Diagnoses in taxonomic order
Diagnoses in alphabetical order
Diagnoses of supraspecific taxa
This list is derived from the famous "Smiley-Pawson List," an unpublished, annotated catalogue that circulates amongst holothuroid taxonomists. While still in revision, it is nevertheless currently the most authoritative complilation of holothuroid nomina since Herbert Ludwig's (1892-1896) overview. Each link provides the estimated number of subsumed taxa and diagnoses taken from the literature to about 1990. The list below can be viewed in both taxonomic and alphabetical order.
