from the sides of the teeth, as stated in ‘ Muscologia 
Britannica,’ nor are they opposite to the teeth, as Bridel says ; on the 
contrary, they are (as in all mosses) a continuation of the sporular sac, — 
and they alternate with the teeth. They are the most slender and 
delicate I have seen in any moss, and consist either of a single series 
of cellules throughout, or here and there of a double series, when 
they are often perforated. ‘There are sometimes rudimentary ciliola 
(solitary or twin) between them.
