Entopon Macounm C. Muell. & Kindb. in Macoun, Cat. Can. Pl. 
097. 1809. 
Authentic specimens from type locality in Herb. Macoun are 
not referable to Eyétodon at all, but are one of the complanate- 
foliate Hypneae. Capsules are needed to classify them. There 
are no quadrate alar cells and the cells at the angles are so little 
enlarged as to be scarcely noticeable. 
ENTODON (?) EXPALLENS C. Muell. & Kindb. in Macoun, Cat. Can. 
Pl.6:177. 1892. 
This species belongs to the same group as Z. Macounit. 
ENTODON suBFLACEUS C. Muell. & Kindb. Can. Rec. Sci. 1894: 
ot, 
I have been unable to examine any specimens of this species, 
as Prof. Macoun has none in his herbarium. 
CYLINDROTHECIUM FLorIpANuM Duby, Regensb. Flora, 58: 284, 
is probably not related to Entodon, as the horizontal capsules 
described are not in accordance with the characters of the genus. 
We have not been able to obtain a specimen of it, as the type 
cannot be found in the Duby nor the Boissier herbaria at Geneva. 
2. PYLAISIELLA Kindb. Can. Rec. Sci. 1894: 21. 
[Pyzaisia Br. & Sch. Bry. Eur. fasc. 46-47. 1851. Not Desv- 
1814.] 
The generic name Py/aisia was first used by Desvaux in 1814 
to designate a new genus named in honor of De La Pylaie. The 
specimen upon which his genus was founded is stated to be noth- 
ing more than a depauperate form of Hypnum denticulatum L. 
In 1851 Bruch and Schimper took up the name for a new 
genus founded on Hypnum polyanthes Schreb, thus publishing 4 — 
homonym. 
DeNotaris in 1869 extended the genus Pylaisia by including 
Orthothecium of the Bryol. Eur., and in this extended form it was 
degraded by Lindberg in 1879 to a sub-genus of Stercodon of Mit- 
ten. The name Py/aisiclla proposed by ania for two seat
