Kinestoskias oblongata sp: nov.(text-figs. 1-6) Colony consists of a tubular stalk and a typical palm-like branch whose end is not curved. The branch consists of two rows of alternative zooids. The tubular stalk is 80 mm. long, and is a kenozooid with thin membranous wall, uniformly wide throughout the portion above the proximal end. From the base of the stalk are given off minute rootlets. At the distal end of the stalk, near the primary zooid of the proximal end of the branch, the stalk lumen is expanded into membranous aperture, a portion of the distal end of which is raised toward the frontal surface, on the dorsal surface. The wall of the stalk is arched. It is to this are-like area that a large pyriform structure is attached. The attachment plane of this structure has the same curvature as that of the tubular wall. The structure is broader basally than distally and is connected with the proximal end of the primary alternative zooid of the palm-like branch by a chitinous joint. By another such joint the proximal end of the second alternative zooid in the proximal end of the branch is also connected with a small conical structure attached on the disto-dorsal edge of the above-mentioned arc-like area. The fifth alternatively arranged zooid distal to the stalk takes part in the bifurcation. Zooids are oblong, narrower proximally, their distal end sloping slightly and obliquely toward outer distal corner, usually with or occasionally without a small spine(not jointed at the base),inner distal margin round; their dorsal surface is convex and smooth.The outer proximal side of each polypide has a columella-like process, to which tip are attached the muscles; musele fibres are rather strong, penetrating into the lateral and dorsal wall of the polypide which is large and occupying about the anterior or more than half the length of the zooid. The lophophore is small, tentacles about 24 in number. Avieularia are small, attached to the outer side of the middle of the proximal half in a zooid. They are of the elongated type, their base is narrow, their profile is nearly straight, their rostrum is short and inconspicuously hooked, their mandible is simple and triangular. Usually most of the avicularia extend to the frontal surface of the zooids. Ovicells are broader than long, attached to inner distal corner, obliquely covering the surface of the neighbouring zooids. The eetooecium is separated from the entooecium by a space. The entozooecium is marked by a longitudinal line or slit perpendicular to the ooepore, and by many stripes parallel with the ooepore. This new species bears a resemblance to Kinetoskias elongata Harmer 1926. In the. latter species the zooids are elongated, the avicularia are located cephalad of the midpoint of a zooid, the ovicells are marked only by the radiating lines. In this new species the zooids are oblong, the avicularia are located caudad to the mid-point of a zooid and the ovicells have peculiar stripes.
