 was published, (BULLETIN, xvi. 107), Mr. Leiberg has col-

 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).

 ing above ; leaves erect-incumbent when dry, not secund, spread- 

 ing when moist, 1^-2 mm. long; lanceolate, carinate, with re- 

 curved margins, and toothed hair-points 15 mm. long, but

 the tips of the leaves or retire and bifid along the midvein ; cells 

 above rounded, hexagonal, nearly i/< in diameter, faintly sinuous 

 and oblong at base, discolored, with slight enlargement at the 

 basal angles; vein heavy i^ fx wide at base, rounded at back, 

 sulcate above. Perichsetium also deformed, leaves broader, inner 

 short, triangular and hyaline at base. Pedicels one or two from 

 the same perichaetium ; seta twisted, variously bent, 3-5 mm. 

 long; capsule i mm. long, broadest at the mouth, smooth when 

 dry, pale with a red rim ; columella long, slender, excurrent; 

 teeth recurved, red, undivided, with five or six short, broad seg-
