 siecitate spiraliter tortis madore patentibus lineari-lanceolatis apice 

 breviter apiculatis nervo fusco sub apice evanido carinatis integerrimis 

 cellulis basi angustis elongatis superioribus rotundatis diametro cir- 

 citer ^ oVo nnciae metientibus breviter papillosis distinctis, perichsetia-

 trilineari ovali plicata ore intensiore colorato, calyptra nuda. 



Hab. On stones. Cataract Hill, Tasmania, Mr. Archer. 



Leaves longer and narrower than those of M. microstomum, with cells 



far larger than those of the last-named species, having a diameter of 



sifo^^ of an inch. 



M. LiGULARE [Mitten). Dioicum? M. erosulo simile, foliis siecitate 

 tortis subcirrhatis linearibus ligulatis obtusis vel nervo excurrente 

 brevissime apiculatis carinatisque cellulis inferne pro spatio brevi 

 ovoideis cito in rotundatas approximatas papillosas obscuriusculas 

 transeuntibus margine erosulo, perichsetialibus brevioribus ovatis 

 acutis, theca in pedunculo trilineari ovali circa os intensius colorata 

 et plicata, operculo conico acuminato, calyptra nuda, peristomio sim- 

 plici dentibus brevibus. 



Hah. New Zealand, Kerr ; Waikeki, Dr. Sinclair. 

 Smaller than M. prorepens ; leaves more crisped, with cells at their 



bases of an oblong or ovoid form. 



M. EROSULUM (Mitten). Dioicum? caule repente, ramis brevibus sim- 

 plicibus ramulosisve dense stratosis, foliis siecitate compacte tortis 

 incurvisque madore patentibus e basi subelliptica ligulatis obtusis 

 nervo flavo-fusco excurrente breviter mucronatis carinatisque margine 

 papillis prominentibus eroso, cellulis inferioribus elongatis angustis 

 laevibus superioribus apicem versus obscuriusculis grosse papillosis, 

 perichaetialibus paululo latioribus acutis, theca in pedunculo circiter 

 trilineaii ovali fusca circa os intensius colorata et plicata, operculo 

 subulato subsequilongo, peristomio simplici dentibus brevibus, calyptra 

 ramentis appressis sparsis pilosa. 



Hah. New Zealand, Kerr ; near Wellington, Stephenson ; Middle 

 Island, Bidwill; Waikeki, Milne. 

 In habit, size, and colour similar to M. prorepens, but the bases of its 



leaves narrower, the upper portion longer, more obtuse, the cells larger 



and less obscure. M. prorepens is monoicous. 



M. Archeri (Mitten). M. hemitrichodi simillimum, foliis siecitate 

 tortis subcrispatis madore patentibus inferne ellipticis inde lanceo- 

 latis obtusiusculis nervo excurrente carinatis brevissime apiculatis
