THE NOMENCLATURE OF THE RECENT CRINOIDS. 
By Austin Hopart Criark, 
Of the United States Bureau of Fisheries. 
In view of the present demand for the strict application of certain 
fixed and definite rules governing all cases in zoological nomenclature, 
it has become necessary to carefully review the literature on the recent 
crinoids in an effort to unravel the somewhat complicated tangle into 
which their nomenclature has been thrown, owing to the unfortunate 
carelessness of a few of the writers on the subject. 
Mr. F. A. Bather has already made a beginning in attempting to 
show where we stand in reference to the genera of Pentacrinitidee 
(not Pentacrinide), and to the fossil genus Hnerinus. Although it 
will be shown that his conclusions are incorrect, except in the case of 
Tsocrinus and Metacrinus (and the first references to both of these are 
omitted), the fact remains that he was the first to realize the necessity 
of a revision of the nomenclature of the recent crinoids, and to act 
upon that realization. 
The present paper is a continuation of the work begun by Mr. 
Bather; anattempt is made to bring together all the generic and speci- 
fic 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. It has not been considered worth 
while in this connection to enter into detail in regard to such genera as 
Astrophyton, Ophiura, and Euryale, belonging to quite a different 
class of animals, as their use can in no way cause any confusion. In 
the numerous cases where a name has subsequently been emended or 
misspelled, each variation is shown, as the changes are often quite 
misleading; while eserichtii, eschrictii, and eschrichti for eschrichtii, 
Actinomedra, Actinometer, and Actrinometra for Actinometra are obvi- 
ous enough, mauonema and mucronata for macronema, variispina for 
varipinna, crassispina for crassipinna, sertosa for sentosa, aster for
