liography of fifty-one titles follows. The plates illustrate various details of 
Dicranella sguarrosa, Bryohrittonia pelliicida, and Trachycystis flagellaris. Each 
species has detailed citation of the collections there referred, and a general 
outline of the Alaskan distributions. More extended notes on various topics 
are given for many species; especially Geehehia gigantea (Funk) Boul., Zygodon 
Reinwardtii (Hsch.) A. Br. (both new to America), Trachycystis flagellaris [S. 
& L.) Lindb., Bartramia hreviseta Lindb., Philonotis Arnelli Husn., and Brachy- 
thecium pacificum (R. & C.) Grout.

J. Am ANN. — L'indice cellulaire chez les Muscinees. (Revue bryologique 
48: 33-38. 192 1.) — The dimensions of the foliar cells in mosses frequently 
enable one to distinguish closely related species, even though the foliar cells 
vary considerably on different specimens. The author proposes to supplement 
the present method of stating length and width of cells by an Index cellulaire " 
based upon the average of measurements of the number of cells per square mill- 
imeter in the median leaf surface. These measuremants also produce more 
exact values for the length and width measurements. The author gives careful 
directions as to methods, errors to be avoided, and cites a large number of ex- 
amples illustrative of the method and its utility.

gives notes upon a number of other species new to the New Caledonian flora, 
and corrects certain errors in previous determinations. The new genus Bryo- 
broihera is proposed for the species known as Mesochaete c^enulata Broth. & Par.
