This specimen was observed early in this work (in 1928) and unfortunately it was neither carefully drawn nor preserved for further study. This bud was probably of the type which has appeared on regenerates at the eighth segment and somewhat more posterior levels. All other pieces at this level which survived for 15 days had produced complete new buds by that 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 Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
