Mistaken for G. Hartmanni, Schimp. (BULLETIN, xvi, 340, 

 and Rev. Bryol. xvii, 16) which it so closely resembles that the 

 figures given by Husnot (Muse. Gall. t. xxxix) and Braithw. 

 (Brit. Mosses, t. xlviii.) would do for either. Specimens were 

 sent to M. Philibert, whose excellent description in the Revue Bry- 

 ologique xiv. p. 50, seemed to me to answer perfectly to my 

 specimens. He kindly sent me fruiting specimens from Corsica, 

 which differ in the plants being much larger, with stems 6-^ cm. 

 long, leaves much twisted and secund, narrower and longer, much 

 less deformed by propagula; with cells much more sinuous and 

 the teeth of the peristone less papillose and bifid? so drawn by 

 Mr. Anderson to whom I sent the only perfect peristome of G. 

 Hartmanni. But it is evident that this is not always true, for 

 Philibert says of these same Corsican specimens " Dents lanceo- 

 lees-lineares, obtuses, entieres, d'un rouge orange assez pale; 

 tres-lisses dans les deux tiers inferieurs ; le tiers superieur, lei^^ere- 

 ment papilleux." Ours are not obtuse, bright red not orange- 

 colored, and conspicuously papillose. The difference between 

 figs. 28 and 35 is also not so great in all specimens, these being 

 extremes. 



Dedicated to M. H. Philibert, Prof honoraire de la Faculte 

 de§ lettres, Aix, Bouches-du- Rhone, France, who has kindly 

 furnished me with fruiting specimens, and who says: " Je croix 

 que cette forme dois constituer une espece nouvelle."
