Abstract

Outlines are given of the body form in the extant families of the stalked crinoid orders Millericrinida and Bourgueticrinida with particular notes on the few taxa exhibiting secondary arm branching.

The recent nominal species of the Bourgueticrinida are listed in a table, together with their distributions and an indication of the size range of the often limited known material. The wisdom of division of these taxa into more than the one family Bathycrinidae is questioned, in view of recent observations on ontogeny and variation, particularly with regard to the stalk attachment.

A new record of a particularly relevant species, Porphyrocrinus thalassae Roux, is included, with a photograph showing the secondary arm branching.
