NO. 1623. NOMENCLATURE OF RECENT CRINOIDS—CLARK. 437 
it has been thought best to here call attention to certain flagrant errors, 
for instance where, as in the case of Antedon capensis, Antedon sclaterc, 
Antedon magnicirra, Antedon scalaris, and Antedon bassett-smithi, 
species have been described in ‘* groups” widely different from those 
in which they belong. These cases, however, are remarkably few; 
and the student of the recent crinoids is to be congratulated upon the 
masterly way the group has been handled by practically every worker 
upon it, and the excellent shape in which it has been left. Dr. P. H. 
Carpenter, especially, in his two magnificent monographs and_ his 
numerous other writings, giving us the results of years of study and 
research, has, by his investigations of the types of almost all of the 
earlier species, laid the foundation for a solid, stable nomenclature. 
I wish here to express my appreciation of the kindness of Dr. Leon- 
hard Stejneger and Dr. Charles W. Richmond, of the U.S. National 
Museum, who have generously lent their aid in elucidating many 
difficult nomenclatorial problems.
