double perfect, teeth brown, inner membrane deep, carinate seg- 

 ments open along the keel with 3-4 slender, papillose, appendicu- 

 late cilia; spores brown .013-.016 mm. 



Resembling B. ccniiiiiui Hedvv. in the bright yellow color of its 

 capsules, but a larger and coarser plant, seemingly one of the 

 smaller Rhodohryums, with the leaves twisted when dry, allied to 

 B. andicola.

These specimens were compared at Kew with all the species 

 described by Mitten (Jour. Linn. Soc. 12, 320) having leaves at 

 all similar and found to be most nearly related to M. diplodontay 

 but as the fruit is too immature to determine any peristome char- 

 acters, it cannot be safely referred to any of them. A portion 

 sent to C. Mijller was named by him MielicJilioferia modesta n. sp.

Plants dark red, glossy; stems erect, unbranched 5-6 cm. high, 

 leaves erect, 5 mm. long, closely imbricate with a brown clasping

 apex. Pedicels stout, erect, 2-3 cm. long, bright fulvous, capsules 

 horizontal 4-5 mm. long; lid conic, beak hooked, 2 mm. long. 



Compared with P. nibiginosiis Mitt, no, 21 1, J. Weir, Andes

 aristatiis Hpe., no. 2002, Lindig, New Granada, Bogota (1859), 

 and another not numbered, collected in 1863, in the fewer but 

 larger multicellular teeth and short cuspidate apex as well as in 

 the longer pedicels and larger capsules of Dr. Rusby's plants.
