NO. I MEXICAN MOSSES THERIOT 21 



Neither can our species be C. Licbmanni Schimp., for in describing 

 the latter the author does not speak of a border ; besides, he compares 

 it with C. albicans, attributing to it more long-cuspidate and more 

 strongly dentate leaves.

I see in this moss a species entirely independent from F. Havinervis 

 C. M. It is easy to recognize by the smaller and more abruptly nar- 

 rowed leaves, with almost entire margins, a slender costa scarcely 

 reaching the middle, and shorter and wider cells. 



I imagine the author was alluding to the perichaetial leaves when 

 he named this species " dcntata," but it will be agreed that for a moss 

 whose stem and branch leaves are entire the name is rather badly 

 chosen.

Valle de Mexico: Contadero, upon the earth {Bro. Amahlc 1301,

An exact match for the European moss. Cardot described (Rev. 

 Bryol. 37: 50. 1910) a variety amcricana of this species, but the type 

 had not, till now, been indicated in Mexico. It is worth remarking 

 that the moss from Contadero grows upon the ground, a rather rare 

 station for species of the genus Fabronia; yet the classical habitat of 

 F. octoblcpharis in Europe is precisely " earth upon walls."

DitTers from both the type and var. auicricana Card, by its squatty 

 habit, its shorter, numerous, more densely leafed branches ; by its 

 oval and more abruptly acuminate leaves ; by the oval, shortly apicu-
