Close relationship of Salpa cylindrica to the other true Salpae seems to be indicated by the close resemblance of their solitary forms and by the 11 • f A resemblance m lorm and © a» musculature between their fig. 89.—Salpa cylindeica, aggregated form, vertical aggregated zooids. The unique character of the eyes of the aggregated zooids is remarkable. They foreshadow, in some regards, the eyes of Thalia, as will be seen 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 United States National Museum; Smithsonian Institution; United States.
