specimens have the peristome teeth scarcely or not striate 
on the surface, with apex truncate and extending only about 
80 p above the mouth. 
FABRONIA SINGULIDENS C. M. 
Pelichuco, 3300 meters, on rock, May 5, 1902 (2774). By 
the stem-leaves this species is rather related to Andzna, but 
the perichaetial leaves are more or less truncate and irregu- 
larly serrulate above, sometimes with a short abrupt point, 
and the peristome teeth extend about twice as far above the 
mouth of the capsule, with mostly acute, irregularly erose 
apex. The surface of the teeth is striate in various directions.

Helicodontium spicatinervum sp. nov. 
Autoicous: in low, loosely cespitose mats with creeping 
stems and irregular branches about one half cm. long; stem- 
leaves not plicate, scarcely 1 mm. long, erect or somewhat 
spreading when dry, rather widely spreading when moist, 
from a broadly ovate base gradually tapering to a short, very 
acute apex, finely serrulate all round to the reflexed border 
near base, with stout nerve extending about two thirds up and 
ending in short spine on back; leaf-cells narrow and thin- 
walled above, toward the basal angles becoming broader and 
shorter, the median cells up to “Op wide and 4oyz long; 
branch-leaves shorter and broader pointed; perichaetial 
leaves pale, more or less costate below, the inner gradually 
lanceolate pointed, serrulate on margin, up to 1.6 mm. long;
