As the Collection is liable to continual change, — from the 
transfer of specimens to more convenient quarters ; from ca- 
sualties, or other causes of removal from the gardens ; and 
from accessions ; — some irregularities may be observed in this 
List, notwithstanding the accuracy of the account at the time of 
its going to the press. These will be corrected in the succeeding 
Editions, and new ones will be put forth so frequently as to ob- 
viate as far as possible the inconvenience alluded to. 
N.B. It is to be observed, that the Council of the Society 
do not hold themselves responsible for the Nomenclature used, 
nor for any Opinions expressed, or Statements made, in this 
Publication.
