Fig. 1 - 23. Lepadocrinus gebhardi. 127 



1. The right side of au individual, sliowing the arrangement of plates, pectinated rhombs, etc. 



2. The anterior side, showing the pectinated rhombs at the base. 



3. The posterior side, showing the ovarian aperture with the surrounding plates removed. 



4. The left side of the same specimen. The prominence of the ovarian side over the opposite

6. A smaller iudividnal with the column entire and tlie body mutilated. The base of the 

 column is quite solid, showing no evidence of rings. 



6. .\nother individmal preserving the column and plates of the body, the latter somewhat 



crushed. The articulations are partially visible in the base of the column, which condition 

 is in a measure due to wearing of the surface. 



7. A small specimen showing the pectinated rhombs and structure of the body on the right 



side. The column is nearly entire, showing the articulations from base to summit with 

 almost equal distinctness. The lingers are converged together above the summit of the 

 body, giving it a pointed appearance.
