Derbyshire Fossils. 129 



Art. VIII. A Notice of the Fossils met ivith in a short Tour in 

 Derbyshire. By H. H. G. 



By reading, in p. 51., " Brief Notices of Plants during a 

 Tour through North Wales," I was reminded of my own 

 short tour into Derbyshire, in the autumn of last year ; during 

 which, I was amused, and much gratified, with the oppor- 

 tunity of collecting many good, and some rare, fossils; and, 

 perhaps, the notice of the localities may be useful to some of 

 your readers who love the same pursuit; and also stimulate 

 them to give, through the medium of your entertaining pub- 

 lication, similar information, in order to assist the geologist 

 in his researches after the hidden treasures of former ages. 



My first operations were commenced at Matlock, where, 

 directly opposite to the High Tor, I found a small quantity 

 of limestone recently quarried, and rich in organic remains; 

 principally consisting of Productae, with a few Terebratulae ; 

 and, within a few yards, a lead mine, recently reopened, from 

 which I obtained varieties of madreporal limestone, fluor 

 spar, lead ore, &c. A little farther north, and on crossing 

 the ferry, I met with another small quarry, called the Pig's 

 Eye. This is but little worked, yet the scattered fragments 

 yielded an abundant variety of Productae, some Spiriferae, 

 Terebratulae, E'ntrochi (oval) ; and, much to my surprise and 

 satisfaction, a small tuberculated trilobite, differing from any 

 I have seen figured, but resembling in shape that figured in 

 this Magazine, Vol. III. p. 287. fig. 79. a. Farther on, 

 through the village of Matlock, and after passing the church, 

 the road had been recently altered, in doing which a stratum 

 of limestone was cut through, yielding, in a small space, many 

 specimens of Productae and E'ntrochi, with a few Spiriferae 

 and Terebratulae. In these three spots I collected nine 

 varieties of Productae, some of which, separated from the 

 matrix, had the appearance of complete bivalves ; but, at the 

 same time, leaving a large portion of the mantle on the stone, 

 with a fine impression of the flat valve. Workmen, and 

 others, who preserve fossils^ to make a trifle by them, are too 

 apt to be contented with the two valves, as separated from 

 the matrix ; and this seems to account for so many defective 

 specimens of this genus being found in collections. The 

 sizes of the Productae, at the Pig's Eye quarry, varied from 

 half an inch to 7 in. in breadth. 



There is a limestone quarry at Cromford ; but few fossils 

 are met with there, and chiefly Cyathophyllae, with occasionally 

 a Spirifer, a Terebratula, a iVautilus, and a few E'ntrochi. 



Upon the higher ground, at Middleton, are to be found,
