By D. Sharp. 
As the system, used in previous volumes, of arrangement of the titles of 
memoirs has not proved so advantageous in facilitating reference as was 
anticipated, and as it had the disadvantage of compelling search in a 
number of widely-separated pages, it has been decided that a change in 
this respect may be introduced. Accordingly, the titles of memoirs in 
the orders recorded by me are here placed together. This list of titles is, 
however, far from being exhaustive. The titles of small notes are not 
included ; in many cases, when the w'hole contents of a memoir are 
recorded piecemeal in the systematic portion of our Record, the title is 
omitted, and sometimes, when the subject treated is very restricted, the 
title itself is placed in the systematic record. The chief difficulties 
experienced have been in regard to synonymy and to varietal names. 
As to the former, I think it is much to be desired that writers when 
introducing a new synonym should accompany it by some distinctive 
mark, such as “ n. syn.’’ As to varieties, I have included some new 
varietal names, but others are passed over without notice. 
It is with much pleasure that I am able to preface my portion of the 
Record by an expression of thanks to my predecessor, Mr. W. F. Kirby, 
for the kind manner in which he has communicated information about 
several matters to me. D. S.

The more important of these observations are recorded in the syste¬ 
matic part of our Record ; but the memoir contains also numerous minor 
observations of value.
