Material Examined

The holothurians forming the basis of this account were taken from Cook Strait and Wellington Harbour. The depths worked ranged between 5–10 fathoms and approximately 1300 fathoms. Benthic collections were made with dredge, otter trawl, beam trawl, Petersen grab, or a cone net fished on the bottom. Specimens of two species were kindly loaned to me by the New Zealand Oceano-graphic Institute, and supplementary intertidal species were collected by my colleagues and myself.
