This paper tries to unravel the somewhat complicated tangle of nomenclature to where the crinoids find themselves. This work is assumed to be a continuation of the work begun by Mr. Bather; an attempt is made to bring together all the generic and specific names which have ever been applied to recent crinoids (and names of genera which have been used for recent species), giving the correct first reference, the types of genera and the type-localities of species, the derivation of the names, and the present locality of the type specimen of each species, so far as known. The revised international code has been followed strictly.
