a bright green colour, due to the presence of a dense stratum of 
somewhat large Chlorophyll granules; the pseudopodia not .nume- 
rous, but very long and comparatively stout. This could hardly be 
Actinophrys viridis (Ehr.), which is described and figured as minute, 
and possessing a dense fringe of very fine and slender and short 
pseudopodia. As regards the present form, however, Mr. Archer 
■would prefer to postpone any further remarks upon it until he had 
an opportunity again to examine examples of it, suspecting it to 
present a certain speciality which would deserve a much closer 
investigation. 
Dr. E. Perceval Wright exhibited spicules of a minute sponge, 
brought up from a depth of 1913 fathoms in lat. 58° 23" N., 
long. 48° 50", by Dr. Wallich. This sponge evidently belonged to 
the order Yitrea. It was attached by a stalk to a small piece of 
rock, and the upper or body-portion was about the size of a small 
pea. A beautiful network of spicules surrounded the whole mass, 
and underneath this there was a series of the spicules called dicho- 
tomo-patento-ternate by Bowerbank, as met with by him in Dacty- 
localyx BowerbanJcii. Beyond the record of its occurrence, for 
which he was indebted to his friend Dr. Wallich, he would not 
further for the present allude to it. 
Mr. Woodworth exhibited various photographs of his own pro- 
duction of microscopic objects, including crystals, which were 
exceedingly sharp and accurate. 
Resolved — That this Club desires to place on record the deep loss 
which they have sustained by the death of Dr. Maurice H. Collis. 
Dr. Collis was elected as an ordinary member of our Club some years 
ago, and his place now vacant will not be easily filled. Devoting 
himself chiefly to the use of the microscope in connection with the 
active exercise of his profession, he laboured in this department of 
research with very considerable success ; while his pleasant social 
qualities and extreme good nature endeared him to the members of 
our little circle. In placing this record on the minutes, it will not 
be forgotten that this is the first loss by death of an ordinary 
member that this Club has experienced since its formation.

Mr. Archer brought forward a number of Desmidiese, taken at 
Glengariff on the occasion of a recent excursion thither with Dr. 
Barker and Professor E. P. Wright, some of which deserved a closer 
examination, and to a few of which he hoped again to revert. 
Amongst those now shown was a large Staurastrum, which he had 
very sparingly taken last year in Connemara, but of which he had 
then tried to find specimens for exhibition at a meeting of the Club, 
but without success upon that occasion. This was a large tri- 
radiate form, in some measure resembling Staurastrum spinulosum 
and St. vestitum, but much larger and stouter than either. A 
special description he would defer. There was also a Cosmarium,
