P. arborescetts, Diagnosis. Axinellidae with main skeleton a confused or regular reticulation of styli or tylostyli from which ascending fibres pass outwards to dermis; dermal skeleton in form of bundles of small styli or tylostyli; interstitial spicules, when present, long slender tylostyli. Remarks. The genus includes, in addition to the genotype, P. flabellata, and PlicateUa expama, Thiele. The use of Schmidt's genus Plicatella (1870, p. 45: genotype, Reniera labyriiithka, Schmidt, 1864, p. 39, pi. iv, fig. 9) by Thiele is unjustified, since the only information we have is that the skeleton contains styli only. We know nothing of the arrangement of these styli, and it is probable that Plicatella is more closely related to Stylohalina than to any other genus. At the same time, there is a close relation between Plicatella and Plicatellopsis; but until the type of the former is redescribed it will be impossible to define 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 Institute of Oceanographic Sciences (Great Britain); National Institute of Oceanography of Great Britain; Great Britain.
