Although much resembling O. polycaypus, the present species may be 

 distinguished by its shorter leaves, shorter smooth capsule, and especially by 

 its ill-developed peristome. 



0. schisti (Wahlenb.) may possibly be found here, as it occurs in Sweden 

 and Norway ; it is still smaller and denser than O. Bnmioni, with rather obtuse 

 nearly entire leaves, and a striated capsule with lanceolate undivided teeth. 



Sect. 4. RHABDOWEISSIA (Br. Sch.) Lindb. Plants short, densely 

 tufted, leaves narrow, curled, finely papillose in upper part. Caps, sym- 

 metric, not strumose, wide mouthed, 8-striate, when dry 8-sulcate, teeth 

 subulate. 



7. ONCOPHOEUS CRISP ATUS {Dioks.) Lindb. 



Autoicous; leaves flexuose, curled, linear-lanceolate, coarsely 

 toothed at the rather obtuse point. Caps, ovato-globose with a distinct 

 neck, teeth lanceolate, persistent. (T. XXVI, B.)
