Living specimens on pinnules of prostomial cirri of 5\ insignis. FIGURES 2, 3. Transverse sections of specimens attached to pinnules. Buffered osmium tetroxide; Epon sections, /u; methylene blue-azure II. ciliate unless I examined every one of the hundreds of pinnules of the prostomial cirri. All worms from both of the localities were parasitized by Ignotocoma sabellarum. When cirri of a host sabellid are examined under lower magnifications, the ciliates appear as rather clear, wart-like protuberances (Figs. 1, 4). They are restricted to the frontal surfaces of the pinnules. Ignotocoma sabellarum, on the other hand, lives attached to the main stems of the cirri and their branches as well as to the pinnules, but it is not common on the frontal surfaces. In most individuals of S. insignis observed to be parasitized by P. verrucijormis, relatively few ciliates were present. Sometimes I noted only one or two specimens on widely scattered pinnules. In other instances, a number of specimens were found on several adjacent pinnules of certain cirri. When heavy and more or less general infestations were observed, perhaps half of the many pinnules on each cirrus had at least one or two parasites, and up to 12 specimens were observed on some pinnules. As a rule, the ciliates were more abundant on the pinnules arising.
