Remains, vol. ii. p. 224, from a specimen from Dudley in 

 the possession of Mr. Donovan : I have since seen a spe- 

 cimen, apparently of this species, in the possession of 

 Geo. Hawker, Esq. of Stroud, in Gloucestershire. 



In volume lii. of the Philosophical Transactions, is figured 

 the representation of the body of an eiicrinite or pentacrinite 

 found at Pyrton Passage, Gloucestershire, bearing, when 

 closed up, the form of a fig ; a similar specimen has been 

 since found also, on the banks of the Severn, by Mr. G. 

 Hawker. 



Sp. 6. The tortoise encrinite (Organic Remains, vol. ii. 

 PI. xiii. fig. 24) is formed of various angulated plates, dis- 

 posed in a purse-like form, five of which are pentagonal and 

 surround the mouth, having in the upper edge of each a 

 semicircular notch, from which proceeded a jointed arm 

 dividing subdichotomously : under these is a row of hex- 

 agonal plates, and beneath these pentagonal ones, every 

 plate being striated from the centre to the margin, and 

 united by fine crenulations with the adjoining ones. 



Various small substances are found, chiefly in the chalk, 

 possessing the characters of this tribe of animals, and of 

 which no recent prototypes are known; such are, 1. the 

 straight encrinite^ PL ix. fig. 5, possessing an organ of at- 

 tachment, with vertebrae, pelvis, and ramifjdng superior 

 extremity ; 2. the bottle encrinite, possessing a utricular 

 form, but divisible in its upper portion into parts corres- 

 ponding with the clavicles, scapulae, &c. of the lily encrinite, 

 PL ix. fig. 13 ; 3. the stags-horn encrinite, PL ix. fig. 14, in 

 which the arms, &c. proceed directly in a ramose form, from 

 the trunk of the animal; 4, the clove encrinite, (caryophillus 

 lapideus of Lhwydd, and other oryctologists) PL ix. fig. 13 ; 

 3. the digitated encrinite, distinguished by the extraordinary 

 manner in which its spines or arms are connected by nu- 

 merous digitated processes ; the oval-spined encrinite, and 

 many others whose forms and characters seem to mark
