Dr. Vasey’s various publications have determined the arrange- 
ment, &e., of Graminee ;1 Lesquereux’ and James’ that of the 
Musci;? the late Prof. Tuckerman the Lichenes;* Mr. M. C. 
Cooke’s arrangement of the Fungi* has been followed, with revis- 
ions by Mr. Peck and Mr. Ellis; Dr. Farlow has been the guide for 
the Marine Alge,®’ and Rev. Mr. Wolle for the Fresh Water Alge.® 
It should be noted that for convenience’ sake the Marine and 
Fresh Water Alge are separated, and in the one is followed Dr. 
Farlow’s ascending, and in the other Mr. Wolle’s descending 
series. Although unscientific, it was believed that there were suf- 
ficient advantages in not merging all the Alg@ under one syste- 
matic arrangement. The arrangement of the Diatomacee’ is that 
in Pritchard. We follow Prof. Underwood’s arrangement of 
Hepatice.*® 
The Musci were determined or previous determinations verified 
by Mr. Lesquereux. Some of them, however, and all the Hepa- 
tice, passed through the hands of the late Mr. Coe F. Austin. 
The late Prof. Tuckerman very kindly determined, or verified, 
the Lichenes, and all herein named passed under his examination. 
The Fungi were all named by the late Rev. Dr. M. A. Curtis, or by 
him in connection with Dr. Berkely; the revision of the same by
