in one part of the lunated or falcated margin. Fragments of this species 

 are sometimes found in the Isle of Sheppey. 



5. Astropecten echinatus minor ; Linck. Tab. viu. No. 12. Some frag- 

 ments of a stellite, of which this stella is supposed to be the analogue, 

 is depicted in Knorr's work, Supp. PI. vn. b. 3. I obtained, at the sale 

 of some of the Marquis of Donegal's fossils, a most uncommonly perfect 

 specimen resembling this species. It is imbedded on a lime-stone, of a 

 yellow colour, and has only lost a part of one of its rays. I have not 

 been able to learn where this fossil was found. Portions, and even 

 complete specimens of stellites, apparently of this species, are found 

 among the pyrites of the Isle of Sheppey. A specimen, which now 

 lies before me, has one of its rays perfect ; and has sufficient left, of the 

 others, almost to determine that it is of this species. 



6. Stella coriacea acutangula; Linck. .Tab. ix. x. Fig. 19. The com- 

 mon yellow star-fish of Lhwydd. A petrifaction of this species was 

 found at Malesme, in France ; and is figured and described by M. Guet- 

 tard, Mem. de I'Acad. An. 1763. 



7. Stella lumbricalis lacertosa, corpore spharico ; Linck Tab. 2. No. 4. A fos- 

 sil, containing a considerable portion of a stellite, resembling this species, 

 is figured by Bourguet, Traitc des Petrifactions, Plate LIX. No. 438. A 

 very beautiful specimen, imbedded in chalk, apparently of this species, 

 was sold at the sale of the Leverian Museum. To this species the 

 small stellites seem to approximate, which are found in the fissile stones 

 of Solenhofen and Pappenheim, and which bear so near a resemblance 

 to spiders. One of these is depicted, Plate I. Fig. 15. 



8. Stella lumbricalis, corpore penfagono, lateribus lunatis ; Linck. Tab. xxn. 

 No. 35. Three specimens of a micaceous sand-stone, from Cobourg, 

 with several stellites, which appear to be ot this species, are figured by 

 Knorr, Rccueil des Monumens, S(c. Tab. L. 1. 23. Another specimen is 

 also described by M. Davila, Catal. Tome m. p. 191. 



9. Stella lumbricalis, corpore spharico tuberculoso, radiis conice productis.. Under
