exhibitions on five occasions. Five communications also 
appear under the authorship of Commander J. J. Walker. 
A specially interesting feature in the long list printed 
in the Contents is the constant recurrence of the names 
of naturalists in other lands as the authors of commu- 
nications. Thus the observations of Mr. S. A. Neave 
were made in North-Eastern Rhodesia, Mr. C. N. Barker 
and Mr. G. F. Leigh in Natal, Dr. S. Schonland in British 
Bechuanaland, Mr. C. A. Wiggins in British East Africa 
and Uganda, while Mr. H. A. Byatt dealt with material 
from the sources of the Congo. It is also a great pleasure

Vernon L. Kellog of California, and Mr. Abbott H. Thayer 
of New Hampshire. Mr. J. C. Kershaw’s observations 
were made in the neighbourhood of Macao and Hong 
Kong, Mr. F. P. Dodd’s in North Queensland, Major 
Neville Manders’ in Ceylon, Mr. L. Andrewes’ in Southern 
India.

Department during the years 1903, 1904, and 1905 will 
be found in the Reports of the Professor (22-24). 
Nearly three years have elapsed since the appearance

volumes. These larger papers are gradually accumulating 
until their numbers will admit of a special issue. Several 
memoirs now going through the press were written within 
the period covered by volume V. The manuscript for 
a complete volume on the W. J. Burchell Collections was
