Hab. Tasmauia, Cheshunt, Mr. Archer. 
Half an inch high. Seta scarcely two lines long. Iu general appear- 
ance nearly allied to F. pallidus, but its leaves are entire, the cells 
smaller with thicker walls, male flowers absent. In the few specimens 
yet seen, the plants are, above brownish yellow, below black.

Acrocarpica. -Folia cellulis hexagonis areolata. Peristomium externum

Calyptra mitriformis parva.

Hab. Tasmania, below the quarry, Ovens Creek. 
Stems from one-fourth to half an inch high, dull green, considerably 
resembling some small species of Fissidens; its affinity is, however, to 
Schistostega, with which it agrees in the vertical insertion of the leaves 
of its barren stems, but recedes in the presence of a rather stout nerve 
and the regular hexagonal cells. In the structure of its peristome it 
approaches to Aulacomnion. The calyptra is smaller in proportion than 
that of Tetraphis or Tetrodontium.
