the latter. The iuner peristome has been figured by Mr. 

 Sowerby as that of a Leskea ; but in all the specimens that we 

 have examined, there may be observed short, filiform pro- 

 cesses between each segment of the inner peristome which 

 constitute it a true Hypnum. 



26. H. nitens ; leaves erecto-patent lanceolate-subulate acuminated 



nearly entire striated the nerve running nearly to the summit, 

 capsule oblongo-ovate curved cernuous, fruitstalks smooth, 

 lid conical. (TAB. XXV.)

Dillenius did not know this fine moss as British. We are 

 indebted for the discovery of it to Mr. Dickson, and to Mr. 

 Dalton for specimens with perfect capsules. It approaches very 

 near to the last mentioned species, but differs by its larger size, 

 more upright and pinnate mode of growth, orange brown 

 colour, shorter lid, and longer capsule. 



27. H. albicans ; leaves erecto-patent ovato-lanceolate acuminated 



striated entire the nerve reaching half way up, capsules ovate 

 cernuous, fruitstalks smooth, lid conical. (TAB. XXV.)
