same, and containing: the same fossils as the fireclay which is the usual seat of 

 the coal. The use of Calliard for producing the fine sand used in the moulding of 

 iron and brass was explained, as also the pi'ocess by which the stone is reduced. 



The manufacture of firebricks, sanitary tubes, and domestic pottery from tlie 

 fireclay of the Halifax coal-seam was explained, as also the process by which 

 sulphate of iron is made from the pyrites contained in the same seam. The author 

 proceeded at some length to describe the position and quality of the irregular 

 seams of coal which are found beneath the Rough Rock, and also pointed out the 

 peculiarities of the two seams of coal called the Halifax Hard and Soft beds, 

 which are usually classed as the lowest of the true Coal-measures. The line of 

 their outcrop was also pointed out. 



The paper also contained a short description of the ancient bloomeries in the 

 disti'ict, and concluded with a notice of^ the seams of iron and coal found at 

 Bowling and Low Moor. 



On the Discovery of a Species of Starfish in Devonian Beds of South 

 Devon. By A. Champernowne. 



The only record hitherto, so far as I know, of the occurrence of Starfish in 

 British Devonian rocks, is that given by Mr. Etheridge in his list of Devonian 

 Fossils (Q. J. Geol. Soc. vol. xxiii. p. 619), viz. Protaster, sp., and ralceastcr, sp., 

 from the Pilton beds of North Devon ; therefore the discovery of a species in South- 

 Devon rocks may not be without interest. 



The localit}' which jdelded the few specimens in question is ft small quarry at 

 Inglebourne House near Ilarbertonford (about three miles S.S.W. of Totnes), in 

 slates with one or two thin gritty layers, on one of which, forming part of the floor 

 of the quarry, were the impressions. 



The dip is about S.E. (20° east of south magnetic) at 15°, crossed by cleavage 

 at a higher angle towards the south. 



Viewed in connexion with the Harbertonford limestone, and the slate-quarry at 

 Roster Bridge, the beds would appear to belong to the Upper South-Devon series. 



In the old quarries at Harbertonford the limestone and shale dip north at 10°, 

 the angle heightening to 25° close to the Vicarage ; and in the adjoining cutting 

 of the Kingsbridge road, the slates, rising to the south with undulations, are 

 apparently below the limestone. This woidd seem to produce the line of the lime- 

 stone to the north of the Ilarber at Woodcourt, and probably to the north of 

 Roster-Bridge slate-quarr}' (where iSpirifers and other fossils are numerous), and 

 hence to trough some slates in the neighbourhood of Inglebourne which contain 

 the Starfish *. At Roster-Bridge quarry the cleavage is the predominant feature, 

 the bedding being at variance with the S.S.E. dip shown on the map north of 

 Dolling, half a mile to the west. 



[The impression of the body-plates is unfortunately wanting in the specimens of 

 Starfish which were intrusted to my friend Mr. Lee ; but I venture to hope they 

 may be described by some more experienced palseontologist than myself, the object 

 of this paper being merely to record the fact of their occurrence, and to describe the 

 locality.] 



Note by Henry "Woodavard, F.B.S., on A. Champernowne's Paper. 



Two Devonian Starfishes have been notedf by Mr. Etheridge, F.R.S., in the 

 Devonian of North Devon, which he refers to the genera Protaster, sp., and Pales- 

 aster, sp., ft'cm Middle and Upper Devonian of Pilton J. 



Prof. Ferd. Roemer records fom* genera (namely, Asptidosoma Tischbeinianmn, 



* I revisited the spot in company with Mr. J. E. Lee and Mr. Paige-Browne, of 

 Inglebourne House, and owner of the quarry ; and this was the view taken by tlie latter, 

 wlio considered the roofing-slates of Roster-Bridge quarry deeper in the series than 

 the slates around liis house, and the last nearly on the horizon of the limestone of 

 Harbertonford. Our search for Starfish, however, was fruitless. 



t See 'Quart. Journ. Geol. Soc.' 1867, vol. xxiii. pp. 619, 670. 



\ Mr. E. Etheridge informs me that tliese Starfishes are both of Upp)er Devonian age, 

 and that the reference to Middle Devonian, on p. 670, o^. cit., is a typographical error.
