However, there is some inconsistency in terminology since he explicitly refers to the 'much reduced ventral most one pair of branchiae', and branchiae are also referred to as 'filaments' (= radioles). There is, therefore, room for doubt, and one might infer that his 'palpi' are located on the dorsal side, and may actually be elongated rudimentary opercula. The condition of the thoracic membranes in P. pacifica is not clear from the description. They sharply decrease in width posteriorly from the 5th chaetiger onwards and are insignificant or lacking as they approach the end of the 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 Natural History Museum (London).
