Extract

While collecting in the Shetland Islands during August 1923, I made examinations of many marine animals in the search for protozoan parasites. Among the species examined was Echinus esculentus, and I was interested to note the presence of a large number of ciliates in the intestine of three specimens. I can find no description of this ciliate, and am obliged to believe that it has never been recorded before. This is somewhat surprising, since many of these sea-urchins must be examined every year in zoological laboratories; it is difficult to understand how such conspicuous parasites have escaped observation for so long.
