Abstract
In the course of this work over 3000 specimens were examined and recorded. These came from the two largest collections in New Zealand, NIWA (incorporating the New Zealand Oceanographic Institute) and the Museum of New Zealand. Collections at the Auckland Museum were also reviewed. The order Paxillosida is represented by four families -Luidiidae (1 genus, 5 species), Astropectinidae (8 genera, 24 species), Radiasteridae (1 genus, 2 species), and Porcellanasteridae (5 genera, 7 species). There are eight new species. The order Notomyotida is represented by one family-Benthopectinidae (3 genera, 12 species, none new). Specimens were collected from very shallow tidal areas to nearly 5000 m. A typical specimen is described in detail for each species, and geographic distribution and variations in depth are also discussed. Photographs and drawings of relevant parts are included. In three very common species with many individuals (Astromesites primigenius, Astropecten polyacanthus, and Psilaster acuminatus), a number of specimens were dissected and stomach contents listed. No parasites were observed. Dissected specimens appeared to be in good condition with generally well-developed gonads. Notes on internal anatomy and other features of interest are included where applicable (auths)
