Grimmia torquata, Hornsch. Since the description of the fruit 
was published, (BULLETIN, xvi. 107), Mr. Leiberg has col- 
lected much finer specimens showing the fugacious peristome, 
and annulus. The teeth are short and broken, with a median 
line; the annulus is composed of many rows of cells, falling 
in fragments with the lid. (See Rev. Bryol. xvi. 64).

above rounded, hexagonal, nearly 1 in diameter, faintly sinuous 
and oblong at base, discolored, with slight enlargement at the
