. Annotationes zoologicae japonenses / Nihon do?butsugaku iho?. 592 MEGUMI YERI AND TOKIO KABURAKI : Fig. 1. Fig. I. Neostylochtis fulvopunctatus, n. gen., n. sp. Drawn from the living specimen. head margin. The middle parts of that tract join posteriorly the area of cerebral eye-spots ; in the lateral parts there exist only one or two eye-spots in its width. The ends of the tract reach posteriorly to about the level of tentacular eye-spots. The brain occupies a position about one- fourth the length of body from the anterior end. Body-wall.—The epidermis consists as usual of a layer of columnar ciliated cells, which contain some minute rhabdites and are of a greater height on the dorsal than on the ventral side. The cilia are much more strongly developed on the dorsal side than on the ventral surface. Numerous glands, deeply situated in the body on each side, open to the exterior in a narrow zone of the ventral surface along and just within the body-margin. The 111 same. J * ° basement membrane is fairly well developed. The dermal musculature, situated immediately below it. consists of the externalmost longitudinal, the middle diagonal and the innermost circular layers. Digestive System.—The mouth is situated slightly in front of the middle of body and at nearly the centre of the pharyngeal pocket which is of a length somewhat less than one-half that of the body and is provided with at least 12 diverticula corresponding in a general way to the folds of pharynx. The rather narrow main gut, longer than the pharyngeal pocket, gives rise to numerous pairs of lateral branches with occasional, alternately standing outbulgings, which do not undergo anastomosis. The gut-epithelium presents no noteworthy. Fig. 2. Fig. 2. Distribution of eye-spots.
