A small species measuring about 12 mm. in length for be- tween 50 and 60 chaetigers. In spirit there is no colour. The head (Fig. 21 fl) is broader than long and rounded in front. There are two pairs of eyes. The tentacles, tentacular cirri and the dorsal cirri throughout the body are all very similar in shape and size. They are simple, subulate structures, somewhat thickened basally and tapering to a point, and their size is about equal to half the breadth of the body. The ventral tentacular cirri are a little smaller than the rest. The pharynx extends to about the 4th chaetiger and the proventriculus to the loth. The pharyngeal tooth is anterior and the mouth of the pharynx is smooth and sur- rounded by a circlet of 10 papillae. The feet (Fig. 21 b) are more or less triangular in outline and supported by three acicula. The bristles are all bidentate and the end-pieces have a characteristic aspect, for the denticulations show a great increase in size from above downwards (Fig. 21c). The ventral cirri are small and conical and scarcely reach to the end of the foot. There is a pair of pygidial cirri resembling the normal dorsal 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.
