this denomination M. Walch comprehends small detached stelliform fos- 

 sils, about the size of a lentil, which are found in St. Peter's mountain, 

 near Maestricht. Recueil des Monum. Tom n. p. 262. The body of 

 this animal appears to have been of a spherical form, and large in pro- 

 portion to the length of its rays, which are conical, and vary in their 

 number, from four or five to six or nine. The body, as well as the 

 rays, are beset with tubercles. 



10. Stella crinita, decacnemos rosacea, Linck. Tab. xxxvu. No. 66, is 

 figured as a fossil by Baier, Oryct. Norie. Tab. vm. No. 5 ; and by 

 Knorr, Recueil des Monumens, Plate vn. Fig. 6. 



11. Stella decacnemos, barbata, Linck. Tab. xxxvu. No. 64, appears 

 also to be figured as a fossil by Baier, Monim. Rer. Petr. Tab. viz. No. 2, 

 4, and 5; and in Oryctogr. Noric. Tab. vm. Fig. 4. 



12. Stella crinita polycacnemos , the Caput Medusa of Linck; Linck. 

 Tab. xxi. et xxu. Gesner, De Petrificatis, p. 31, mentions a fossil, 

 which he supposes to be a fragment of this species; and of which, it 

 appears, that fragments only have been found. 



13. Astrophyton, of Linck; or Caput Medusa of Rumphius; Cabinet des 

 Raretes & Amboine y Tab. xvi. Gesner,, De Petrificatis, p. 31, speaks of fossil 

 fragments of this animal having also been repeatedly found. This he 

 repeats, on the authority of Lhwydd, who names a fossil (No. 1132) of 

 this kind, Astropodium Ramosum; and on that of the intelligent Rosinus, 

 who also iigures (Prodromus, 5fc. Tab. x. Fig. n. No. \.) what he sup- 

 poses to be a fossil of this kind. Gesner, however, did not advert to 

 the circumstance of both Lhwydd and Rosinus having written before 

 the period at which the pentacrinites were discovered. An inspection 

 of the figures given by Lhwydd and by Rosinus will directly show, that 

 the fossils which they have figured are undoubtedly parts of penr 

 tacrinites. 



Mr. Knorr, Sup. Tab. vi. 8 17, figures various small fossil bodies, 

 which he learned came from some part of Italy, and which he considers 

 as belonging to the Stella fissa k of Linck ; but acknowledges that, even
