Obs. — This rare species, discovered on Bow Fell by Mr. George 

 Stabler, is distinguished from an}^ of the Ceslm by the presence of 

 a true perianth, from Marsupella usfidafa {Hilben.) by its closer 

 appressed leaves, which are more oval, with shallower sinus and 

 more obtuse segments. For further interesting notes see Dr. 

 Spruce's excellent paper m Revue Bryologique for 1881.
