K PROCEEDINGS LIVERPOOL BIOLOGICAL SOCIETY. 
A vote of thanks to the President was proposed 
by Mr. Leicester, and seconded by Mr. Morton, 
and carried unanimously. 
6. Prof. Herdman read a communication on ‘‘ Ostrich 
Breeding”’ by Mr. Thomas Tillrook. 
7. Prof. Herdman exhibited a pink marine micro-organism, 
with the following remarks:—While dredging 
lately in Loch Fyne I noticed through the water 
in a little shallow bay on the north side of the 
entrance to East Loch Tarbert, a number of pink 
patches on the sand. These could just be reached 
by wading from a boat at the lowest tides, and 
were then found to be roughly circular spots about 
a foot in diameter where the clean white sand was 
discoloured, most of the surface grains being almost 
exactly the tint of ordinary pink blotting paper. 
Under a low power of the microscope it is seen 
that the pink particles are ordinary clear quartz 
sand grains encrusted with little bright pink jelly 
masses generally of elongated or sausage-like forms 
and averaging O'l mm in length. Further mag- 
nification shows that each jelly mass is crowded 
with minute very short rods, or ellipsoids, of about 
00015 mm in length and about half as much in 
breadth. This appears to be a micro-organism in 
the zooglcea condition, and I do not know that any 
such pink marine form living on clean sand in 
pure sea-water has been noticed. It may possibly 
be one of the forms of Beggiatoa rosea-persicina, 
but it does not agree satisfactorily with any of the 
descriptions I have seen. 
*. R. J. Harvey Gibson, M.A., F.L.S., exhibited and 
made a few remarks upon some Fresh-water Algze 
from Lismore Lochs.
