Boccardia columbiana. anterior end (x70) Figure 2. Boccardia proboscidea. anterior end (x50) diuni is weakly-developed, it has only a few short setae and a small post-setal lobe; its neuropodium is also poorly developed (see Fig. 2). Specimens of both species were taken from piling material at Ca^oi- cos. central California; they measured to mm. long. Boccardia proboscidea was more heavily pigmented in the region of the pros- tomiimi and also on tlie dorsal surface of segments 2 and 3. Boccardia columbiana showed only one of 11 specimens %'\ith a heavily pig- mented prostomium and none had dorsal pigment on segments 2 and 3. Generally, the largest B. proboscidea from the piling material had the greatest amount of pigment; however, specimens ( to mm.) from the back bay marina nmd in Morro Bay showed very little pigmentation even along the prostomium. The forms thus are similar in general pigmentation but the amount and distribution may vary between and within the species according to age. habitat, and possibly method of preservation. It has not been possible to ascertain a definite pattern of pigmentation for all members of either Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Southern California Academy of Sciences.
