): The choanosomal skeleton is composed of diactins 700–3800 µm in length and 4–15 µm in diameter; they have rounded, rough outer ends and stout, smooth shafts. Hypodermal pentactins have orthotropal tangential rays about 800–1700 µm in length and 8–24 µm in diameter, the proximal ray is more than 1400 µm in length. Some of the tangential rays are smooth, the others have rough surface; the outer ends are conically pointed. Dermalia are stauractins, rarely tauactins and pentactins, sometimes they have 1–2 rudimental tubercles instead of the reduced rays. The rays of dermal stauractins are rough with rounded or conically pointed outer ends, have 59–111 µm in length (n=25, avg=93, std=12) with a diameter of about 5 µm. Atrialia are hexactins, their rays directed inside the atrial cavity are 67–215 µm in length (n=23, avg=161, std=36), tangential rays are 74–200 µm in length (n=24, avg=146, std=30), ray directed inside the body is 41– 207 µm in length (n=22, avg=138, std=36). The rays are 5–7 µm in diameter, their surface is rough and outer ends are rounded or conically pointed.
