Fig. 45.—Trichometra ohscura. Lateral view o f the type. ' Cirri lacking. Radials even with the edge of the centrodorsal; IBr^ very short and band- like, not quite in contact basally, the lateral edges diverging at a rather broad angle ; IBr^ almost triangular, slightly broader than long, the anterior and lateral angles rather strongly produced, with a rounded posterior process incising the IBr,. The ten arms resemble those of the other species of the genus, so far as may be judged from the single mutilated specimen. The longest stump measures 9 mm. to the tenth brachial.
