Recent collections of crinoids from the intertidal zone to 1,650 m in the tropical western Atlantic have provided significant range extensions for more than half of the 44 comatulid and stalked species known from the region. Of the 34 comatulid species, over 60% are endemic to the region; of the 10 stalked species, 90% are endemic. At the familial level, this fauna has its strongest affinities with the tropical Indo-Pacific region. Comatulids are most abundant above 300 m, while stalked species occur primarily between 100 and 700 m. Species that occur primarily above 600 m (the deepest penetration of the …

The formerly monotypic genus Comactinia is found to comprise two valid species. One of these is further divided into two subspecies. The variability of the genus is examined and illustrated. A discussion of ecology, affinities, and zoogeography is included.
