M'Ardle — On the Musci and Hepaticce of the Co. Cavan. 615 



Bor have I seen Irish specimens of it " (Proc. K.I.A., 2nd Ser., 

 vol. ii., Science, p, 652). The ventricose group of Jungermania are 

 difficult to identify without a series of specimens in good condition. 

 The descriptions given in synopsis by authors are often too brief, and 

 suggest slight differences when the plants are distinct enough.
