geTa=among, in company with+«pivoy=lily. 
The view that Metacrinus was not described until 1884 is 
quite untenable, as in the article on West Indian stalked crinoids 
to which reference is made above a fairly complete diagnosis 
is given, and the most important differences between d/etacrinus 
and Jsocrinus (“ Pentgcrinus”) are made clear. 
Metacrinus has never had any species selected as the type; 
Doctor Carpenter records, however, that it was upon the proof 
of the plate representing his Metacrinus wyvilli that the name 
was found in Sir Wyville’s handwriting. It has seemed best, 
therefore, to select this species as the type, particularly as it is 
a very typical form. It is also appropriate to have as the type 
of this interesting genus a species named for the able naturalist 
who first discovered it.
