2 MARINE BIOLOGY OF THE SUDANESE RED SHEA. 
shown himself to be a keen and indefatigable collector and an accomplished 
Zoologist will be abundantly evident from the pages that follow in this Report ; 
but I am glad to have this opportunity of stating also how agreeable and 
helpful he has been throughout our intercourse, and how much pleasure it has 
given me to be associated with him in this Joint enterprise. 
Mr. Crossland left England in October 1904, and, after some necessary 
and not unprofitable delays in Hgypt, reached the Red Sea and eventually 
Suakim early in 1905. He remained in that neighbourhood cruising both to 
the north and south, exploring the reefs and lagoons and investigating the 
marine fauna and flora in every possible way until May, and then returned 
home, bringing considerable collections which were partly sorted out and 
distributed to specialists during the ensuing summer and autumn. 
These are the groups that will be reported on first in the sections that follow 
in the present volume. The rest of the collections are now being arranged 
in Liverpool under my supervision. There is a considerable amount of work 
to be done on such groups as the Crustacea, for example, in sorting out the 
material for the specialists ; but I hope soon to have them all in the hands of 
those authorities who have kindly undertaken to examine and report. 
In the winter of 1905 Mr. Crossland returned to the Sudan to an inde- 
pendent post, no longer under my direction. Asa result of the conditions of 
his new appointment our original plan of work has required to be modified, 
and a comprehensive joint report such as we at first contemplated is no longer 
possible. With regret I have had to cancel, or at least indefinitely postpone, a 
title-page, which with other MSS. Mr. Crossland left in my hands, referring 
to such a general report under our joint authorship. It is just possible that 
if conditions are favourable we may be able to produce such a work at the 
conclusion of, or as an appendix to, the present series of reports. In the mean- 
and he is much further, in time, from 
time, in my fellow-worker’s absence 
Suez than we are—I have had to do what seems best with the MSS. and the 
collections left in my care ; and, with the kind advice of my colleagues at the 
Linnean Society, I have considered that to publish the following series as 
reports upon Mr. Crossland’s collections, under my editorship, will best meet 
the views of all concerned and the interests of science.
