nites and of the column number 8, below. Mr. PARKINSON represents a sin- 

 gle columnar joint of this Crinoidin his Org. Remains, Vol.ii. t. 13. tig. 69. 

 DOLIFORMIS would be a good specific name after ascertaining the genus to 

 which it belongs. 



4. Critioidal column (fig. 10. and ll.) formed of moniliform joints alter- 

 nately larger and thicker, articulating by a striated rim, having a central round 

 alimentary canal. A few small auxiliary side arms proceed from the larger 

 joints. Locality unknown, apparently Mountain limestone. 



5. Portion of a crinoidal auxiliary side arm, (fig. 12. and 13) formed of 

 thin joints, articulating by a radiating rim, and in one instance a series of 

 them, each terminating in a tubercle on one end of the longest diameter. 

 From the Mountain limestone at the Mendip Hills. 



6. Portion of a crinoidal auxiliary side arm, (fig. 14. and 15.) whose joints 

 are of equal thickness, articulating to each other by striated surfaces. The 

 external circumference shows a series of tubercles surrounding each joint, and 

 several folds the vestiges of muscularity. From the Derbyshire Mountain 

 limestone, and also figured in MARTIN'S Pet. Derb. t. 4. fig. 10. 



7. A nearly round, remarkably smooth, pentacrinal column, (fig. 7 and 8.) 

 formed of joints swelling out at their point of articulation to each other. This 

 might be easily mistaken for an auxiliary side arm of Actinocrinites, were it not 

 for the pentapetalous semi-striated articulation. I feel inclined to consider this 

 column as appertaining to a pentacrinite, claiming a specific distinction, and 

 should propose for its name PENTACRI NITES L^EVIS. Locality unknown ; 

 probably lias. 



8. A crinoidal column, formed of moniliform joints, articulating by surfaces 

 striated near the circumference, (fig. 9.) I never saw the superior portion 

 of this crinite sufficiently perfect to display the pelvis and plates resting on it 

 A slab in the possession of Mr. R. BRIGHT, from the transition limestone on 

 his estate, near the Malvern Hills, shows some fingers of this species. Mr. 

 G. HAWKEH has also a specimen from Dudley, showing the column and 

 several fingers ; and Mr. C. STOKES has transmitted me the drawing of a nearly 

 similar specimen from the same place. From the analogy of these fingers to 

 those of Actinocriuites triacouta dactylus and some other characters, I feel
