The material forming the basis of this report has been collected by various institutions, as follows:

Department of Zoology, Victoria University of Wellington Deep water investigations in Cook Strait have revealed four bathyal species of holothurians, namely Paracaudina chilensis (Müller), Molpadia violacea (Studer), Heteromolpadia marenzelleri (Theel), and Benthodytes hystrix Sluiter. The first three of these species are considered in detail elsewhere (Pawson, 1963). Stn. VUZ 109 off Palliser Bay, 41° 50′ S., 175° 5′ E., 29/12/57, ca. 600 fathoms. (1,080 metres), mud, 4 metre cone net fished on bottom.
