on the Parasites ; and Mr. J. Stanley Gardiner, on the remainder of the 
Madreporaria. 
Papers are also expected from Dr. Hoyle, on the Cephalopoda ; Dr. 
Norris Wolfenden, on the Copepoda ; Mr. Forster-Cooper, on the Ptero- 
poda ; Professor Topsent (of Rennes), on the Sponges, ce. 
It is proposed to summarise the zoological results in respect to the 
distribution of marine animals in a Supplementary Part, to be issued in 
1906, when the accounts of certain other groups will have been published. 
This will be sent gratis to subscribers. The seven parts of the Fauna 
and Geography already published form a sufficient guarantee that the 
work will be properly completed, and the Committee consider that they 
may now be dissolved, 
Madreporaria of the Bermuda Islands.—Report of the Committee, 
consisting of Professor S. J. Hickson (Chairman), Dr. W. E. 
Hoye (Secretary), Dr. F. F. Buackman, Mr. J. S. Garprvner, 
Professor W. A. HerpMan, Mr. A. C. Sewarp, Professor C. S. 
SHERRINGTON, and Mr. A. G. TAaNSLEY, appointed to conduct an 
investigation into the Madreporaria of the Bermuda Islands. 
Tue Committee report that they have been in communication with the 
authorities of the Bermuda Biological Station for Research, and have 
been in readiness to co-operate should an opportunity have arisen. They 
regret, however, that such has not been the case, as no naturalist from 
this country has applied for facilities to work in the Bermudas. 
Dr. J. E. Duerden, who hoped to have been able to undertake this 
work, found himself unable to do so. The Committee suggest that they 
should be reappointed, but do not ask for a grant. 
Colour-phystology of the Higher Crustacea.—First Report of the 
Committee, consisting of Professor 8. J. Hickson (Chairman), Dr. 
F. W. Gamsie (Secretary), Dr. W. E. Hoyie, and Mr. F. W. 
KEEBLE, appointed to enable Dr. F. W. Gamble and Mr. Keeble 
to conduct Researches in the Colour-physiology of the Higher 
Crustacea. 
Durine the present summer Messrs. Gamble and Keeble have completed 
a further spell of work on the colour-physiology of the higher crustacea. 
By the aid of the grant allotted to this research, apparatus has been 
bought for the experimental investigation of the chromatophores and their 
contained pigments and fats in Hippolyte varians ; but as the most suit- 
able apparatus has only lately been found after a series of trials, the 
present Report is of an interim and not of a final nature. 
But although the work is still proceeding, Dr. Gamble reports as 
follows on the results obtained up to the present time. The apparatus has 
been set up in Mr. Keeble’s laboratory at Trégastel, Cétes-du-Nord, France, 
with a view of determining (i) the influence of light and darkness on the 
development of the pigments of Hippolyte ; (ii) the comparative suscep- 
tibility of Hippolyte at different periods of life ; (iii) the origin and
