Cucumaria paraglacialis, deposits of the body wall. Genus Abyssocucumis n. g. Staurocucumis partim. Ekman 1927: Holothurien, Deutsche Siid- polar-Expedition, p. 374. Diagnosis: Fairly small fusiform eucumarids with no distinct difference between bivium and trivium. With ten equal tentacles and with the water-vascular appendages in two alternating rows along the ambulacra, and totally lacking in the interambulacra. Calcareous ring well developed and simple, without any posterior prolongations. Intestine with muscular stomach, pohan vesicle and stonecanal single, and respiratory trees more or less reduced. Retractor muscles for the larger part free, only united by the longitudinal muscles by a web close to their base. Calcareous deposits of the body wall proper exclusively four- armed crosses with perforated ends and an excentrically placed spire or with no spire, and then with the one arm spinous, resem- bling a spire. This latter case the more common in large specimens. Genotype: Cucumaria abyssorum Theel. Remarks: The species Cucumaria abyssorum Theel was referred by Ekman in 1927 to his new genus Staurocucumis in which he was later followed by Clark and Deichmann in then paper: 'n Psolicucumis Heding and its Allies.' A closer study of the literature and'of a fair number of specimens, both of Ikiii- villei Vaney and turqueti Vaney collected by the 'Terra Nova' Expedition (the report of the Holothurians of the 'Terra Nova' Expedition will appear later in connection with that of the •' Expedition1) definitely shows that the genus Staurocucumis, as established by Ekman, cannot hold good, and I it must be divided into a number of quite different genera. This will not cause surprise, as Ekman himself, in discussing the genus more carefully, shows how clearly liouvillei differs from the other
