$p. 1. The lily encrinus. Organic Remains, vol. ii. 

 PI. xiv. has this part formed of five wedge-shaped bones, 

 ossa innominata, which constitute the smooth circular cen- 

 tral part, round which are disposed five trapezoidal pieces, 

 ribs. On the upper edge of each of these is placed an 

 ossicle termed a scapula, and on the two superior oblique 

 surfaces of this little bone are disposed the first ossicles of 

 two arms, not connected laterally ; each of which divide 

 into articulated fingers and tentaculae, which when closed 

 bear a lily-like appearance, and when opened and expanded 

 form a nearly circular net of jointed meshes. These, 

 on closing, would secure the prey and direct it into the 

 stomach, which was in all probability placed in the central 

 cavity formed by the pentagonal base and its superincumbent 

 ossicles. 



The pentagonal base of this animal is represented at 

 PL ix. fig. 1 ; the surface of one of the cylindrical vertebrae 

 termed a trochite at PI. ix. fig. 4 ; and three of these con- 

 joined at PL ix. fig. 6 : when thus united they form a body 

 which is named an entrochite. 



No remains of this species have been found in this 

 island ; but in Lower Saxony, Westphalia, and particularly 

 in Brunswick, they are very abundant ; the remains of the 

 upper part of the animal are sometimes, though rarely, 

 found in their connected floriform state: their matrix 

 appears to be a limestone of the lias formation. 



Sp. 2. The cap encrinite. Differs from the preceding 

 in being of a more globose form in its lower part ; the base, 

 PL ix. fig. 3, partakes of the same roundness, and is more 

 simple and plain in its construction than that of the pre- 

 ceding species ; its arms also differ in being unequally and 

 dissimilarly divided. Organic Remains, vol. ii. PL xv. fig. 9. 



The fossil vertebral remains of this animal literally con- 

 stitute the rocks, considered as mountain limestone, which 

 traverse part of Yorkshire, Lancashire, Westmoreland and
