Clausophyes ovata (Keferstein & Ehlers), 1861. (Text-fig. 67.) Eudoxid. 'Discovery II' (Station 1567) took two anterior and one posterior nectophore, all in very poor condition, in a haul from 1350 m. to the surface, together with an interesting though poorly preserved bract of an eudoxid. This eudoxid bract has a rounded apex, and from the phyllocyst arise a pair of bracteal canals. A free eudoxid of Clausophyes has never been described, and the stem groups have been figured only by Keferstein & Ehlers (1861), when they first described the polygastric stage. The presence of the pair of bracteal canals would seem to link this bract of a free eudoxid with those of Keferstein & Ehlers's attached stem-groups of C. ovata. Chi. 2. mm 1 Text-fig. 67. Clausophyes ovata. Bract of eudoxid. 'Discovery II' St. 1567, 1350-0 m., x 25. Material. 'Discovery II' has taken this species in twenty-three closing-nets so far examined, at depths ranging from 3000-2000 to 310-260 m. It seems to be characteristic of the deeper water. My identification of ovata is based on the posterior nectophore which has a straight, not emarginate basal edge to the mouth-plate. The left hydroecial fold fits into a notch at the basal end of the right- hand fold. The notch is bounded on the inner side by a prominence which forms a good recognition mark. In a new species from 'Discovery II' Station 2084, whose description I am unable to complete at the moment, the posterior nectophore is intermediate
