Sea-Stars (Echinodermata: Asteroidea) from "Eltanin" Cruise 26, with a Review of the New Zealand Asteroid Fauna

Introduction

Introduction

In late November and December 1966, the USNS Research Vessel "Eltanin" occupied 36 stations, (both biological and hydrographical) in New Zealand waters between 38° and 47° S., and 160° and 175° E., in depths ranging from 25–4,956 m. Starfish (Asteroidea) were taken from only 8 stations and these are described here. Classification used in this paper follows that set out in the Treatise on Invertebrate Palaeontology (1966).

In general a 5′ Blake trawl was used for dredging; a larger 10′ Blake proved unsatisfactory. Colour notes in the text are of freshly caught specimens. The present addition to the New Zealand fauna of 6 genera of starfish which are new records for New Zealand and of 2 new species, together with recent records of McKnight (1967, 1968), has prompted the following review of the literature and the check lists.
