15. Encrinites Epuitonius. See page 13 of this monograph. The com- 
mon screw stone or cast formed in the alimentary canal of the Crinoidea, and 
exposed by the decomposition of the column. Why the author should have 
applied a specific name to the casts appears to me singular, since all the Cri- 
noidea that have a round alimentary canal will form screw stones, 
Of all the above varieties, the Baron has specimens in his collection, but he 
subjoins the following list of others, which, though not in his own museum, he 
considers worthy of specific distinction :— 
1, EncriniTEs toricatus. Our AcTINOCRINITES TRIACONTA DACTYLUS. 
2. Encrinives testupinarius. Our Marsupites ornatus. 
3. Enerinrres FLorgauis. Parxrtnson’s Org. Remains, vol. 2. t. 13, 
fig. 36. and 37. an Echinite mistaken for an Encrinus, and found by me also in 
the Mountain limestone of the Mendip Hills. Specimens of it are also in 
R. Bricut’s, Esq. collection from Derbyshire, 
A. NCRINITES TESSERATUS. V. Huepsch, t. 4. fig. 28. and 29, from the 
Eiffel. 
5, Encrinites puytouires. V. Huepsch, t. 4. fig. 30. from Lothringen. 
6. Enerinites pictus. Bourg, t. 58. fig. 207. to 209. 
As the Baron gives no description of these, and as I have not seen the figures 
to which he refers, Iam unable to give iy opinion on them,
