OBSERVATIONS ON THE PROTOZOA 
341 
fragments of these zootliecia were found in a small pond, but 
these were sufficient to identify the beautiful flabellate colony 
figured by Kent in his Plate XVI. As the tubules were never 
found growing in more than one layer the species huxleyi was 
ruled oui. Maximum length of fragments found 100 microns. 
Diameter of tubule .8 micron.
