J, 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. Another and* 

 harder stratum under the above contains numerous crinital remains, hut 

 according to the quarrymen no stone lilies. Sohrapl*n<l near Ha

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 COLUMN (PL. 1.) of this animal, which is of considerable length, is 

 formed of numerous round, rather thick, joints, articulating by their striated 

 surfaces ; the radii marking them being near the exterior circumference, having 

 a central smooth area, through whose centre the small 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 K.NORR, 

 T. xi. 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 com- 

 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 striae accommodate themselves. (PL. n. fig. 3. 

 PL. in. fig, 1.) The middle of these has a pentapelalous 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 frequent alternations of the compressed globular joints near the upper ex- 

 tremity of the col umn, are evidently intended to permit a greater degree of 

 lateral motion, and their subsequent occasional occurrence allows its free con-
