therefore, he looked upon as of the least importance. Mr. Bather also appears 
to ho of the same opinion, for he says: — “Arm characters in general may, 
however, he used as a check on other methods of classification ; they enable 
ns to correct possible errors in phylogeny.”^ Under these circumstances, 
unless other more important differences can he pointed out by those having 
a closer knmvledge of Crinoid structure than myself, P. Stephensi must remain 
associated with P. Koninckl and P. princeps. 
In the description of Phialocrimis KonincJd, reference was made to 
the peculiar broken appearance in the cast of some of the sutures, taking the 
form of distinctly separated pimplets or small nodes. Similarly, in P. Stephensi 
are the elongated prominences along the hasi-radial sutures. These crests 
could hardly exist in their present position without some outward sign of 
their presence on the plates proper, and it is, therefore, assumed that they 
did so, and moreover were not of precisely the same nature as those in P. 
Konincld. 
I Avas, in the first instance, indebted to the late Prof. W. II. Stephens, 
M.A , after Avhoni the species is named, for its loan. It was subsequently 
presented to the Mining and Geological Museum by the Executors of the late 
Mr. David Berry, of Cooloomgatta, who obtained it from the late Mr. 
William Berry, the finder.
