[ August, 



name? Shall it displace Scapania or Plagiochila? Or in a 

 case which involves so much difficulty and can certainly dis- 

 turb nothing outside of the three genera in question, is it not 

 the part of wisdom to reject Gray's name and leave the three 

 names so long established intact, as has been done by Spruce, 

 Carrington, and most of the English school. In any case the 

 adoption of Martinellia for Scapania, as done by Dr. Lind- 

 berg, is unwarranted. 



The relations of these early established genera may be 

 made more clear by the following table :

Since the publication of the Descriptive Catalogue 1 ', 

 many changes have become necessary, some of which had 

 escaped notice at the time of publishing that paper because 

 of the absence of much of the scattering hepatic literature, 

 and many more from the investigations made since its publi- 

 cation In the review of the species of the "manual region" 

 the following changes become necessary, and since necessa- 

 ry 1 he sooner we become familiar with them the better: 



frullania Grayana (p. 66) becomes F. Asagrayana, the 

 original form of the name, which has been misquoted by Am- 

 ericans in its shortened form, beginning with Sullivant.
