84 On the Localities of certain Fossils in Derly shire, 



the right of the road from Buxton to Ashhurne ; but, a3 

 these were made many years back, I cannot speak with 

 certainty as to the particular quarries, where these re- 

 mains were observed. Tn all these instances, hovvever, 

 it was only the even-jointed and ring jointed Entro- 

 chiles that were noticed. 

 Since the first volume of Derbyshire Petrifactions was. 

 puljlished, I have had a considerable quanlitv of loose En- 

 tiochites sent me from Matlock, got, as I understand, 

 on the surface of the first limestone?, near a vein of Ca- 

 lamine. This is probably the case, as many of the speci- 

 mens are fdled with that substance. Among these re- 

 li(j?iin vcii^a are several, which have not before been known 

 as Derbyshire Fossils, viz. an oval jointed Eniroc/iiie, figured 

 by Mr. 'Parkinson, Org. Bern. vol. ii. T. 13. f. 32. 40,^41. ; 

 the pyrijorm Entrovhile, Org. Rem. vol. ii. T. IG. f. 1, 2, 8ic. 

 A doUJhnn-jointed Eiilrochife, one of the joints of which 

 is figured Org. Rem. vol. ii.T. 13. f. 63 : and one or two 

 otliers, which have not hitherto been noticed by authors. 

 Conchvliolithus Finnites midus. Pctr. Deri. T. 6. f. 1. 

 Jn the first limestone at Buxton, in a stone wall near 

 the retnains of the old Roman Bridge, on the left of 

 the road, leading to Fairfield. ] have not yet observed 

 it in anv other strata than the first (3d Limestone ?). 

 Conchvliolithus Helicitcs Catillus. T. 7. f. 1,2. In shale, 

 and first and second limestone. Limestone shale, 

 Buxton, in the foundation of the Shakespeare Inn. 

 Fust stratum of limestone, Buxton, in the limestone, 

 behind the Shakespeare Inn (3d stratum ?); 2d stratum? 

 near the rocks south 1 mile (3d oV 4th stratum?]. 

 Sphcical Nautilite. T. 7- f. 3, 4,5. First stratum, Bu.x- 

 ton. Rock above the toadstone, left of mill -dale road to 

 the Lover's Leap. Second stratum (3d ?), as 1 judge 

 from tl.e appearance of the limestone, forming the 

 matrix of a specinsen, brought to me from Castleton. 

 Sulcatcd Phytolite, striaticulmis. T. 8. 9. £5. First or Mill- 

 stone Grit* stratum. l-iakewell, Gritsstone quarrv, east 

 of the town (shale-grit?). Buxton first grit quarry above 

 the Duke's stables (shale-grit?). 1 have found im- 

 pressions of it also on the coarse millstone grit, at tbe 

 back of the plantation, above the quarry just nientioned. 



' I call the first stnitum of trrit, which immedi:itcly reposes on the lime- 

 «tone shaie, the limestone jrit stratum, not because mch substance is itivari- 

 :il)!y found where this stratum appe;trs; but bec;iiise I liciieve it aUvays 

 parses into the coarse millstone grit, before the coal-soils commence. In 

 many instances, as at Bake-well, Buxton, &c. &c., close and fine grained 

 buildiiig- or freestone ,u;rit forms the mid'.lle beds of this stratuai, which still 

 loosens, as it approaches the liir.cstone shale, gradually, into a rough argil- 

 laceous gritstone.
