not still existed 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. vm. No. 12. Some 
fragments of a stellite, of which this Stella is supposed to be the 
analogue, is depicted in Knorr’s work, Supp. PI. VII. 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 spe- 
cimen, 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 
common yellow star-fish of Lhwydd. A petrifaction of this species 
was found at Malesme, in France ; and is figured and described by 
M. Guettard, Mem. de V Acad. An. 1/63. 
7. Stella lumbricalis lacertosa, corpore sphcerico: Linck. Tab. 11 . No. 
4. A fossil, containing a considerable portion of a stellite, resembling 
this species, is figured by Bourguet, Traite 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 pentagono, lateribus lunatis ; Linck. 
Tab. xxii. No. 35. Three specimens of a micaceous sand-stone, from 
Cobourg, with several stellites, which appear to be of this species, are 
figured by Knorr, Recueil des Monumens, 8fc. Tab. l. 1. 23. Another 
specimen is also described by M. Davila, Catal. Tome in. p. 191- 
9 . Stella lumbricalis, corpore sphcerico tuberculosa, radiis conice 
productis. Under this denomination M. Walch comprehends small
