Altenburg, 1774, it is asserted that the Emperor of Germany offered 100 dollars 
for a stone lily free from its matrix and attached to its column. Auother and 
harder stratum under the above contains numerous crinital remains, but 
according to the quarrymen no stone lilies. Schrapland near Halle (sQatug- 
forseber St. 3.) Farrenstadt near Querfurt (Matuefegscher, St. 6.) 
There is good reason to believe that the formation in which these remains 
are found near Brunswick, corresponds with the white lias of England, as it 
appears to repose on the newer red sandstone, containing salt and gypsum, 
Description. 
The Cotumn (Pu. J.) of this animal, which is of considerable length, is 
formed of numerous round, rather thick, joints, articulating by their striated 
surfaces ; the radii marking thein being near the exterior circumference, having 
a central smooth area, through whose centre the smal} alimentary canal passes. 
As the column proceeds upwards, this simple figure of the joints appears to be 
interrupted (if we may judge from the fine specimen represented in Knorr, 
T. x1. a.) at every 6th or 7th articulation by a joint of wider diameter, and of 
a globular depressed form, having above and below it a still more eom- 
pressed one. Nearer the summit the joints become thinner and rounded 
externally, assuming the form of a much depressed and oblate spheroid. 
They are here disposed alternately, a small one between two larger ones, and 
again every other larger joint considerably greater. When close to the pelvis, 
the same alternation in size continues, but the joints assume a pentagonal 
shape, to which the radiating strie accommodate themselves. (Pt. u. fig. 3. 
PL. 111. fig. 1.) The middle of these has a pentapetalous impression or perfora- 
tion, through whose centre the alimentary canal passes. It is not difficult to 
see the reason why the columnar joints are pentagonal near the apex, since 
this is the best figure for allowing additional free motion to the first costal 
joints, which adhere to and project over the exterior side of the pelvis; the 
pentapetalous perforation or impression in the superior joints appears to be 
plainly an enlargement, though a very trifling one, of the alimentary canal, 
and also to result from the muscles acting on the interior points of the five 
plates forming the pelvis; hence this figure is obliterated in the lower joints. 
The frequeut alternations of the compressed globular joints near the upper ex- 
tremity of the column, are evidently intended to permit a greater degree of 
lateral motion, and their subsequent occasional occurrence allows its free con-
